Agricultural photovoltaic PV Thirteen Five how important

Polaris solar PV net news: agricultural scale PV development problems are not solved, PV “Thirteen-Five” planning objective will be very difficult to achieve. Re-examine PV agriculture is not only a question of quantity, it is a quality issue.

National PV development “Thirteen-Five” planned power plant construction is 150GW, the growth of PV power station construction is 436%. Compared with other renewable energy “Thirteen-Five” power station construction targets double-digit growth, 436% growth is highest in the PV is inspiring.

But please wait for the PV “Thirteen-Five” cheer power station construction, because it probably can’t do.

PV is always surprising, the last more than 10 years, photovoltaic industry from scratch, from there to the world; the past four years, photovoltaic power plant construction from scratch and from there to the world. But it started two years ago, there was another accident.

The surprise is that by 2013, PV power station construction always not surprisingly higher than expected development results, after 2014, the PV power station construction below the planned target of the result is always unexpected. The 2014 plan 15GW, actual finish 10.6GW;2015-year plan 23.1GW actual 15.1GW.

There are several reasons contributing to this accident, PV results are not ideal for agricultural development must be one of the important reasons. PV scale development of agriculture-related issues are not resolved, will eventually become the PV development “Thirteen-Five” planning targets, and even the most important factor affecting China’s energy supply structure.


Agricultural photovoltaic PV

This is because, distributed PV PV development is “Thirteen-Five” important part of the planning, and important component of agricultural is distributed in photovoltaic solar power station. Large-scale photovoltaic development problems are not solved, distributed PV development “Thirteen-Five” target difficult to achieve, the PV “Thirteen-Five” planning goals more difficult to achieve, rationalization of the energy supply structure in China will encounter obstacles.

So, should stand on photovoltaic development “Thirteen-Five” point of view of planning, rationalization of China’s future energy supply, re-examine PV agriculture, this is not just a quantity issue, it is a quality issue. At present, the PV scale some problems need to be solved in the development of agriculture:

1. distributed has been past PV annual construction goals to finish the main reason

2014 15GW distributed PV power station construction goals, actual 10.6GW, distributed target is 8GW, only complete national PV power station construction is 2GW;2015 years 23.1GW, real 15.1GW, which distributed do not set goals, encouraging the development of actual 2GW. The actual construction of distributed PV results, seriously affecting the national PV power station completed annual construction goals.

Result was not ideal because of distributed PV power plant construction worth serious study. The past two years, the State distributed PV unprecedented attention, policy has never been favored, despite the bad results can predict distributed construction, but actual construction results is always worse than anticipated. These results force us to think seriously about the upcoming PV development “Thirteen-Five” program, how to locate distributed PV? How to develop distributed PV?

2. distributed PV development must be “Thirteen-Five” important part of the planning

In photovoltaic development “Thirteen-Five” in planning and discussion, two important indicators: goal 150GW is a photovoltaic power station construction, which distributed 70GW; one is a new solar power installed capacity of 35% in the Western region and other 65% located in the Central and Eastern regions. Often, people only remember the first, ignoring the second.

The connotation of these two indicators is the same, is the PV “Thirteen-Five” indispensable in planning, number of irreducible two data, must be simultaneously achieved. This is determined by two reasons:

Be decided by reverse distribution pattern of China’s energy resources. In China scale development PV power, has three species select: first, in solar resources, and can using land rich of West construction mass PV power station, will PV power mass, and far distance conveying to power load Center of East, its results must is conveying capacity limited, and conveying cost high, this must not optimal of select; second, in solar resources is not most rich, and but power load Center of East construction mass PV power station, although not need mass, and far distance conveying, The result would face severe shortage of available land, this is unlikely to be optimal choice; and, third, in the large-scale development of distributed PV power station in the East, will undoubtedly become the optimal choice, must be selected. Similarly, it has also become PV development “Thirteen-Five” programming option must be selected.

Another reason is the coming era of democratization of energy decisions. Distributed power of spontaneous use, elimination is the most reasonable energy use patterns, fast development of the smart grid, energy storage technology, the democratization of energy is possible. Compared to all other forms of energy use, only natural distributed in photovoltaic power of standard forms and the most economic use of the form, which is the main development direction of energy form beyond doubt. Similarly, that undoubtedly should be PV development “Thirteen-Five” planning important content.

3. PV of agriculture should become an important component of distributed PV

The connotation of distributed PV: refers to is located near the users, energy use, with 10,000 volts and the voltage connected to the grid, and the single and network capacity does not exceed 6 megawatts of power generation projects; extension of distributed PV power plant: mainly by roof power station (residential and commercial) and PV agriculture consists of two major parts.

PV agriculture should become the most important component of distributed PV. This is because, only to develop photovoltaic agriculture to complete photovoltaic development “Thirteen-Five” planned construction of distributed targets.

