Among them, the EPC project owner units is given priority to with soe/state, dual-computer hot for open source software and this is reflected from the side, in the project bidding and parity, solar portal, state-owned enterprises have become the absolute main force. Classification of photovoltaic applications in particular, solar energy equipment, 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 and wind power growth especially 328 respectively. 930000 mw, and 330. 330000 mw, 100 year-on-year growth. 82% and 68. 39%. The principle diagram of the solar controller solar photovoltaic webex: solar photovoltaic (pv) network, according to photovoltaic (pv) grid, recently released China power international development co. , LTD. 2019 sell electricity situation, as of December 31, 2019 year, 3 mm chest back the group wholly owned or holding power plants the merger of the total quantity sold about 8355. Rose 17 90000 megawatts. 75%; In the fourth quarter of 2019 the total quantity sold about 1861 merger. 570000 mw, rose 3. 1%. Dual-computer hot standby and thermal power, open source software hydroelectric power, photovoltaic application classification of the total quantity sold 2019, 5601 respectively. Schematic diagram of 2094 970000 megawatts, solar controller. 680000 mw, the growth of 9 respectively. 60% and 28. 87%. 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. The article content is for reference only.
