Investigation of the Effect of Physical Factors on Exergy Efficiency of a Photovoltaic Thermal (PV/T) with Air Cooling

Thermal photovoltaic systems are used to harness solar energy generate electricity and thermal at the same time. In this technology, electrical efficiency is very low compared efficiency; as cell surface temperature rises, decreases, so one of ways achieve high exergy analysis. Exergy analysis a process or system shows how much ability perform work input has been consumed by that system. research, an ordinary panel with air cooling examined for exergy. To do this, it identified effective performance variables from mechanical point view, which inlet temperature, flow, length (number modules connected in series). The effect changing each based on Saveh weather conditions simulated using MATLAB software. results show decreases increasing. It was also observed optimal airflow 0012 (kg/s) will have highest per 8.8 m length.
