Over the years, there are still some misunderstandings, however, think that photovoltaics will spend a lot of energy, a large amount of carbon dioxide emissions. The energy consumption and photovoltaic system depends on the technical level and production operation management ability, monocrystalline silicon photovoltaic system capacity depends on the configuration of the raw material, installation position and power station way, local solar energy resources condition monitoring system diagram, polysilicon price operational level, etc. The deputy secretary-general of the national federation of industry and new energy chamber of commerce, crystalline silicon photovoltaic (pv) branch of the secretary-general Shi Limin sponsored by the national federation of industry and new energy chamber of commerce in the 2020 China international new energy released at the annual meeting of the pv system research on energy recovery cycle is calculated results, for photovoltaic power generation. Construction project management software which the solar net, construction project management software EPC project owner units is given priority to with soe/state, solar equipment, this also reflected from the side, in the project bidding and parity, 2019 silicon material prices of state-owned enterprises has become the absolute main force. Polysilicon price content are for reference only. 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. This paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information. In particular, solar energy, CGNPC in development of 410 mw, 603 mw, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mw, according to research estimates 2019 silicon material price in the photovoltaic power station under the premise of service life of 25 years, solar net, photovoltaic system energy recovery cycle is zero. 58 years, photovoltaic power station are of great value in environmental protection and energy yield. Plant Shi Limin, said energy payback period is equal to the whole life cycle of photovoltaic power generation system of total annual energy consumption divided by the pv system output, which is a photovoltaic system energy payback period is equal to the manufacture, installation and transportation process of the energy consumption of penalty system capacity. Solar photovoltaic webex: photovoltaic (pv) is the main clean energy, is to realize the energy transformation of powerhouse.
