Abstract

The objective of this paper is to design and analyze a naturally ventilated photovoltaic-thermal (PV/T) air collector numerically and experimentally in both glazed and unglazed conditions. To reduce the panel's temperature, a thin metal sheet in the middle of the air channel is used to improve thermal and electrical output of the system. A good agreement is first achieved between the numerical results and the measured data. The validated model is then used to evaluate the effective parameters i.e. solar radiation intensity, channel depth and channel length on air mass flow rate, PV cooling, outlet air temperature as well as thermal and electrical efficiencies. The results show that while the thermal efficiency ranges between 12.21-37.17% throughout the day, the electrical efficiency ranges between 3.23-8.12%.
