Solar thermal power more affordable greenhouse gas reduction programme

Polaris solar PV net news: say solar energy the most environmentally friendly, but the cost was too expensive, existing conditions, solar-assisted thermal power is the best of both economic efficiency and energy saving and emission reduction, is our only way to transition to renewable energy road.

Although renewable energy developments we have made considerable progress, but in practical and economic benefits but also a challenge. This part is difficult to completely replace the existing fossil fuel infrastructure. Current solar thermal energy is a very viable renewable energy technologies that can be used to heat generation. The cost-effective storage strategy, it can be delivered through existing power baseload power. But it looks very good, in practice it is very complex, requires large-scale solar thermal power generation installations and tens of thousands of megawatts of capacity, the high cost, lack of economically attractive.

To solve this problem, scientists have come up with an interesting solution–solar thermal integration to existing fossil-fired power plant, which is to make full use of existing power infrastructure sustainable emissions reduction programme. Latest research shows that this method is not only economical, and less environmental pollution. Now, run to completely replace the existing energy facilities is not realistic, so that a combination of tactics provided time for the gradual transfer of power supply, but also for engineers to the technological upgrading of power plant provided a good opportunity.

From the engineer’s point of view, these changes will have on energy and material flows at the power plant had a profound impact. Analysis showed that higher photoelectric conversion efficiency of solar-assisted thermal power, but does not often encounter problems other solar technology into account. It is important, which can halve the consumption of fossil fuels.

Research has found that, according to the laws of physics on the Rankine cycle, in the case of using a particular type of heat engine, by solar heat transfer fluid heating up to 400 ° c can counteract the 28%~57% of fossil combustion. Converts this heat into mechanical energy, to produce electricity. Reduce fossil-fuel use in such a manner as to minor alterations to the existing thermal power plants.

Integrate solar thermal into the existing thermal power plants can reduce the burning of fossil fuels greatly reduced greenhouse gas emissions. In order to achieve this goal, the power plant should open the “energy saving” mode, using stored heat to compensate for the insufficient intensity of solar time. Peak demand for electricity after sunset this mode can also be used to ensure the continued supply of electricity.

Compared to the existing carbon capture and storage technology, reforming power plants with this model is a more effective way to reduce greenhouse gas emissions. Solar thermal integration to existing coal-fired power plant technology cost less, also eliminating the pressurized carbon dioxide storage sites.

-Integrated power plant has conducted pilot work in some places, more modular solar-thermal technology has been steadily developing. In addition, the programme venue requirements are not high, and can be adapted to various land conditions, limited size of lots of land where it can be deployed. Finally, the modular solution is more flexible, and better economic benefits, thus more small power stations of all ages.

Solar thermal power plants provide us with a combination of a strategic programme of transition to renewable energy. Solar assisted power plant has proven more economic value than solar power. However, so far, really solar-assisted thermal power plant under construction were few and far between, less than all the world’s total installed capacity of solar thermal power generation one-tenth.

Standing United States local legislative point of view, than simple solar power plant, solar-assisted thermal power plants get subsidies from the Government sector rewards are minimal. Nevertheless, the operational benefits of solar-assisted thermal power plant is still obvious, if policymakers can recognize and value the real situation, believe that this model can achieve substantial development, can make more contribution to our environmental protection.

PV “leader” plan: upgrade Accelerator

Polaris solar PV net news: mighty PV industry program of technical upgrading, first set up the Shanxi Datong. This also means that with lots of Datong in coal mining areas, implementation of PV industry in China “leader” plan first approved demonstration bases.

At the base of the bidding, including international, cgnpc, China Huadian, combined PV 12 photovoltaic businesses amounted to a 950-megawatt project development rights. Experts said that as PV “champions” has become the industry benchmark, will lead other companies to improve product quality and efficiency, thus contributing to the PV industry to upgrade and promote healthy competition across the sector.

In June this year, the national energy Bureau of industry and information technology Ministry, CNCA introduced for the promotion of Advanced photovoltaic technology product applications and industrial upgrading of the opinion (hereinafter referred to as views) that China will improve photovoltaic product market access, implementation of the “leader”.

The so-called photovoltaic “leader” scheme, which is the national energy Bureau plans to begin this year, annual photovoltaic support special programmes, the “leader” program through the construction of photovoltaic power generation demonstration of advanced technology base, new technologies application and demonstration project implementation. Meanwhile, government financial support and procurement in the future, will also give priority to the use of “leader” enterprise development technologies and products.

To this end, the National Energy Board Secretary Liang Zhipeng, Deputy Director, new and renewable sources of energy, the next step will be summed up demonstration base in Datong construction and management on the basis of experience, continues to explore and promote photovoltaic development and photovoltaic industry work together to promote a new model, a new path, “Thirteen-Five” and more long-term PV industry quality efficiency and achieve “good manufacturing” provide market protection.

“Big but not strong” forcing effect

According to statistics from the National Energy Board, first half of 2015, photovoltaic industry bucked up, new installed capacity of about 7.5 million-kilowatt, which distributed new about 1 million-kilowatt, China has become the world’s largest photovoltaic market. Solar energy industry will be the future of leading industries, “Thirteen-Five” period PV-20 million-kilowatt about 30 million-kilowatt/year of the development scale.

Though the size of the domestic photovoltaic industry and technology have been developing rapidly, but it also brings a number of problems. For example, can appear backward out of the market, advanced technology products from entering markets, photovoltaic industry overall technical upgrading slow, photovoltaic power generation engineering quality problems and other issues. Particularly with regard to technology, does not play a leading role.

According to an anonymous industry source, single component of power efficiency and battery, if countries lack of guidance, as investors are more concerned with immediate return on investment. “If the 250-watt solar panel, now crystal is generally has been upgraded to a 275-Watt, and if there is no such driver may be stuck at the stage of 250 Watts, or technical progress is slow. “The source said.

In fact, reduce the investment and the cost of PV electricity, key depends on the conversion efficiency of the battery. For investors, the two components of prices are basically the same, but from the perspective of long-term investment, increase the efficiency of the battery saving glass, back plate, aluminum frame and other packaging material costs, productivity will be split to reduce these costs. Of course, cement pile in the power plant installation, installation and labor costs will decline because of the split.

