Impacts of air pollution and meteorological conditions on the generation efficiency of photovoltaic system in Xi’an, China

Abstract

In recent years, as a renewable resource, solar energy has been widely used and has bright prospects. Studies have shown that air pollution has a certain impact on photovoltaic power generation, but the quantitively influence of the impact factors is not clear. Though the analysis of experimental records of various air pollutants and meteorological factors, and calculation results of extinction coefficient and power generation efficiency, the main factors affecting photovoltaic power generation are determined quantitively.
