This study is mainly to set up a photovoltaic (PV) test equipment for the PV efficiency measurement under the different inclination of PV panel. Solar radiation is simulated by the adjusting the halogen bulb to form the photovoltaic I-V curves. Due to the solar PV is a diode, solar energy will be converted to electrical energy and solar cell generates electrical power to supply the load we need, and therefore this experiment in different radiation exposure and different incline angle of PV panel are tested. Radiometer is used to measure the radiation values. The surface temperature of PV panel is also measured to compare and analyze the efficiency data of the different inclination.
