Do rooftop photovoltaic panels reduce indoor heat gain?

Rooftop photovoltaic panels can serve as external shading devices on buildings, effectively reducing indoor heat gain caused by sunlight. This paper uses a numerical model to analyze rooftop photovoltaic panels' thermal conduction, convection, and radiation in hot summer areas as shading devices.

Why do photovoltaic panels increase roof temperature?

The shading effect of the photovoltaic panels makes the roof temperature in the shading area higher than that in the unshaded area. This is because the photovoltaic panels store a certain amount of heat during the day when the irradiation is abundant, radiating heat with the shading area at night, causing its temperature to rise.

Do solar panels reduce heat absorbed by a cool roof?

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%.
