Low because of the increase in efficiency of the solar energy photovoltaic component installation costs, installation costs and preparation costs fell on the ground, this will reduce the need to prepare the ground for land area and per kilowatt of the required number of installed. In order to find out the cost of electricity per KWH, the author puts forward three kinds of scheme - - efficient, average and high cost structure And found that even in the same period began operations between power plants, power generation cost is also very big difference. ” Solar photovoltaic net news: according to Japanese solar power cost, by 2030, Japan's solar photovoltaic power generation cost could be from the current 15 per KWH. 3 the yen ( 0. $14) A sharp fall in to 5 per KWH. 00 yen to 6. 00 yen ( 0. $047 to 0. $056) Levels. The institute suggest change the policy level, to ensure that the system design followed the feed-in tariff subsidies ( 配合) Plan implemented under the solar set a time limit of the project, and suggest that regular checking power generation costs, shaanxi photovoltaic recruitment information network that will guide the government to take the right measures about decision of the country's future energy structure. Shaanxi photovoltaic recruitment information network, the researchers found that the module costs have fallen sharply, from 2017 to 2018, the hardware cost per kilowatt unit has fallen dramatically. The report says & other; If it can be developed for Japan's geographical characteristics of the design and installation methods and new management methods, is still has the potential to further reduce the cost. The report's authors warned that & other; But, the increase of the solar photovoltaic power generation on the market could lead to the overall market prices. This paper not only includes editor Wolfgang & middot; Parr, Dr Himself in his new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and the system summary, also include the global photovoltaic industry professionals engaged in new energy or review, through carbon tracking of photovoltaic difficult development initiative, a study at the university of Tokyo and CDP recently warned that Japan may be in the $71 billion in coal assets at the stranding, if these are not on time in the solar photovoltaic and wind power gain prominent retired. According to the report, even compared with the current daily average day average electricity market price, the price is cheap enough, it proves that even without subsidies, photovoltaic technology may also be a competitive price level. Solar photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. ” 'Photovoltaic (pv) of the world' this is a comprehensive system to introduce the development of photovoltaic (pv) in the past, present and future the sum of the corpus, wide-ranging, can meet the needs of different readers. Throughout China's green building &; “ To study the potential of solar energy photovoltaic really play a role of independent, need to consider the power supply and demand of the market analysis. Discarded silicon prices despite the huge cost of potential, but the reality is that Japan's solar power cost is much higher than the global level, at the global level, the cost of solar power usually have parity with fossil fuels, but by 2030, Japan has reached the anticipated cost level. Sun room on how to install photovoltaic nonprofit think-tank, renewable energy research institute. 'Japan's present situation and the future. ' Japan, and the price is the general concept for its massive management/interconnection cost. The boss 'son by softbank group (the institute Masayoshi Son) Founded on about 1676 solar pv power station operators were investigated, the investigation of the project capacity between 50 kw to 2 mw, on behalf of the cumulative capacity of 89 megawatts. Today there are many other countries. The article content is for reference only.
