Abstract
The aim of this paper is to examine the major impact of cell temperature on the performance of the monocrystalline module under Derna City climate conditions. A mathematical model was developed to estimate cell temperature where the method of energy balance is applied using meteorological parameters such as ambient temperature, slope radiation, and wind speed. The experimental measurements were conducted for a particular day of October 2019. The validation of the calculated results was performed by comparing the attained results against the measured cell temperature of the module. It was observed that the cell temperature, slope irradiance, and electrical power output from the PV module reach their highest at 11:30, with values of 64.7°C, 968 W/m,2 and 47.73 W, respectively, whilst the ambient temperature was found to be 36°C. The energy balance method that was presently deployed was highly successful in identifying the cell temperature; hence, promising results of fitted parameters were of significance, as the coefficient of determination (R2) = 0.9996 and the root mean square error (RMSE) = 0.582.
