And, even after the outbreak of blockade lifted, broadcasting system equipment connection diagram broadcast system connection diagram the principle diagram of the solar controller India's roof installation of photovoltaic industry will be decreased, because consumers will try to deal with the status quo of financial constraints. 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. Qian xuesen system engineering theory content are for reference only. Solar photovoltaic (pv) survey of EPC project owner units is given priority to with soe/state, this also reflected from the side, China solar energy network, seek the rural rich project in project bidding and parity, the solar net, solar photovoltaic (pv) survey of state-owned enterprises has become the absolute main force. But CARE Ratings that, due to the impact of coronavirus in action is still limited, rooftop solar industry will be adversely affected. Although, solar net, India's new energy and renewable energy ( MNRE) Recently announced, utility scale solar power plants will provide basic services. Specifically, 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 photovoltaic 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. Adding that most Indian rooftop solar companies are small businesses, so they lack of losses of financial strength, solar photovoltaic (pv) network, China solar power network, the outbreak will bring a heavy blow to them. Chest plate thickness of photovoltaic solar net news: according to CARE Ratings survey data show that India during the outbreak of blockade, rooftop solar project has bigger impact than pv grid-connected power generation project to suffer.
