Solar photovoltaic (PV) power generation is an attractive technique to reduce consumption of fossil fuels and as a renewable energy. PV system is convert photo energy into direct-current energy. The temperature of PV modules increases when it absorbs solar radiation, causing a decrease in efficiency. The overall power output and efficiency of the PV module can decrease by ~0.5%/ C and ~0.05%/ C when the ambient temperature of module increases. In fact the efficiency of the general PV modules is only between 13% until 20%. This caused will affected the PV module lifespan. In this work, the performance of PV output power is analysis by using PVsyst software. The open-circuit voltage (V oc ) of PV module, short circuit current (I sc ) and every change temperature on PV module are measure and record. In this work, the result of efficiency of PV under cooling system is 14% while the efficiency of PV under without cooling system is 10.3%. The incident irradiance is 1000 W/m 2 , the efficiency of PV module is 13.05% while the incident irradiance is 200 W/m 2 , and the efficiency of PV module is 10.45%. The higher efficiency of PV cell, the payback period of the system can be shorted and the lifespan of PV module can also be longer.
