According to the current laws and regulations, once the German photovoltaic cumulative installed at gw (52 Is expected in 2020 will reach) No longer enjoy subsidies, photovoltaic (pv) project. 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) net news: according to the German government's plans, will be closed all the nuclear power plant in 2022, 2038 years ago to gradually stop coal power plants. Magnesite brick heat storage technology at the same time, the scale of the energy storage needs from the current one. 9GWh( 1. 9 million KWH) Increased to 59 GWH ( 57 million KWH) 。 The article content is for reference only. According to consultancy EuPD research, in order to meet future demand for German electricity, photovoltaic total installed need to Germany in 2040 to reach 252 gw ( 126 gigawatts of large ground photovoltaic, monitoring, battery low power industry distributed photovoltaic 91 gigawatts, residents photovoltaic roof 35 gw) 。 'Photovoltaic (pv) of the world' this is a comprehensive system to introduce the development of photovoltaic (pv) in the past, solar photovoltaic products used now and the future the sum of the corpus, wide-ranging, solar water can meet the needs of different readers. Photovoltaic (pv), for example, the current total installed in Germany about 48 gw ( 16 gigawatts of large ground photovoltaic (pv), industrial and commercial distributed photovoltaic 24 gigawatts, residents roof photovoltaic 7 gw) 。 So how much renewable energy generation, the need to make up the gap? 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. In order to achieve this goal, Germany needs to re-examine subsidies for solar photovoltaic TuiPo mechanism.
