One of the most important difficulties in using photovoltaic systems is the low energy conversion efficiency of PV cells and, furthermore, this efficiency decreases further during the operational period by increasing the cells temperature above a certain limit. To increase the efficiency of PV systems during operation period cooling systems are employed in the experimental work, three cooling systems: film water cooling, direct contact back water cooling and combining film - back cooling are presented and analyzed. The Infrared Camera used to obtain the module surface temperatures distribution. Experimental measurements for the three cooling experiments indicate that the temperature of the cooling photovoltaic module is lower up to 16, 18, 25 ºc for film cooling module, back cooling module and combined film – back cooling module, respectively compared to noncooling module. Reducing the module surface temperature causes an increase in module output power and module efficiency. The results show that the daily output power of the PV cooling module increased up to 22 %, 29.8% and 35% for film cooling, back cooling and combined film – back cooling module, respectively compared to non-cooling module.