On the efficiency of current from the battery, domestic enterprises to some extent, has lagged behind the United States, Japan, South Korea and other overseas competitors. Prior to that, Suntech master “Pluto’s plan” is fairly advanced, but after all these years there was no promotion. In Japan, Matsushita battery efficiency had reached 25.6%, and multi crystalline cells is around 18%, single crystal about 19.8%. Korea 20% to 21%. United States SunPower cell conversion efficiency in 23% through 24%, and pressure on domestic enterprises on overseas markets, but Panasonic and SunPower do efficient battery business has not been affected. So, overall domestic technological progress has been slow.

From the national point of view, still hope that by “leaders” the demonstration effect of the plan, raise it a year threshold, drive the technological upgrading of industry.

Avoid “bad money” expulsion “good money”

In an interview, there are entrepreneurs expressed concern to reporters that “national policy is good, but if the implementation is not in place, will the phenomenon of bad money drives out good money. ”

For now, those low prices, low conversion efficiency of components also have a certain market. Because the entire market for high prices, high quality and lack of true identity. Although owners bid for your component has developed a high level of quality requirements, but some companies tend to bid with the lowest price. Such a result is that some smaller businesses do not meet quality requirements, but that claim to meet, and the low bid.

In fact, for the country’s “leader” targets set in the plan, excellent domestic enterprises can do it, because it is seeking the views of a lot of enterprises. Did some enterprises did not do so. The reason is that power station multi crystalline cells require 270 Watts, requested 275 Watts of single crystal, but designed to 255 Watts at design time, itself can do so high.

In this regard, the entrepreneur said, we have to go through civil and Government forces, the quality of products listed on the agenda. By companies investigation of photovoltaic products to third parties, including product quality, specifications, power efficiency, and so on, rating and ranking, ranking too poor not to play. Meanwhile, photovoltaic product sold services to follow up.

Judging from the demonstration project in Datong, Shanxi, and companies have realized that the Government cannot make the same mistakes in the past only the immediate interests to the neglect of long-term development of the industry’s mistakes. Has been involved in the selection of experts said that enterprises in the application submission and evaluation process, in accordance with the requirements of fairness and justice, using video and special supervision, ensure that the environment of excellence, all experts have signed a commitment letter.

Eventually recommended 12 enterprises in terms of investment ability, experience, performance, professional attitudes was the advancement of technology, are more convincing. Combined PV Executive Director Lu Zhenwei, China Merchants capital Managing Director said, “and this time get Cosmos 100-megawatt project development rights is an affirmation of joint integrated photovoltaic power, because this can break into the rich set of domestic photovoltaic power plant operating experience and management capabilities of enterprises. ”

Future joint PV photovoltaic large world’s first intelligent power management systems and real-time monitoring of PV cell phone APP to this project, and with the world’s leading certification body TÜV Germany TÜV Rheinland Group cooperation, the introduction of PV product testing and certification system of the whole industrial chain, into green energy photovoltaic demonstration base in Datong China card.

Meanwhile, China will enlarge the photovoltaic power generation engineering quality inspection and test standard will further improve. As the future more banks, insurance and other financial capital into the photovoltaic field, will have more stakeholders and monitoring power quality issues of common concern. Therefore, an increasing number of photovoltaic manufacturing companies will build quality inspection center, attach great importance to quality.

Industry insiders said, as the leader of the future plans of promoting Chinese market demands for high performance components will quickly upgrade. Datong 950MW floor leader demonstration projects will directly change “good money” competition.

Yingli can up in selling debt?

Polaris solar PV net news: last October, reaching a total of 1 billion yuan of “10 Yingli MTN1” bonds will expire, when the capital chain stretched Yingli can come up with money to pay off the debt?

Being a Chairman of Yingli, Miao Liansheng held a staff meeting in a year, all asset-backed, and Yingli stick together. Yingli has been through the sale of its wholly-owned subsidiaries-69 Silicon limited liability company (hereinafter “69 Silicon”) of idle land to raise hundreds of millions of Yuan to meet their debt obligations.

“Settle old accounts”

Yingli 2014 results showed that by the end of the year, its assets totaled 25.62 billion yuan, but the liabilities up to 21.66 billion yuan.

In early July, reports that Yingli talks with creditors, suspended production, Ying Li had to immediately “rumor”. But “cutoff” storm just over a week, ratings in the new century will Yingli subsidiary of Baoding tianwei Yingli new energy limited (hereinafter “Yingli”) of the main credit rating lowered to “a”, the rating considers Yingli idle capacity, risk, and more of the expiring bonds, pay pressures.

Reporter learned that, early in the expansion, Yingli to meet development needs, and bond financing. In 2014, Yingli and the State Development Bank, the export-import Bank and other debt exchanges over more than 20 banking institutions involved in short-term borrowing reached 5.54 billion yuan.

After 4 years, Yingli consecutive losses of more than $ 1.5 billion.

OFweek PV industry analyst Sun building building said, British Lee claims debt pressure main performance in three aspects: a is losses continued, British Lee net worth as 2014 only 1.3 billion yuan, debt capital than and assets liabilities rate respectively up to 92% and 95.2%; II is domestic sent debt of two home subsidiary status poor, especially days weiyingli credit qualification still in deterioration, and near two years has has obviously of Bank received loan signs; three is British Lee early and Silicon material suppliers signed long for contract, led to prepaid Silicon material paragraph amount big, Indirectly pushing up costs, that Yingli polysilicon costs at or above market levels.

However, the Sun House think Yingli debt worries in the short term. “These two installment payment plans are reimbursement plans to sell vacant land in, and Yingli be sufficient land resources. “The Sun House, 69 silicon as industrial land, currently backed by the Government have been converted to commercial use, Yingli is expected to recover after deduction of related tax cash balance of 1.5 billion yuan also Yingli also has land resource in Hainan and Tianjin, Hainan was expected to recoup cash for about 700 million Yuan.

“Zhiqian has ahead of reimbursement has first pen due in the votes,” British Lee Group President Special Assistant Yanada on in the votes to pay said optimistic, he on reporter said, British Lee has ahead of reimbursement has 1.2 billion yuan of 12 British Lee MTN1 bonds, currently, British Lee in national has about 1.6 JI w power station project reserves, and 300 MW overseas project reserves, which building project about 560 MW, “we has success sold 54 MW downstream project, this will for company brings stable ample of cash flow, Coupled with the sale of 69 Silicon land benefit 800 million ~9 million, has the ability to pay will be due in October this year. ”

Tough self-help

“Ying Li today caused the debt trap and its strategic failure has something,” some industry analysts think that Yingli market distribution in North Africa and Europe, and Europe’s most intense anti-dumping and countervailing duties, under the influence, Yingli profits continued to decline. In addition, hit by lower international prices of silicon, Yingli was the main push of “vertical integration” strategy has been overwhelmed.

