Evaluation of the performance of the photovoltaic Trombe wall in the Iraqi conditions

Abstract

An experimental study was conducted to assess the impact of cooling technologies on the performance of the PV/Trombe wall system. The solar panel's cooling system included a DC fan. and the water passing through the heat exchanger installed behind the photovoltaic panel was used. The results showed that in the case of using water and air cooling, the temperature of the photovoltaic panel decreased, reaching (25.60°C) at 12 p.m. The electrical efficiency was recorded as its highest value when employing water for cooling, as it reached (13.75%). As for the thermal efficiency, it reaches its highest rate employing air and water for cooling due to the thermal energy gained by water and air, as it reached (45.83%).
