Effects of Rooftop Photovoltaics on Building Cooling

Abstract. Photovoltaic (PV) panels are commonly used for on-site generation of electricity in urban environments, specifically on rooftops. However, their implementation on rooftops poses potential (positive and negative) impacts on the heating and cooling energy demand of buildings, and on the surrounding urban climate. The adverse consequences can

Shading effect and energy-saving potential of rooftop photovoltaic

In the absence of photovoltaic (PV) panels, the heat absorbed by a cool roof (characterized by high reflectivity) is reduced by 65.6% compared to a conventional roof (with low reflectivity). However, once PV panels are installed, the disparity in heat gain between roofs with varying reflectivity levels is narrowed to approximately 10%.