Previously, Yingli employees since the explosion, Ying Li, Hainan branch due to fund shortage, wages temporarily issued by 1500 Yuan/person, later filled in the rest, middle-level employees are not, and some shop not production, employees were forced to leave.

“We have the ability to continue to provide high quality products,” while the expected bearish, but Nada said Yingli has been in production. Nada said, “recently had a big list in Chile North, two of Latin America’s largest solar photovoltaic and solar thermal hybrid power supply of 240 megawatts of photovoltaic components, of which the first phase of delivery has been completed, is preparing for the second phase of the shipment. ”

Turning to the debt crisis, Nada said Yingli has been sought by accelerating the solar power plant development, strengthen cost control, measures to reduce administrative expenses, strengthen technological innovation, promote the improvement of cash flow. “Gross margin up to 2014 from 2013 10.9% 17.3% better than the industry average. “Nada said 2015 Yingli gross margin for the first quarter reached 14.1%, 8 consecutive quarters of profit before interest and tax of the company is positive, is gradually returning to profitability.

According to reports, the first quarter of this year, Yingli total sales of 754 MW, an increase of 20%, revenue was $ 468.7 million, an increase of 8.4%, above market expectations of $ 14.1 million. “Especially in Japan shipments reached 37% per cent of the market, hit a record high, an increase of more than 100%, emerging markets (in addition to Europe, the United States, and Japan and China) developed to harvest, shipments rose about 70%. “Nada said.

PV land use problems and the suggestions

Polaris solar PV net news: PV in urban land use tax (hereinafter referred to as land-use tax) collection of recent troubles on the issue, such as in the investment phase, local government commitment to PV land use tax preferential tax policies. But after the power station was built, PV manufacturers were required each year in accordance with the land or the actual land area of paying land-use tax. Enterprises not only wonder: power station clearly is in the barren hills, unreclaimed lands and even the Gobi desert, saline-alkali land building, why do we have to pay land-use tax? Again, PV enterprises land only for the booster station, transformer substation, solar panel frame parts, “sign”, but the solar panels covering part of the actual covers an area larger, PV manufacturers tend to be resolved through rent way. So here’s the thing about PV land use taxes in accordance with the “sign” area of tax or according to plant the actual footprint (including solar panels actual coverage portion) is counted? (Note: this article is mainly aimed at large scale photovoltaic power plant and township land use tax issues discussed. )

, PV enterprises on the issue of land use tax confusion

Puzzles: PV power generation enterprises to pay land-use tax

PV power stations are generally light and no block construction of barren hills, wasteland, similar belonging to urban land, and whether they should be paying land-use tax?

Puzzle II: land-use taxes in accordance with the “sign” area, and is also levied according to the actual covers an area of

PV enterprises land only for the booster station, substation, solar panel frame parts “sign”, but the solar panels covering part of the actual covers an area larger, PV manufacturers tend to be resolved through rent way. PV enterprises shall, in accordance with land area land-use tax and is based on the actual area of levy?

Puzzle III: photovoltaic tax incentives for enterprises the possibility of securing national

As early as 2013, the Central Government issued the opinions on promoting healthy development of PV industry in China (guofa [2013]24), in which the clear tendency of the photovoltaic industry in terms of taxation and land policies, but the State does not support rules to implement it. In this regard, the PV companies to obtain state tax incentives?

Second, understanding of photovoltaic companies confused issues

(A) whether urban industrial planning is to determine whether power station standard of levying land use tax

The interim regulations on urban land use tax (hereinafter the regulations) provide, in the cities, counties, towns, industrial units and individuals using land in the area, land-use tax taxpayers. Land use tax levy scope are cities, counties, towns, and industrial and mining areas. On this, on land using tax several specific problem of explained and provisional provides (IRS to Word [1988] No. 015,), on tax range for has clear of explained, that city of tax range for urban and suburb; County of tax range for County Government where of town; formed town of tax range for town government location; workers mine is refers to business compared developed, population compared concentrated, meet State provides of formed town standard, but yet established town formed of medium industrial and mining enterprises location. Cities, counties, towns, and industrial and mining areas the tax base, drawn by the provinces, autonomous regions and municipalities.

At the time of paying land-use tax by tax authorities require, photovoltaic power generation enterprise should first check and confirm that the power generation sites fall into the range of urban and industrial and mining areas; if not falling into the power generation enterprises should firmly reject acts of tax authorities levied. However, such as photovoltaic power plant belongs to the scope of urban industrial district planning and land use tax shall be paid according to existing regulations.

Noteworthy is that cities, counties, towns, and industrial and mining areas of specific tax base is made up of all provinces, autonomous regions and municipalities shall be determined. Therefore, even in the PV power plant project or the construction phase of the project does not fall into the urban industrial and mining areas, not part of the scope of land use tax, but the local government at the provincial level by adjusting the scope of urban and industrial and mining areas, can still make it to the tax conditions.

(B) the provisions of the State on how to determine the taxable area PV power station is not clear

The provisions of the Ordinance, land-use tax to the taxpayer actually occupies a total land area of the tax basis, organizations measure of land area, determined by the people’s Governments of provinces, autonomous regions and municipalities according to the actual situation. However, the Ordinance does not specify the actual nature of the occupation of land and judging criteria.

In addition, the current national policy allows PV booster station, transformer substation, solar panels support the use of “sign” way for land clearance, solar panel-covered portion may go through the land acquisition procedures (actually to apply, tenant). But whether according to levy land of area as meter tax area, practice in the around of tax organ of meter tax standard does not unified, which a views think, PV power station of Sun Board cover part does not change original land uses, “points levy” area for power station actual using of land, so can according to points levy area meter tax; but also has views think, land using tax to taxpayers actual occupied of land area for meter tax according to, Sun Board actual cover part also belongs to power station accounted for to, so should by power station all accounted for to area meter tax. As far as I know, photovoltaic power plants generally have access to the tax authorities in accordance with the land area land-use tax, but for solar panels to actually cover some taxes often are difficult to accept.