By the end of 2015, China has built a distributed PV 5.7GW, PV development “Thirteen-Five” planning to build 70GW distributed targets over the next five years, building annual amount cannot be less than 12GW. PV “Thirteen-Five” planning how distributed targets will form, how to realize the problem, and at how an issue will determine whether implementation issues.

Distributed PV development in China in the past has been proven, have to get rid of depends on the roof completed “Thirteen-Five” planning the rest of 62.3GW distributed PV power station construction goals, realize rational energy supply of the future body of fantasy. This is affected by population and the available land is scarce, limited building roofs, property rights complex effects determined by the roof couldn’t have had enough. And not only the existing roof difficult to satisfy for PV power station building, and that it cannot be required to meet the reasonable layout of PV.

Now that the roof does not resolve to achieve PV development “Thirteen-Five” planning, rational problems of energy supply structure, must re-examine, positioning – another extension of distributed PV agriculture. Based on the scientific and rational policy, agriculture should become an important part of distributed PV PV.

4. PV agriculture has become an important aspect of distributed

Photovoltaic meaning of agriculture: refers to the establishment of agricultural facilities or agricultural land, does not change the nature of land and promote agricultural and solar photoelectric and the comprehensive development of agricultural complex systems.

PV agricultural extension: include agriculture (plant breeding) greenhouses, agricultural complementarity and fishing light complement each other, Lin Guang to complement each other. Among them, the complementary extension of light: in the field of agriculture through scientific and rational raised mounting or flexible mounting scheme, agricultural cultivation without changing both fair value and photovoltaic power generation combined with a form of reciprocal basis.

5.7GW distributed PV power plant in China has completed digital, distributed PV PV agriculture has in fact become an important content. If you pay attention, lots on the development of distributed PV news and cases, a large proportion of all PV agriculture-related. A lot around distributed PV training and case, also related to agriculture and PV.

Recently Zhejiang Province NDRC Zhejiang agricultural light complementary type ground PV power station construction effectiveness, and exists problem and recommends a paper in the said: “as March 2016 end of, Zhejiang Province has built grid ground PV power station 20 a, total scale 672,000 kW, which including East provinces monomer scale maximum of are Thai jiangshan 200 MW agricultural light complementary ground PV power station; building 14 a, total scale 647,000 kW; is expected to 2016 end of province can built ground PV power station 2 million-kilowatt above. Photovoltaic power stations on the ground are used ‘ complementarity ‘, ‘ Yue Kwong mutual complement ‘, ‘ Lin Guang complementary ‘ mode, with multiple economic and social benefits. “Known by the end of 2015, total amount of photovoltaic power stations have been built in Zhejiang Province is 1.64GW.

5. the current policy does not explicitly affect PV to large-scale development of agriculture

Currently, the State of development of photovoltaic agriculture’s general attitude is positive. However, or under the influence of photovoltaic involve more cross-industry Management Department of agriculture, it administered. Or under the influence of cognitive approach varies, and inevitably related policies are not clear. Performance has three: in energy management sector, National Energy Council on further implementation distributed PV power about policy of notification clear proposed “encourages distributed PV power and farmers poverty, and new rural construction, and agricultural facilities phase combined, promote rural residents life improved and agricultural rural development”; in land management sector, land resources department development reform Board Technology Department industrial and information Department housing urban and rural construction Commerce on support new industry new industry State development promote mass venture peoples innovation with to of views clear proposed ” On the occupation of agricultural land for construction, all parts should be according to construction land management “; in the agricultural sector, it is understood because the support and opposition to two quite different views at the same time, currently in a State of wait-and-see and do not participate in. This makes photovoltaic agriculture, especially agricultural and light complementary development in a State of dilemma.

Carefully introduce PV agricultural policy is correct. Because of the “red line of 1.8 billion mu of arable land,” the national strategy issues should not be discussed; second, because the combination of farming with photovoltaic, and their efficiency is not affected, combining well, their benefits are affected. Third, because PV agriculture, business model is also of concern in the ripening process.

However, in order to complete PV “Thirteen-Five” planning distributed short-term development goals and rational energy supply structure of long-term development objectives, PV status of agriculture issues also to be expeditiously explore and solve when, in particular agricultural complementarity problems. This is because, agriculture greenhouses, fishing light complement each other, Lin Guang complementary utilization of space is limited, complementary use of space is enormous.

PV agriculture is the scarcity of agricultural land in national agricultural development and photovoltaic power generation development of a creative, is a last resort in the cause of human development of photovoltaic passive selection, its only value is in full use of land resources. Therefore, stressed that in order to develop photovoltaic agriculture, especially agricultural and light complementary logic: this is not the best choice, but probably should be selected.
