2018 photovoltaic & other; 531' After the New Deal, shenhua huarong project 2019 solar manufacturers decline in demand in the domestic and industry into the winter period. Subsidies TuiPo, policy guidance, photovoltaic parity trend, the boom of photovoltaic industry history industry gradually recovered. Wind power projects but since 2019, the government pay more attention to the stable development of photovoltaic industry in our country, has issued a series of policy document; Advice to focus on crystalline silicon growth leading jing sheng mechanical and electrical equipment, photovoltaic slicing machine computer numerical control, photovoltaic battery equipment bibcock of jie jia weichuang, silk screen printing equipment leading Wallace for the stake, photovoltaic (pv) leading to his laser laser processing equipment, photovoltaic modules leading jinchen enterprise shares, etc. This paper not only includes editor Wolfgang & middot; Dr Parr, himself in his new energy career, more than 50 years of photovoltaic power station operation center to 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 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 web site, solar photovoltaic network published the article for the purpose of the information, engineering solar manufacturer does not mean that agree with his point of view or confirm its description. The article content is for reference only. Solar photovoltaic webex: dongguan securities, said the rapid development of photovoltaic industry, photovoltaic power generation and installed capacity is the highest in the world. Photovoltaic industry history, 'pv' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, shenhua huarong 2019 can meet the needs of different readers.
