Abstract
ABSTRACT Urban haze has a multiple hazard in human living environment. It is not only harmful to human health but also affects the light passing through the atmosphere. This paper presents a study explaining the impact of haze on the performance of photovoltaic (PV) panels in the same humidity season. Using continuous and high-resolution on-site photovoltaic data from Shanghai, the paper calculates the attenuation of irradiance and the shortening of power generation hours due to changing concentrations of fine particulate matter. For Shanghai, we find that the relative loss of power generation was 14.09 MJ with loss ratio of 8.1% in total and the effective power generation hours were only 29.66 hours in the most serious air pollution month between December 2017 and February 2018. Economic damage from air pollution should not be ignored. Three economic models under the condition of haze are presented. The winter yield of the optimal economic model is 249.43 USD. Comparing the months with severe haze pollution and slight haze pollution, the revenue loss is estimated to be 59.17 USD. Meanwhile, the annual revenue without air pollution was estimated and the payback period was extended by 0.52 years due to the haze. This study has certain implications for PV installers and investors.
