Abstract

Renewable energy is becoming more popular as an energy source as non – renewable energy sources become less prevalent. One of popular renewable energy that used is solar photovoltaic to generate electric energy. However, its efficiency reduced when its operating temperature increased with the increase of solar radiation. Therefore, a cooling system is necessary for solar PV. The aim of this study is to provide a passive cooling system using solar chimney assisted with wire mesh. In this study, it investigates the effect of wire mesh assisted solar chimney on performance of solar PV cooling in terms of power output, efficiency and temperatures of solar panel surface. The wire mesh assisted solar chimney was put at the outlet of solar chimney. Three test rigs known as configuration 1 (solar PV without cooling), configuration 2 (solar PV integrated with solar chimney as cooling), configuration 3 (solar PV integrated with solar chimney and wire mesh as cooling) were fabricated. The experimental conduction was carried out in the Faculty of Engineering, University Malaysia Sabah. The result showed that the effect of wire mesh in solar chimney has the highest increase electrical efficiency of solar PV which is 15.45% and has highest temperature reduction of solar panel surface which is 12.88%. The effect of wire mesh also showed that it can increase the flow rate of air inside the solar chimney, thus improved the ventilation of solar chimney. This is due to the higher buoyancy effect can be produced when air received more heat by restrict the flow rate at first by wire mesh. To conclude, wire mesh has helps in increasing the performance of solar PV setup cooling.