On this issue, southern weekend reporter had conducted in-depth research in 2012, and released in August of that year the station Gobi gold rush: a pie or a trap? Disclosed in the reports, although the State actively encourages and develops solar-power industry, but in practice has been “variation” in local chip to attract foreign investment. If a land-use tax, according to estimates, annual tax is 5 times of the past-times. Energy Research Institute, national development and Reform Commission of experts believe that power plants take up most of the desert, saline wasteland, introducing related costs more than the tender of the land-use tax (land) or higher, is unreasonable and inconsistent with national policy.

I think, the main purpose of levying a land-use tax is to rational use of urban land, strengthening the land use tax adjustment function, guiding taxpayers to cherish land resources, ease the contradiction between supply and demand of land. However, large-scale PV power station were built on the ground in the more remote regions from town, which actually is the effective utilization of land, intent does not belong to the land-use tax adjustment range. So, for better of promote PV power industry of development, national has necessary system cleanup town workers mine planning divided standard, on obviously not reasonable of should to corrected; in implementation level, for currently has fall into town mining district of PV power station, in national on “land using tax of meter tax area” introduced explained sex file Qian, tax organ should made on taxpayers favourable of understanding, that for PV power station according to land area meter levy land using tax.

(C) countries are currently on the PV industry has no explicit land-use tax policy

Currently, all provinces, autonomous regions and municipalities for the PV industry are related to the promotion of the Government policy of. But this tax for urban land use tax, State administration of taxation and the Ministry of finance is not for photovoltaic power generation enterprises special tax rules.

The end of 2014, the State Council issued the notice of tax preferential policies, such as on clear norms (“2014”, 62nd), call for a full liquidation of national tax policy. On May 10, 2015, the State Council promulgated the notice on incentives such as tax-related matters (“2015”, 25th) suspended the 62nd article cleanup. 25th article clearly in various regions and sectors for future development of new preferential policies, relating to tax or non-tax revenue of the Central Government’s approval to set up, shall be reported to the State Council for approval before implementation. I understand, local government permission to develop tax incentives has been on the State Department, and had already issued the relative effectiveness of preferential tax policies are also subject to certain restrictions. Photovoltaic companies such as wanted to achieve in the future land-use tax incentives, must be approved by the State Council.

Three, on the recommendation of the land use tax on photovoltaic power generation business

Recommendations: the importance of project research, land use taxes as an important consideration in project investment

Photovoltaic power generation at the project stage site land planning and land from falling into the scope of urban and industrial and mining areas to be fully understood. For land areas are land-use tax, should pay attention to land-use taxes to finance the project impact future earnings estimates, provides support for the project.

Recommendation II: make sure PV power stations belong to the scope of China’s land using tax

Photovoltaic power generation business is required to pay by tax authorities and township land use tax, enterprises should first check and confirm that the power generation sites fall into the range of urban and industrial and mining areas; if not falling into the power generation enterprises should firmly reject acts of tax authorities levied; in case of need, also through judicial procedures to safeguard their legitimate interests of tax should be considered.

Recommendation three: by all means reflect problems towards the authorities issued preferential tax policies

Photovoltaic power generation enterprise land use tax collection and payment of final resolution of the confusion, dependent on the Ministry of finance, the State administration of taxation issued a clear tax policy. Therefore, the PV industry efforts should be made through various means, primary taxation issues reflect the right to tax policy makers. First of all, photovoltaic power generation companies can leverage the power of industry associations, obtaining tax incentives. I learned that Chinese Photovoltaic Industry Association was established in Beijing on June 27, 2014, the Association under the guidance of the Ministry of industry and information technology, the Ministry of Civil Affairs, based on preparatory China PV industry association formed. Photovoltaic power generation companies can use the Photovoltaic Industry Association, focusing on communication with the Ministry of finance and State administration of taxation, the feedback of PV industry difficulties and actively seek to tax benefits related to urban land use tax and other policies, to encourage policies to promote PV industry in the country can truly be born. Second, the solar products can also belong to the Group communicate directly with the State administration of taxation, seek tax breaks. For large State-owned power generation enterprises should make full use of the Group’s dominant position, fighting for direct communication with the State administration of taxation, reflecting practical problems encountered by the development of photovoltaic industry, seek appropriate tax incentives and support.

Since the launch of a new round of administrative examination and approval system reform since the tax reform of the system of administrative examination and approval system is advancing. In the new political and economic environment, photovoltaic power generation enterprises should attempt through various means, to take advantage of opportunities, the practical tax issues up to reflect grass-roots, to attract the interest and attention of the relevant departments, PV enterprises encounter land-use tax and the issue was finally resolved.

PV module white lines (static lines) Genesis

Polaris solar PV net news: Abstract: by analyzing the white lines on the surface of the photovoltaic modules components and electrostatic discharge simulation white line-producing process, discuss the possible reasons and avoiding methods of white lines.

Key words: photovoltaic modules, white lines, static lines, lightning lines

Background

PV components in the production process, occasionally white lines on the surface of the cell, causing the component degradation. Some white lines, such as photovoltaic solar cells, glass in front of the laminate mechanical injury can cause such as a scratch cell (Figure 1), scratches the glass (Figure 2) and wear glass (Figure 3) the white lines. This line through the easily discernible to the naked eye, and can be found in the component before laminating, so prevention is also easier in the production process. And the other white lines are not caused by mechanical damage, the appearance of lightning, and often will split, branching at the end (Figure 4). Before the laminating without any open sign, only after the laminate will be found. And often changed after EVA film, this phenomenon does not occur, so component plants tend to put the blame on EVA film production quality problems. EVA film formula, manufacturing process without making any changes, so there is no way to prevent this phenomenon from happening again. When there is a similar quality issues in the component, component factories often require EVA film white line works bought components to resolve, but the actual cause has been identified.

Figure 1 scratch cell

Figure 2 glass scratches

Figure 3 glass wear

Figure 4 static lines

Some companies refer to this phenomenon as the electrostatic sheath in foreign countries, but whether it was caused by static electricity, did not see the domestic enterprise simulation process of white lines. As we all know, EVA resin is a poor conductor of electricity, due to their excellent insulation properties, is widely used in wire and cable insulation. But due to the high content of VA EVA high transparency, enabling it to a lot of is used for encapsulation of photovoltaic modules. In recent years, through the continuous upgrading of technology, volume resistivity of EVA film from the early days of 1013 ohm cm gradually upgrading to current 1014 to 1015 ohm cm. Volume resistivity of EVA film is associated with the white lines? White lines appear in the summer, and humidity of air?

