Evaluating the comprehensive energy-saving effect of roofs
This model integrates the dynamic heat transfer effects on the roof caused by the intermittent shading of PV arrays, thereby facilitating a precise assessment of the overall energy
This positive cooling effect increases in poor insulated and high-reflectivity buildings (V. C. Kapsalis, Vardoulakis, & Karamanis, 2014). As Wang et al. mentioned, in the daytime, because of the shading effects of PV panels, the roof surface temperature is lower than the exposed roof.
Due to the cooling effect of green roofs, several studies had investigated the effect of green roofs in buildings with rooftop PV panels. The results of a study on a green roof integrated with a photovoltaic system show electricity generation improvement of PV panels (with 3%).
Increasing roof reflectance through the use of cool roofs or super cool roofs in urban installations of RPVSPs could significantly boost the energy production of solar panels. Cool photovoltaic technology promises a thermally optimized, modular and compact solar solution.
According to the results, PV panels mitigate the cooling load in all cases, but it is not the same for the heating load. By increasing the R -value, the effect of PV panels on cooling load decreases, while by decreasing solar absorption, the shading effect of PV panels decreases. Increasing solar absorption does not have a fixed effect.
