Abstract
Irrigation on upper surface of the PV panels is one of the most effective methods to reduce the operating temperature and to increase the PV power. Although there are publications about this technique, there is little information about the effect of the time and irrigation flow variations on the PV performance. This article presents an experimental study about the effect of both factor for a PV panel of 255 W installed in an warm – tropical place. It was found that flows of 4.5 l/min o higher can produce increases up to 10% in additional generated energy per day; in addition, irrigation time has a significant influence on the average operating temperature decreases and additional generated energy per day.
