Impact of Temperature on the Effectiveness of Solar Photovoltaic Panels

The present study finds out the power output and efficiency due to temperature increase by experimental method. Future energy sources will largely come from solar energy. Many devices are used to collect solar energy and transform it into usable forms of energy. The promising technology for converting solar radiation into electrical energy is solar PV (photovoltaic) panels. 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. Additionally, the panel's lifespan will be shortened. This study used an experiment with a 50W solar PV panel in a real outdoor environment to examine how heat energy from solar radiation in the form of temperature affects the efficiency of solar panels.
