  • Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions

    Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...
