Abstract:
It is a common phenomenon that absorption of solar radiation increases the temperature of photo voltaic cells , which results in a decrease of efficiency . The objective of this research is to decrease the cell temperature in order to increase the electrical efficiency using cooling system. This cooling system has been developed based on water spraying on PV panels . About 3-4 % efficiency increment has been found in the PV panel with cooling system against the PV panel with no cooling. It has been also found that the average power output increment is about 20% per each panel.
