This research studied temperature reduction of Polycrystalline silicon photovoltaic panel with the cooling module installed at the back panel. Serpentine channel and 45° V-shaped rib turbulators were attached inside the cooling module for enhance heat transfer ability. Water flow inside the cooling module will absorb the accumulated heat in the PV panel and produced hot water for usage. This design was called Photovoltaic/Thermal or PV/T panel. In this experiment, electrical, thermal efficiencies and net energy which produce by PV/T panel were evaluated and compared with normal PV panel at the real conditions for water flow rate of PV/T system are 0.5, 1.0 and 1.5 kg/s. The results showed the electrical and the thermal efficiencies of the PV/T were 14.20-14.90% and 40.70-44.30% respectively and more electrical power than PV panel about 13.97%
