For more information visit NTRS News. Effects of Solar Photovoltaic Panels on Roof Heat Transfer Building Heating, Ventilation and Air Conditioning (HVAC) is a major contributor to urban energy use. In single story buildings with large surface area such as warehouses most of the heat enters through the roof.
Energy Savings Rooftop solar PV's contribution to buildings, especially in harsh climatic conditions, is through not only the generated power but also the shading effect to the roof surface. In hot climatic conditions, incident solar radiation on roofs significantly add to a building's cooling load.
Consequently solar PV has indirect effects on roof heat transfer. The effect of rooftop PV systems on the building roof and indoor energy balance as well as their economic impacts on building HVAC costs have not been investigated. Roof calculator models currently do not account for rooftop modifications such as PV arrays.
PV panels on a building's roof can help cut the cooling load by providing a shade to the roof blocking the direct penetration of solar radiation to it. Energy saving in the studied villa due to the shading effect of PV panels has been modeled with the help of EnergyPlus.
The study analyzed the impact of natural convection, roof energy balance disrupted by panels, and comprehensive conversion efficiency affected by temperature on two photovoltaic roof designs and compared them with a traditional roof.
Finally, a quantitative method for evaluating the comprehensive potential for energy savings is proposed, considering the electricity generation gain of photovoltaic panels and the comprehensive energy-saving efficiency of photovoltaic roofs, which generates a total potential for energy savings rate of 61.06%.
