Experimental study on the electrical performance of a solar

The decreased efficiency of a photovoltaic panel due to temperature rise during high solar radiation is one of the major drawbacks. The efficiency drop is due to hotness, which restricts the conversion of incident sun rays into electricity by the silicon cells. Thus, a photovoltaic panel has a negative temperature coefficient that increases the current but drops the voltage
