Improved power output of PV system by low cost evaporative cooling technology

This paper investigates, experimentally, the temperature dependence of performance of the solar panel. The panel performance is determined by short circuit current (I
_sc
), open circuit voltage (V
_oc
), fill factor (FF) and efficiency (□). The voltage and current characteristics of photovoltaic system is highly influenced by temperature. In order to increase the degree of electrical conversion to diminish heating effect, it is useful to decrease the module temperature. The power output of solar PV system improved by water based evaporative cooling technology without disturbing solar insulation fall on it. The increased efficiency is 10%.
