Effect of Temperature on the Solar Module Performances

Abstract

Photovoltaic system is established as a reliable and economical source of electricity in rural and Sahara areas, especially in developing countries where the population is dispersed, therefore requiring low energy consumption. Among solutions of producing decentralized electricity, the present renewable energies presents many advantages comparing to the classic sources (nuclear, oil, gas, etc). The solar energy is the most promising among other renewable energies and especially. for developing countries where irradiance is very strong (Arabian countries). The results, which are illustrated by curves, are analyzed. The analysis qf the performance concluded that this electrical parameters decrease with the temperature. A decrease of the output power (4 wIcK), of the open voltage (0.2 VI°C) and of the conversion efficiency (0.59 x10-3 % PK) of the PV module with the temperature increase has been observed. The current increases approximately linearly with the temperature with 1.2 mA PC.
