Effect of Humidity on the PV Performance in Oman

Abstract- This paper presents the effect of relative humidity on the performance of the Photovoltaic (PV). Three types of PV (Polycrystalline, Monocrystalline and Amorphous Silicon) have been tested to investigate the effect of humidity on the performance. PV system connected to measurements humidity, current and voltage. Results obtained show that the output current, voltage, and power increase with low relative humidity. The efficiency of the PV is high when the humidity low. Hence low relative humidity enhances the performance of PV systems. I