White line composition

Analog component white line before the haiyouwei component analysis first site of white line. White line first sampling. Process is damaged components, batteries and EVA film from glass strips. The white line in the sampling area and sealed in epoxy resin, slice-135 ℃, using an optical microscope, electron microscope and spectrum analysis, infrared spectrum analysis method to check if the white line contains impurities or other non-EVA material.

Figure 5 sample

Figure 6 sample

Using an electron microscope (Figure 7), found no discernible white line locations of impurities. Using spectral analysis, did not found any in the white line containing metals or other components of inorganic substances (Figure 8).


Figure 9 infrared analysis of SEM photograph

Figure 10 Figure 9 position the IR spectra

From the IR spectra (Figure 9, Figure 10), white part of sampling only EVA resins (NE280PV) and solar (photovoltaic solar cell components) the absorption spectra can indicate that the position of the white sample no other organic impurities.

From the above analysis shows, white line composition is still EVA resin or a high proportion of components is EVA resins, no or almost no organic or inorganic impurities.

EVA film experimental simulation of electrostatic

In EVA film production and cutting process in the accumulation of static electricity, when large quantities of charge occasionally in the form of static electric arc discharge. Sea power laboratories through electrostatic equipment generate static electricity and electrostatic arc release directly to EVA adhesive film on the surface, thereby simulating EVA film release of static electricity on the surface and observe the electrostatic potential consequences of release.

This study used J2310 induction motor, as shown in Figure 11 and Figure 12. When two quick spins, gathered at two discharge bulb with different charge, EVA film there in order to simulate the discharge process.

In the experiment of electrostatic discharge, first observe the film surface changes after discharge, again with glass-EVA film-cell–EVA film structure of the back panel PV modules laminated to the general process, positive changes were observed. Experimental use of electrostatic voltage and the actual situation is not controlled. This study compares two variables, its possible effects on results.

Using three different volume resistivity of EVA film, observe whether the volume resistivity affected white lines;

Same volume resistivity of EVA film, process it with different relative humidity, observe the white line is different.

The results were as follows:

1) after release of static electricity, in EVA film surfaces there is no obvious traces. This may be because EVA film after embossing the surface, causing surface pale to white or rubber membrane surface of the changes observed.

2) laminated EVA film according to the PV module structure, find all the film white lines are being created.


These experiments concluded that static electrical arcs when you release the pressure after the white lines were found in EVA film. White lines with EVA film volume resistivity and the relative humidity of the environment seems to matter very much. Humidity range and time frame in this experiment in the lamination of the specimen produces white lines.

White lines mechanism analysis and prevention

EVA film is an electric insulator, and any insulator friction creates static electricity. Electrostatic voltage can reach very high, when accumulated to a certain degree, the arc forms a direct release charge. In EVA film, the release of static electricity caused momentary short circuit the heat of the moment, and high temperature of EVA film incentives. Due to its tiny range can reach very high temperatures and cause peroxide reacts violently in EVA film leave traces, or EVA resin is penetrated by charge similar cable insulation breakdown led to traces left by tree. Both might have occurred within a very small range of sharp cross-linked, it may also be direct decomposition of peroxidase, EVA resin may be left traces of breakdown after breakdown. In short, the trace component after EVA laminated resin through the melting and become transparent, very evident in blue or black piece emerged. This white line obvious characteristic is the shape is similar to lightning, fork, and vary in size.

If the reason of the above analysis is correct, to avoid the appearance of EVA white lines in the film, we try to avoid EVA film the accumulation of static electricity on the surface. EVA film in both the production and use of contact with other insulator and static …

EVA adhesive film during the production process, there are two kinds of winding way, friction winding and rewind. Use a rubber friction winding roll film EVA with EVA film synchronization into paper tubes cores. Due to the rubber roller is an active roll with motors, so EVA rubber membrane and rubber roller is synchronous, so although the winding ways in the name of “friction” in two words, actually EVA film and friction between the rubber roller is not serious. In addition due to the winding way to get the film rolling loose, so you’ve got good EVA film layers and friction between the layers is also very small. Rewind is another winding way, the use of a metal core rotation rolling. Rewind rotating from the metal core, so charging more closely EVA film easy, friction between EVA film accumulated electrostatic charge. Rewind device in front of the metal core has a flattened roll of rubber, the roll is a passive roll, totally dependent on EVA film drive, here is a very easy to generate static sites. Either way, theoretically speaking, rolling from the Center are more prone to static electricity.

In EVA film cutting process, EVA film easy accumulation of static electricity. If the cutting process using a rubber roller as a passive roll in the transition, it will a lot of EVA film surface charge accumulation. And if the platform using a glass cutting machine, the location is an easy charge accumulation. Automatic cutting machine for complex structure as a result of a number of rubber rollers as a show flat, transitional purposes, its easier than simple cutting machine in the EVA film caused the accumulation of electrostatic charges. Speaking from the principle, use of artificial cut-cut film platforms due to no or very few passive turning rubber transition rollers, and automatic cutting device less prone to electrostatic charges accumulate.

How to avoid in EVA film production and a utility point accumulation of electrostatic charge is one of the most effective methods of preventing white lines appear. Haiyouwei through improving the production equipment and the prevention of EVA film layers and layers between the friction and prevent the emergence of white lines. And component plant in EVA film cutting process should also be effectively avoided in film and other insulating parts friction.

Concluding remarks

Due to white lines are seriously affecting the appearance of PV modules, lower the quality of the components and leading to scrap or downgrade, in EVA film manufacturing and cutting process should try to avoid the accumulation of static electricity. Such as the use of friction winding device, try not to use rubber flattened roll (or flattened roll and then release the charge by adding a metal roller), cutting machines with as little as possible, without the rubber rollers, etc.

Due to the photovoltaic module white lines may also have more influences, this article does not explain all the questions, such as more likely to occur in the summer and white lines, white lines are irregular and so forth and the white lines causes also need further study and analysis.

Department of energy Sun PV status: half-abandoned photoelectric amounted to 1.8 billion

Polaris solar PV net news: in March this year, released by the National Energy Board 17.8 million-kilowatt PV installed capacity goal for this year, and the completion of the first half of this year but is not optimistic. Recently, the National Energy Board released data shows that first half of the year, national new photovoltaic power installed capacity reached 7.73 million-kilowatt, including new PV installed capacity 6.69 million-kilowatt released distributed PV installed capacity of 1.04 million-kilowatt, only to achieve the annual target of 43%.

