Thermal photovoltaic systems are new systems designed to reduce the temperature of a photovoltaic cell and to increase its productivity and utilize heat removed in other applications. In the present study, practical experiments were conducted to evaluate the performance of the thermal photoelectric system and to study the atmospheric effects (temperature and solar radiation intensity) on the system in the conditions of the city of Baghdad, Iraq. This city is characterized by high radiation intensity up to the maximum in August of summer (880 watts/m2) and this intensity is very high and close to the Solar Belt countries. A commercial polycrystalline PV module was used to make the PV/T collector. The test results show that the studied PV/T solar collector can provide good thermal efficiency. This study introduces the concept of primary energy efficiency to evaluate the PV/T system.
