Validation of Thrmal Models for Polycrystalline Photovoltaic Module Under Derna City Climate Conditions

The main objective of the present paper is to compare nine diffrent cell temperature models available in the literature with data measured under real Derna city climatic conditions (a semi arid climate) for month of August. Th study focuses on a comparison of nine theoretical models to calculate the cell temperature based on the experimental measurements such as the ambient temperature, irradiance, and wind speed in some of the models. Th presently used models are explicit, depending on the easily measurable parameters and of wide applicability. Six statistical quantitative indicators are used to evaluate the cell temperature models analysed, namely, R2, RMSE, RRMSE, MAE, MBE and MARE. The cell temperature correlations presently studied, fist order linear models depending on the ambient temperature, solar irradiation incident on the panel and voltage output, provide the most accurate cell temperature estimations at Derna city climatic conditions
