Abstract

Studies realized on the performance of photovoltaic modules have shown that analysis of the effect of meteorological parameters is crucial in prediction and evaluation of performances; and production of solar systems. This paper highlights the performing analysis of a monocrystalline silicon photovoltaic module. The aim of this work is to study the effect of irradiance and temperature on module performance in a real environment. The variation of the exergy efficiency as a function of the module temperature on a day is presented. The electrical exergy rate and the thermal exergy losses rate of the module were examined. The findings of this study show that the exergetic efficiency depends on the variation of the irradiance and temperature during the day. Results give an exergetic efficiency of the module varying from 14.87 to 17.93% per day for monocrystalline 30 Wp PV module. The results also show a variation of exergetic efficiency for the same irradiance and decrease in efficiency with increasing module operating temperature. This decrease is 17.5% for an increase of 10   (irradiance = 900 ). The thermal exergy losses rate increases with the difference between the module's operating temperature and the ambient temperature. It reaches its maximum (3.36 W) for a temperature difference equal to 28.9 K.
