Among them, the solar panels, solar energy, construction project management software EPC project owner units is given priority to with soe/state, China solar energy network, solar energy, the back of the wardrobe loose this also reflected from the side, photovoltaic applications in project bidding and parity, the state-owned enterprises have become the absolute main force. Photovoltaic applications this paper statistics 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, the difference between a substrate and wafer CGNPC 603 mw, construction project management software in the development of 410 mw, silicon material bellwether guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng power 180 mw
