EXPERIMENTAL STUDY OF A RETROFITTED SOLAR PHOTOVOLTAIC THERMAL COLLECTOR SET AT A VERTICAL INCLINATIO
Renewable energy systems and their efficiency have major factors on building’s sector. This studyconcerns an experimental investigation of hybrid photovoltaic thermal collector, simulating a building integrated photovoltaic façade. The retrofitted solar panel ensured good electrical conversion efficiency with an average gain of 7% and 8.85% for the two optimal configurations compared to the conventional panel. Besides, the heat discharged from the cells preheats the airflow at rear of the panel resulting thermal efficiency of 60 to 70%. Amongst the tested configurations, two cases showed electrical and thermal efficiencies’ enhancement: lower power device in air extraction mode and higher power device for incoming air case.