In this regard, the PV industry experts, said Zhao Yuwen, “Judging from the data, PV installed capacity this year progress has been slow, 17.8 million-kilowatt wants to finish the year a challenge, since the current progress of distributed PV installed capacity is not ideal. ”

Goals in first half of 40%

National Energy Board issued by 2015, programmes to inform the construction of photovoltaic power generation, according to the nationwide scale PV power station is set to 17.8 million-kilowatt this year, far more than the 14 million-kilowatt 15 million-kilowatt and 2014 for the record in the draft plan. It is worth mentioning that 2014 real new grid-connected PV capacity 10.52 million-kilowatt, only installed capacity target of 70%.

Data shows that first half of the year, national new photovoltaic power installed capacity of 7.73 million-kilowatt, only to achieve the annual goal 17.8 million-kilowatt 43%, including new PV installed capacity 6.69 million-kilowatt, new distributed solar PV installed capacity 1.04 million-kilowatt.

Zhao Yuwen on daily economic news reporter said, “large PV power station by local government, and grid and PV enterprise unified planning, progress problem not too big, but distributed PV power station, due to scale is unlikely to, and most concentrated in roof, for roof of area, and grid and installation conditions requirements are compared high, this on progress effect larger, to currently progress speed view, this year wants to completed annual of installed target difficulty very big. ”

Parts of absorptive capacity

National Energy Board statistics showed that earlier this year when China PV power generation 19 billion-kilowatt, abandoned when optical weight of about 1.8 billion-kilowatt. Worth noting is that abandoned photoelectric mainly occurred in Gansu province and the Xinjiang region, where the abandoned power light 1.14 billion kWh in Gansu province, abandoned 28%, Xinjiang (Regiment) left electro-optical 541 million kWh, abandon rates 19%.

According to press reports, resulting in abandoned optical reasons, is mainly caused by cuts, a number of PV power stations because of power rationing measures on line rate of elimination from the last 60% to 30%,70% power network wasn’t working. In fact, leaving behind the optical also reflected the power station development and power out of the serious mismatch between channels. “The sharp growth of the installed capacity in the Northwest, but due to lack of power transmission capability, resulting in abandoned optical. “Zhao Yuwen, told reporters.

Also, China can renewable energy learned Deputy, Chairman of Meng Xiangan in first half of PV summary Conference Shang said, abandoned photoelectric of situation main is because development layout not reasonable, and local power elimination na capacity insufficient, and grid construction delay, and outside sent transmission channel capacity limited,, “currently China exists grid construction and PV power station project of approval way and construction cycle not match of problem, caused PV power project to synchronization design, and construction and voted shipped. In addition, due to a power, and power grid planning and construction does not match the limited absorptive and market space, resulting in Hexi corridor of Gansu province since last year there have been more serious in some areas, such as abandoned light power. ”

Why renewable energy demonstration area in China “flowers” Zhangjiakou?

Polaris solar PV net news: on July 29, the national development and Reform Commission announced that the State Council has recently approved the establishment of renewable energy demonstration area in Zhangjiakou, the demonstration zone of Zhangjiakou City, Hebei province, China renewable energy development plan also released. This means Zhangjiakou will first try to engage in a “energy revolution” in practice, the first to break down institutional barriers, and explore new modes and mechanisms in renewable energy development.

Why the demonstration area “flowers” Zhangjiakou? Where a national renewable energy development “Pathfinder”?

Natural + industry based demonstration area “flowers” Zhangjiakou logical

“The dam is a wind, blows from the spring to winter”, said especially in Zhangjiakou bashang region people’s frustration. Now, the past developments are turning into Zhangjiakou new development advantages of disadvantages.

Zhangjiakou is one of the North wind and solar resources are the most abundant. Local is the nation’s wind energy-rich region, particularly in bashang region in Mongolia plateau South-East of, at an altitude of 1500 meters to 1600 meters above sea level, is Mongolia North China plain’s main air gateway to the cold air at high altitude, wind resource advantage is obvious, wind energy resource development amounted to 40 million-kilowatt and more. Meanwhile, local class II regional solar energy resources, is the area of our province’s most abundant solar energy resources, solar power can amount up to 30 million-kilowatt per cent. In addition, Chicheng, Huailai counties in Zhangjiakou rich geothermal resources, with an annual output of 2 million tons of biomass resources.

With this advantage, Zhangjiakou in “herd daily” March forward on the road of new energy industries. County, Zhangjiakou City, NDRC Deputy Director Guo Junfeng introduced, as Beijing Jin JI area important of ecological conservation district, and China important of can renewable energy production base and power conveying channel node, Zhangjiakou in recent years vigorously development can renewable energy industry, has “national scenery storage lost test center”, and national first wind electric research monitoring test base and wind machine Assembly, and leaves manufacturing, production enterprise, preliminary formed has covers development application, and equipment manufacturing, and technology development, and technology service, relative perfect of industry system.

In recent years, Beijing-Tianjin-Hebei smoggy weather, from a side note the unreasonable energy structure in Beijing-Tianjin-Hebei region. According to statistics, Beijing-Tianjin-Hebei area 2014 when the total electricity consumption of about 500 billion-kilowatt, including fossil fuel power accounted for more than 90%, urgent needs for renewable energy development in the future, this model offers a huge market for renewable energy development.

Zhangjiakou new energy Association Zhao Chongli said the location unique in Zhangjiakou, Beijing-Tianjin-Hebei region, Northeast radiation link points to the Northwest, is an important production base for renewable energy and transmission channel nodes. Accordingly, the model of “Whispering” Zhangjiakou, of course.

Pioneering + innovation model for the national renewable energy development “Pathfinder”

Experts believe that this plan was launched, by pioneering and innovative demonstration in the local area, explore new modes and mechanisms in renewable energy development, can form a replicable and replicable experiences, for the national renewable energy development “Pathfinder”.

Scope of planning in Zhangjiakou as the core region, radiation and other surrounding areas of Beijing, Tianjin and Hebei. Planning for 2015-2030, which recently for the 2015-2020, forward for the 2021-2030. Renewable energy development plan for Zhangjiakou has very high goals, proposed renewable energy consumption accounted for total final energy consumption in 2020 up to 30% by 2030 50%.

Deputy Wang Zhongying, Director of the Energy Research Institute, national development and Reform Commission said that, in the face of institutional mechanisms for restricting the development of new energy, the new energy demonstration area in Zhangjiakou pioneering, explore new mechanisms for renewable energy market development, new paths, this model is particularly significant.

