Abstract

Among the factors affecting solar panels, the amount of cloudiness, wind speed, temperature, latitude, and longitude can be considered. The purpose of this research was to estimate the amount of cloudiness and its effect on the passage of the sun's rays as well as to obtain the efficiency of solar panels in some cities of Iran from different climates; of course, the effects of temperature and wind were also investigated. For this purpose, four cities of Shiraz, Zanjan, Hamedan, and Abbar were considered.The estimation of the amount of cloudiness that affected the voltage, current, and power of the panel was obtained by checking the thickness of the cloud in different layers of the sky. The calculation of radiation emitted on the surface of the panel was undertaken using the Inishin model in PVLib Python software. The effects of cloudiness on the output power of the panel were investigated for each city. According to the results, wind speed and cloudiness, in addition to the effect of temperature, have crucial role in the output power of the panel, even in places where the cloudiness is above 80%.
