At present, Japan is 21 new coal project planning, development or construction, it is understood that their comprehensive capacity of 11 gw. 'Photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, photovoltaic stents what factory lead acid in lithium battery scheme can meet the needs of different readers. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development, solar photovoltaic (pv) network statement: this information is reproduced from the power grid cooperation media or other Internet website, solar 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. Solar heating of the heat storage but the report warned that if the Japanese government to recognize line a new coal project of some of these may be doomed to shut down in advance, and be stranded assets. The article suggested that Japan should now for each set of development or construction of coal-fired units are retirement plan, which avoids giving up project during the design life due to the high cost, thereby protecting energy consumers. The international renewable energy agency ( 国际可再生能源机构) The latest statistics show that by the end of last year, Japan's total solar power generation is 55. 5 gw, including 6 gigawatts of new facilities in 2018. Solar photovoltaic net news: recently, the photovoltaic stents what manufacturer financial think-tank carbon track plan joint at the university of Tokyo in Japan published 'the land of the rising sun and sea wind' ( 升起的太阳和海上风力) Report, China pv BBS, according to the report as renewable energy costs continue to fall, late in 2025, the solar heating of the heat storage will hit Japan's latest investment in coal. The article content is for reference only. , a research firm based in Tokyo RTS Corp recently published, according to a report by 2030 Japan's output will reach 150 gigawatts. The authors also predict that by the end of 2023, the leveling of pv KWH cost ( LCOE) May be cheaper than new coal facilities. Offshore wind is expected to reach that level in 2022, and onshore wind will achieve this goal in 2025.
