Effect of temperature on solar photovoltaic panel efficiency

Abstract

Solar energy is the important energy source for future. Lot of devices are used for capture the energy from solar radiation and convert into useful form of energy. Solar PV (Photovoltaic) Panels are the promising devices convert the solar radiation into electrical form of energy. The partial portion of solar energy may be converted into electricity remaining in the form heat energy. Solar PV panel performance varies with temperature increase. The PV panel temperature has effect on power and voltage. Due to increase of temperature, the photovoltaic solar cells efficiency may be decreased. The life of the panel also will be decreased. In this paper how the heat energy received from solar radiation in the form of temperature affect the solar panel efficiency was analysed by experiment conducted with solar PV panel of 50W in the real outdoor environmental condition.
