Due to the spatiotemporal variability in the solar radiation on roof surfaces, it is essential to determine the potentials of the rooftop photovoltaics and its variations in specific regions. In Germany, this potential was assessed in 5 km × 5 km zones, as well as at the federal-state and national levels.
It serves as a valuable complement to other renewable-energy sources and is expected to play a crucial role in future electricity systems. Due to the spatiotemporal variability in the solar radiation on roof surfaces, it is essential to determine the potentials of the rooftop photovoltaics and its variations in specific regions.
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.
The rooftop PV potential was estimated to total 22,551 GWh. Therefore, the performance of the rooftop PV potential estimation method performs well. In this study, the solar radiation data are the global surface solar radiation (3 h, 10 km) which is more suitable for large-scale photovoltaic potential assessment.
The coupled heat transfer process of rooftop photovoltaic shading units and indoor heat gain are analyzed. The energy-saving potential of photovoltaic rooftops compared to traditional rooftops is revealed. The energy-saving performance of photovoltaic and traditional rooftops under different roof reflectivity are summarized.
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.
