Polaris solar PV net news: (reporter Wang Shasha) on December 28, the official notice of the national development and Reform Commission in 2017, photovoltaic one to three categories of resources to new benchmark of new power stations price adjusted to 0.65 per kilowatt hour, 0.85, 0.75 Yuan in 2016, down 0.15, 0.13 Yuan, 0.13 Yuan, respectively. Although the official notification was not distributed, but in the interpretation of the price clearly distributed in photovoltaic subsidy does not adjust, proceed to 0.42 Yuan per kWh up standards in the country. This means that policy continues to guide distributed ground station than subsidy cuts in succession, country, fill, fill overlay fill, and even distributed PV counties make up “money scene” more attractive.
For now, of course, distributed PV in China is still seeking a mature business model, slow the development process, and to beware of a lot of impact on power grid. Solid in Jiangsu Dewei power technology Corporation General Manager, min, along with the falling cost of storage, distributed PV + energy storage will become the future mainstream form.
Distributed PV focus returns
According to the national development and Reform Commission, the National Energy Board had previously released the power development “Thirteen-Five” programme, the “Thirteen-Five” period, distributed PV scale in China is more than 60 million-kilowatt, that is, each of the next five years will be about 10 million-kilowatt distributed machine.
Market vision to realize key benefits. “PV ˙ science and technology ˙ the future” Forum, the new dimensional intelligent power engineer Wang Shujuan, distributed PV project benefits and policies, quality, safety, cost and energy efficiency are at stake, especially as policy-oriented industry, pricing policies around the PV project direction.
Distributed solar projects are “spontaneous use, more than power” and “full Internet” mode. Spontaneously their own price (Yuan/degree, the same below) = base price +0.42+ local subsidies, over power price = desulfurization of coal-electricity price in the local +0.42+ local subsidies; and the full price is benchmark price.
Shujuan Wang introduced, according to the market-based price minimum is about 0.5 Yuan, up to 1.5 Yuan, desulfurized coal-electricity price of 0.25~0.45 Yuan, then spontaneously use receipts =0.5~1.5+0.42+ local =0.92~1.92+ local subsidies subsidies, the more power return =0.25~0.45+0.42+ local =0.67~0.87+ local subsidies subsidies. By this calculation, 2017 “spontaneous use, more than power” mode income is clearly higher than that of full Internet access 0.65, 0.75, 0.85 Yuan/degrees, gradually eastward bias that explains solar pattern distributed the root cause.
Full Internet access, compared with solar subsidy cut, and leave light risk to project, Wang Shujuan stressed that “spontaneous use, more than power” mode of distributed PV project risk is low, mainly because user electricity price cut, and charge problems faced by industrial and commercial projects, high-credit users will compete for the object.
Electricity price subsidies, photovoltaic equipment, PV system design, proper operation and maintenance is the key to protection distributed PV projects.
Storage value dependent on cost reduction
Distributed outside storage industries is recognized as the industry’s other big potential markets. Starting from the second half of 2015, PV inverters in particular enterprises have started to raise energy. This area is photovoltaic power output of large stochastic volatility, reliable grid energy storage system on the other, with open electricity market reform in power, photovoltaic grid-connected and added storage will not only solve problems and build new business models.
BYD introduced daixiangjun, Director of product development for energy storage, 2024-storage system investment in 2016 will be increased on the basis of 6 times to $8.2 billion, global storage system capacity will be about 45 million-kilowatt. Energy storage device’s core market of the future will be Japan, and India and the United States, China and the five European major markets that account for 71% of global energy storage devices by 2014.
“However, prices do not accept it, value is not reflected. Energy storage industry is at this stage. “Germany TÜV Rheinland Group greater China General Manager Li Weichun said.
And observations from the international market, battery storage with the roll out of home market in rapid decline. Media reports in Australia, “PV + Tesla batteries + power” supply cost is slightly lower than from grid electricity purchase with “solar + energy storage” can basically meet the demand.
Lu Jinjun, Deputy Director of solid Dowell Research Center pointed out that household storage system within Germany, and Japan and the United States, and Australia and other markets developed rapidly, except that it can save electricity, a main driving factor is subsidies.
Focus on the domestic market, Lu Jinjun family of six villas in Beijing as an example, if Wei energy storage devices, equipped with solid +SEMSHome home energy management system, can save electricity more than 3,400 Yuan a year. In his view, with the opening of electricity markets, distributing + storage advantages will be more prominent, broke out looks forward to future energy storage in support of national subsidies.