Renewable energy demonstration area in Zhangjiakou promote institutional mechanisms, business models and technological innovation, the establishment of new large-scale integration of renewable energy power system planning system, electric power market system, regional integration mechanism and benefit compensation mechanism.

Guo Junfeng introduced, planning based Zhangjiakou can renewable energy model district construction of based conditions, clear has next focused implementation of can renewable energy scale development, and big capacity storage can application, and intelligent of transmission channel construction, and diversified application, four engineering, proposed has build low carbon Olympic area, and can renewable energy technology venture city, and can renewable energy integrated business district, and high-end equipment manufacturing area, and agricultural can renewable energy cycle using model district, five big function district.

Local absorptive + power delivery, promote economic restructuring and green and low carbon development

Zhangjiakou renewable energy total installed power capacity of about 7 million-kilowatt last year, but network maximum load is only 1.85 million-kilowatt in the region, inadequate external transport capacity for renewable 4 million-kilowatt renewable power severely limited. Taking into account the potential for renewable energy development in Zhangjiakou over 50 million-kilowatt, and external channel and absorptive capacity-building needs urgent.

In terms of promoting new energy local absorptive, Zhangjiakou has been exploring. Data Center, located in zhangbei in bashang area attracts well-known companies such as Alibaba, zhangbei cloud data center upon completion, will reach 5 million servers scale, when the annual electricity consumption of about 20 billion-kilowatt, the effective promotion of new energy to dissolve on the spot.

According to the plan, by 2020, the Zhangjiakou 55% of electricity consumption from renewable sources, all urban public transport, 40% of living 50%, commercial and public buildings energy come from renewable sources, 40% of industrial enterprises to achieve zero carbon emissions. By 2030, 80% of electricity consumption from renewable, fully formed mainly of renewable energy system.

Through the development and application of large-scale renewable energy will drive the local Smart grids, in Zhangjiakou new energy vehicles, emerging industries such as new materials, modern service industry development, promote economic restructuring and green and low carbon development. Zhangjiakou expand local renewable absorptive capacities, adjust the economic structure at the same time, will increase the output of Beijing and Tianjin.

In June, China polysilicon still imports more than 10,000 tonnes

Polaris solar PV net news: according to Chinese customs statistics, in June 2015, China’s imports still exceeded 10,000 tons of polysilicon, cumulative imports 60088 tons in the first half, including through imports in the processing trade manual polysilicon has 60.3%. However, the Handbook is expected to be terminated at the end of August, foreign imports is expected to reduce the amount of polysilicon.

According to the Association of colored silicone industry branch reports that imports in June 2015 10942 tons of polysilicon, which imports from Korea 4833 tons, price US $ 15.8 yuan per kg. United States imports 2202, 2196 manual tons through processing trade imports, import price of $ 14.25 Yuan per kg. Germany imports 4420 tons, purchase price $ 19.41 Yuan per kg. June import price of polysilicon as a whole can be said to have fallen to historic lows.

In the first half of 2015, of the United States, South Korea and Germany imports 51595 tons of polysilicon, which United States imports 10903 tons, Korea imported 24033 tons, Germany imports 16660, 8493 tonnes were imported in other regions, accounted for only 14.1%. Import price US $ 19.15 per kilogram, hit a new low, 12.1% less than a year. Among them, the United States imports into China’s polysilicon through more than 90% of the Handbook, so not being levied anti-dumping taxes, Germany Wacker has a certain proportion of polysilicon is borrowed from the Handbook into China; Korea dumping tax only applies to two major polysilicon companies 2.4%, 2.8%, imports did not pose a threat. Imports of polysilicon in China in the first half of severe oversupply and prices continued to dip.

Colored silicon industry branch of the Association believe that re-examine the double rate, stops, such as the Handbook, effectively cutting foreign polysilicon dumped into China’s situation.

Guangdong be added within the three-year clean energy investment of 147.4 billion yuan

Polaris solar PV net news: optimizing the structure of energy not only to purify the air, also present opportunities for the development of clean energy.

This week, the National Energy Board in the first half of the Conference introduced the national energy situation, the current energy consumption pattern of slow growth and the easing of supply and demand in the market, offers the opportunity of adjustment and optimization of energy structure, proportion of clean energy further.

Clean energy “green wind” is blowing to the South. Provincial development and Reform Commission issued this month, the latest on accelerating the construction of our province’s clean energy plan, depicting me, nuclear power, natural gas, wind power, solar power and other renewable energy development blueprint. The programme, 2015-2017, the total new investment in clean energy projects in the province about 147.4 billion yuan, self-financed investments for the enterprise.

Nuclear power and natural gas are “big head”, added investment of 56 billion yuan within three years and 50.8 billion yuan by 2017 than 2014, new nuclear capacity 6.8 million-kilowatt, new supply capacity of about 12 billion cubic meters of natural gas per year.

Clean energy more than account for the first half of 17%

“The traditional energy industry demand fell sharply in the first half, energy production, investment and imports declined, overall easing of energy supply and demand. “The Deputy Director of the national energy administration Liu Qi pointed out in analysis of China’s energy situation.

The first half of the four major coal industry in addition to the chemical industry, electric power, iron and steel and building materials industries have reduced coal consumption, and low energy consumption, faster growth in value-added industries with high energy consumption, energy consumption of the new hot spots and bright spots emerged.

Like clean energy to improve: the first half of the non-fossil fuel electricity generation rose 16%, non-fossil energy accounted for 22.9% of electricity, improve 3% over the last year. Apparent consumption of about 91.5 billion cubic meters of natural gas, an increase of 1.4%.

Head of the Department of planning and Finance of the Department of environmental protection said at a forum recently, expects the first half of this year, China exceeded “Twelve-Five” emission reduction tasks. Proportion of clean energy in the first half has accounted 17%, planned by 2020 the clean energy share, 15% are expected to be finished ahead of time.

“For a long time, thermal power supply capability and stability, while its energy consumption and emissions are relatively large, but has been a major source of power, and wind power, nuclear power and other alternative energy, as supplementary or auxiliary means, in the case of a general easing of supply and demand of energy and clean energy to play a greater role.” A wind farm in Guangdong Province, told Xinhua.

