Dust effect on the performance of the hybrid PV/Thermal collector

In order to study the effect of the dust on the thermal and electrical performance of the hybrid solar collector, a PV/T collector was designed and manufactured. The result showed that the dust effects largely on the performance of the hybrid solar collector. The results showed the thermal efficiency decreased 13.4% in case of dust existence on the outer surface of collector. Also, the highest electrical efficiency in case of clean collector was (10.24%), whereas the highest electrical efficiency in case of dust existence it was (5.67%). Also, the total efficiency of the hybrid collector was decreased by 17.5% for the dusty collector comparable with the clean collector.
