Solar energy is one of the cleanest, environmentally friendly and abandoned available sources.
 While photovoltaic (PV) module converts this free in form electrical energy, the
 efficiency PV reduces as temperature rises above nominal value. The
 Photovoltaic Thermal (PVT) system removes wasted thermal from surface which caused
 by reflection sun's irradiance stores it for u...
