Experimental examination of a thin-film photovoltaic panel power characteristics under constant load during October-March period in Mersin province

In this study, the power generated by a thin-film photovoltaic panel was measured under real atmospheric conditions in Mersin between October and March. The experimental setup involves a stand with adjustable inclination around a single axis, current meter and voltage meter, pyrometer, and two computers on a mobile rack. The power generated was determined as a function of solar irradiance using the data recorded with three minutes intervals in each measured day, during the six months period. The average generated power, irradiance, and efficiency were calculated for each measured month using the data collected. The generated power and efficiency values are found to be different from that of the values provided in photovoltaic panel manufacturer specifications.
