Solar photovoltaic surface cooling using hybrid solar chimney-collector with wavy fins

Elevated temperatures, frequently observed in regions characterized by high ambient heat, markedly diminish the operational efficiency and curtail the lifespan of Solar Photovoltaic (PV) panels. Consequently, it is essential to enhance the sustainability and operational performance of solar energy s...

Civil engineering (General) Elevated temperatures, frequently observed in regions characterized by high ambient heat, markedly diminish the operational efficiency and curtail the lifespan of Solar Photovoltaic (PV) panels.
