摘要: In this paper we study and compare the environmental efficiency of 118 photovoltaic (PV) plants in China. Drawing on nonparametric data envelopment analysis (DEA) method, our takes initiative to take insolation, annual sunshine duration, covering area as input variables into account, well installed capacity, electricity generation, CO 2 emission reduction, coal saving output variables, provide a unified measure PV We find widespread inefficiencies roughly 95% plants, performance different economic zones types are quite different. Specifically, those eastern China least satisfying performers among three zones. The surprising result indicates that has room for improvement by overcoming caused serious aerosol pollution high urbanization rate. also rooftop have highest efficiencies four due very little power loss. However, complementary lowest most likely because operating temperatures during process generation.