In fact, Guangdong to develop clean energy conditions. Provincial development and Reform Commission official, Guangdong Province is located in the southeast coast, rich in renewable energy such as wind, solar, and has great development potential, nuclear power plant is rich in resources, with the conditions for large-scale development of nuclear power; natural gas market. “After years of development, clean energy development and utilization in Guangdong reached a certain scale, while promoting the development of related industries. ”

However, the official also pointed out that currently still in clean energy in our province are restricted, such as the high cost of natural gas, natural gas consumption is only 5% per cent of the province’s total energy consumption, construction of natural gas pipelines and gas storage facilities cannot meet the market demand. Photovoltaic roof owners benefit from limited, offering lukewarm, distributed PV roofing resources required implementation more difficult. “Continue to accelerate the development of clean energy to improve the energy supply capacity, optimizing energy structure, drive the development of related industries and promote economic growth is of great significance. ”

In this regard, the provincial development and Reform Commission recently issued the Declaration on accelerating the implementation of clean energy in our province-building programme (hereinafter the programme) for the development of nuclear power, natural gas, wind power, solar energy and other four clean energy plan.

Support

Photovoltaic subsidy will increase

In addition to the proposed objectives and project engineering, also from the industrial, financial and other aspects of the programme, made a series of support mechanisms. For example put forward in accelerating clean energy use at the same time, actively promoting industrial development. Include a focus on the development of megawatt-class wind turbine sets of units manufacturing industry, by 2017 and 5 MW and above large offshore wind turbine manufacturing and application. Strengthen the study of solar efficient photoelectric conversion technology, key technology bottleneck breakthrough solar cell manufacturing equipment, promote the development of industrialization of solar cells.

At present, Jiangsu, Zhejiang, Shanghai and other coastal provinces in the State subsidy policy was further based on the provincial as well as city and County subsidies, rapid development of photovoltaic power generation. In this regard, clear for the first time in the programme, will refer to the practices in other provinces, according to province, from coal-fired power plant electricity price in the lower left part of the funds for wind power and solar power subsidies. In addition, this year will promote the Sanshui, Foshan, Guangzhou conghua, qianhai in Shenzhen national demonstration area for distributed PV applications.

The programme also requires statistics, Tsunenobu and environmental protection sector solar power consumption into cities and enterprises energy saving and emission reduction. Support elimination of distributed PV units according to the conversion of energy or reduce the emissions involved in relevant transactions. PV power generation projects are encouraged voluntary carbon emission reduction trading.

Guangdong

Development of nuclear power and wind power and natural gas speed

Is nuclear power to provinces in the country, Guangdong Province, Xinhua learned from the programme, within three years, the Guangdong nuclear power station building will be significantly faster. Provincial development and Reform Commission, “said uranium resources and nuclear power plant in Guangdong Province is rich in resources, with further strong advantages and conditions for large-scale development of nuclear power. ”

Under the programme, by 2017, Guangdong Province built nuclear power installed capacity will reach about 14 million-kilowatt (from 2014, new installed capacity of 6.8 million-kilowatt), nuclear capacity under construction about 4.7 million-kilowatt above.

Key projects include the completion in 2016 Yangjiang nuclear power station unit 3rd (1.08 million-kilowatt) and Taishan nuclear power unit 1th (1.75 million-kilowatt), completed in 2017 Yangjiang nuclear power unit 4th (1.08 million-kilowatt) and Taishan nuclear power 2nd unit (1.75 million-kilowatt).

Noteworthy is that Guangdong will form mainly to major investment projects of nuclear power in the future, effectively promote the development of related industries improve the nuclear power industry. Clean energy investment plan of Guangdong province shows that Guangdong will build nuclear fuel conversion, enrichment, manufacturing integration projects.

As rich in wind power resources of Guangdong Province, will be in accordance with the “land before and after the sea”, “after the first offshore, high seas” principle, developing wind power. Onshore wind power capacity in our province this year will reach 3 million-kilowatt by 2017, Guangdong onshore wind power capacity target is to reach 4.2 million-kilowatt (capacity about 1.9 million-kilowatt), offshore wind will be at 300,000-kilowatt.

As energy consumption province and Guangdong’s demand for natural gas is on the rise, its development and use will continue to grow rapidly. Introduce provincial development and Reform Commission, the province will speed up the construction of gas main pipeline network, especially Guangdong Province, Western Guangdong natural gas main pipeline network construction to speed up the completion of Guangdong Province, Guangdong LNG project pipeline project, the West-East gas transmission line, Guangdong, LNG project in Western Guangdong, Guangxi regional project and associated works.

Under the programme, by 2017, Guangdong will build a natural gas supply capacity of about 47 billion cubic meters/year (new natural gas supply capacity of about 12 billion cubic meters/year), supporting the gas main pipeline network built around 2863 km (add some 863 kilometers of pipe network), built about gas 20 million-kilowatt (capacity about 6.5 million-kilowatt).

Observation

Energy structure adjustment to benefit air improvement?

According to data published by the Department of environmental protection, the first half of PM2.5, PM10, sulphur dioxide and nitrogen dioxide average concentration was decreased compared with air pollution situation is significantly improved, with positive changes in the structure and the amount of energy consumption in China are closely related. Analysis of the national energy administration, reduction of coal consumption, increase non-fossil fuel electricity generation, to contribute to the improvement of air pollution.

Same for Guangdong. First half of the province’s air quality continues to year improvement. Meanwhile, Guangdong’s industrial enterprises above the designated size of raw coal consumption dropped 5.5%, manufacturing integrated energy consumption fell 3.8%, comprehensive energy consumption of high energy-consuming industries fell 5.2%.

“Improving air quality through end treatment is far from alone, industrial structure, energy structure and growth factors will have an enormous impact on the control of air pollution. “Provincial environmental monitoring center expert, told reporters.

The experts, from the perspective of energy pollution emissions, need to adjust the energy structure, Guangdong Province, should increase the proportion of energy away from coal in the future, especially in renewable and clean energy. In recent years, the province’s energy saving and emission reduction work to good effect, million GDP energy consumption in China and Korea closer, but with the United States, and Japan and other developed countries there is a gap, there is scope for further improvement of the industrial structure.

Adjustment of energy structure can make motor vehicle emissions. The expert for example, 2013 is 11.1 per hundred persons of Guangdong Province motor vehicle ownership per hundred people, higher than the national average. With supplies of natural gas and other clean energy capacity increases, the Government increased the promotion of electric vehicles, will have a squeezing effect on oil consumption, thereby reducing the fast growth in the number of motor vehicles on air pollution.
