Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, in project bidding and parity, the state-owned enterprises have become the absolute main force. Under the condition of existing technology, made in 100 mw production line perovskite photovoltaic components manufacturing costs are expected to be less than 1 RMB/W, mass production, the working life of the components will reach more than 25 years. 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. Such low component costs, storage battery means that the cost of pv systems will be lower than 3 yuan /, the cost of photovoltaic power even in eastern China are significantly lower than thermal power. According to field staff, 10 mw pilot production line made of perovskite photovoltaic modules for 45 cm * 65 cm, the photoelectric conversion efficiency reached 15. 3%. Specifically, the solar energy water heater controller of 603 mw, guangzhou guangdong nuclear development of 410 mw, 345 mw in energy saving, plate heat exchanger model parameters can jin group, 220 mw, the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mw photovoltaic net news: on November 7, 2019 9, China ( Wuxi) International new energy conference and exhibition 'held in wuxi taihu international expo center, plate heat exchanger model parameters at the scene to see the exhibition this year compare & other; Hot & throughout; ! ! ! ! When the capacity to expand to more than 1 gw, perovskite component manufacturing costs will also be further reduced to 0 per watt. 7 yuan. This is the most widespread worldwide perovskite photovoltaic components, is also a large area of perovskite module efficiency highest value. Is the construction of 100 mw production line m, the principle diagram of the solar controller components photoelectric conversion efficiency could reach as high as 18% above. The ideal heat
