KennethWa Rnmark looking for alternatives to expensive metal for a long time with our colleagues, and will focus on the iron, because the iron in the crust of prevalence rate was 6%, easier to obtain. Before, they develop the iron base molecules, have proved their potential in solar energy application in research.
solar photovoltaic net news: on January 22, 2019 pv subsidy policy at the National Development and Reform Commission, the exchange meeting again, according to the participants of the enterprise and media reports, 2019 households with photovoltaic subsidies for basic at 0. 18 yuan/KWH. , according to a report in the pv the door with photovoltaic (pv) more than full access to the Internet and electricity web part, subsidies in accordance with the local coal feed-in tariff + 0 benchmarking. 18 yuan/KWH to calculate earnings.
and formulate policy accordingly, desulfurization of coal price benchmarking, whether residential electricity have JieTiXing and the effective number of sunshine hours will be gains the decisive factors in geometry. According to the Chinese photovoltaic industry association released & other; 2018 edition of China pv industry development roadmap & throughout; , we can determine a set of basic household photovoltaic probably cost price, as shown in the figure below:
remove part of the cost required for the industrial and commercial distributed, 2019 years to build a set of household photovoltaic (pv) the cost of the price as follows: 0. 25 + 0. 27 + 0. 49 + 0. 23 + 0. 23 + 1. 68 = 3. 15 yuan/W. But because do not have mass, dealers with the price must be higher than 3. 15 yuan/W, according to the communication consulting, the vast majority of the dealer's stock price in 3 ~ 3. About 5 yuan/W. Foreign sales price according to the regional, probably the interval of 4. About 5 ~ 6 yuan/W, for the convenience of calculation, we unified planning its price is RMB 5 / W.
according to these data, 5 yuan/W household photovoltaic, at 0. 18 yuan/KWH of subsidies, the yield of the provinces, and cost recovery period can be made into the following form:
note: 1, the form output data from the national federation of industry and new energy chamber of commerce and longji jointly published by the knowledge of distributed photovoltaic assembly manual;
6, for the convenience of calculation, the province is not included, through forms the source file have a province to fill the place to change the relevant numerical according to the province to fill situation;
7, according to the national grid of money [2014] no. 1515, household photovoltaic (pv) shall be exempted from VAT, but south net to pay tax, this form does not contain electricity price of taxes and fees;
by form of data calculation, we can see that in the north of household photovoltaic most yield about 10%, in the southern region is about 8%, chongqing, guizhou and other places are not suitable for basic household photovoltaic (pv). From the point of cost recovery period, is maintained at about 6 ~ 7 years, individual have a province to fill the region could be reduced to 5 ~ 6 years.
the form data do not have uniqueness, size and installed cost darned, province, provincial price cycle, residential electricity price, the total generating capacity of 25 years and spontaneous self-used rate are adjustable. In positive case, when installed cost reduced to 4. 5 yuan/W, spontaneous self-used rate reaches 50%, the yield in most of all reached more than 10%.
through several form contrast, we may safely draw a conclusion that, in 4. 5 ~ 5 yuan/W of installed unit price range, 0. Year of yield of 18 yuan/KWH subsidies with 6 yuan/W, 0. Year of yield of 32 yuan/KWH subsidies basic no gap. In security door system on the basis of quality and after-sales, 5 yuan/W within the household photovoltaic can still carried out a lot.
as the table data is adjustable, user to all dealers and potential customers can be obtained through the adjustment of the variable data in a table in the local annual return and specific income 25 years; At the same time, through the recovery cycle count adjustment first power generating capacity in the table, the desulfurization of coal electricity price, size, and the installed unit price benchmarking values, such as according to & other; IF the function & throughout; It is concluded that value cost recovery cycle.

on January 28th in the morning, the National Energy Administration, at a news conference in Beijing issued 2018 renewable energy grid operation. New energy and renewable energy division, deputy director of the chuang-jun li overall train of thought on the development of photovoltaic power generation in 2019 questions from the journalists. Reporter: we have noticed that in 2018 the national photovoltaic new power scale hit a record high 2, 2019, the overall idea of the construction of photovoltaic power generation is what? Chuang-jun li: after a few years
