Performance Evaluation of 10 kWp Photovoltaic Power Generator under Hot Climatic Condition

This article presents the performance of 10 kWp photovoltaic power generator (PVPG) during 6 years under hot climatic condition. The PVPG is installed in 2005 at Energy Park, School of Renewable Energy Technology (SERT), Naresuan University, Phitsanulok, Thailand. This system consists of 3 PV technologies; Amorphous Silicon (a-Si), Poly Crystalline Silicon (p-Si), and Hybrid Silicon (HIT) with monitoring system to meet the guideline of IEC 61724. All of the important parameters are recorded from June 2005 to December 2010, which were used in evaluation processes. The results of this research found that the highest average array yield (YA) of a-Si, p-Si and HIT are 4.86 h/d, 4.36 h/d and 4.60 h/d, respectively at reference yield 5.27 h/d. The average array efficiency ηA) of a-Si, p-Si and HIT are 5.89%, 10.59% and 13.41%, respectively. a-Si has highest average annual array performance ratio about 0.92%, HIT 0.87% and the lowest is p-Si 0.83%.
