Abstract:

In order to promote the development of photovoltaic （PV） generation, the government of China has promulgated a series of preferential policies such as price subsidies. Under the current price subsidies policies, PV generation enterprise can realize the profit, but it should consider national economic development to judge whether these subsidies are reasonable and sustainable for the country. Considering various influence factors of PV generation projects, the corresponding calculation model was established for the national economic costs and benefits, the economics of PV generation projects were evaluated by using national economic evaluation methods, and the influence of each main factor on the national economy of PV generation projects was quantitatively analyzed by using sensitivity analysis method. The evaluation results show that at present, the national economy of PV generation in some areas of China is still unreasonable. Finally, this paper proposed some optimization suggestions for the development opportunity and route of PV generation.
