Under the influence of haze, the concentration of fine particles (PM2. 5) in the atmosphere is higher, which makes the direct radiation of solar energy lower and the scattered radiation increases. Therefore, the irradiance received by the surface of the photovoltaic module is reduced. The existing power generation estimation formula should be revised, hence a new formula for estimating power generation is proposed with the error range ± 5% from the actual power generation. Moreover, this paper explores the effect of PM2. 5 concentration on irradiance, irradiation and power generation. Through a photovoltaic roof test in a household in Shanghai, the irradiance control variable method and similar day principle are used to analyze the irradiance loss and power generation loss caused by PM2. 5, and to fit the relationship between them. At the same time, the concept of photovoltaic power generation loss index is proposed, which provides reference for the installed capacity of photovoltaic system and the reliability of photovoltaic system in the future .
