Description
Summary:The efficiency of solar photovoltaic (PV) power generation is significantly impacted by factors such as ambient temperature, surrounding wind speed, and the temperature of the solar PV panels. The power generation efficiency of these panels diminishes by approximately 0.5% for each incremental rise in their temperature. To mitigate this effect, two primary methods for cooling solar photovoltaic panels are considered: active and passive cooling techniques. This review paper delves into an extensive body of literature on solar passive cooling systems, highlighting the vital role of passive cooling technology in enhancing the efficiency of solar PV power generation. We investigate the structure and cooling effect of diverse passive cooling systems, with a specific focus on the application of solar chimneys and ventilators in cooling systems for solar PV panels. Our study reveals that solar chimneys, using buoyancy, can decrease the temperature of solar PV panels by as much as 15 degrees, thereby augmenting power generation efficiency. Furthermore, the deployment of ventilator technology can boost the efficiency of solar PV power generation to an impressive 46.54%. In conclusion, this paper proposes the synergistic use of solar chimneys and ventilators to improve solar PV panel efficiency, extend their lifespan, and reduce the environmental impact resulting from inefficient solar PV panels. This comprehensive approach should inform future practices.
