The air gap formed between the solar panels and the roof allows heat to dissipate through convection, further decreasing heat transfer to the building. This article explains how temperature impacts photovoltaic efficiency, compares cooling methods, and shares industry-proven strategies to maximize energy output. Mitigating energy demands in buildings will substantially curtail the required supply of energy and, hence, minimise greenhouse gas (GHG). . Solar panels are installed above the roof surface, creating a shading effect that blocks direct sunlight from hitting the rooftop. Panels convert sunlight to electricity, minimizing heat buildup on roof surfaces.
