Abstract

In the work, sky radiative cooling module is set between two adjacent rows of photovoltaic modules in the north-south direction, which can not only effectively use the roof area, but also improve the cooling performance. The cooling capacity generated by the cooling module is transferred to the heat exchange module on the back of photovoltaic modules through the water system, thus cooling the photovoltaic panels and improving the operation effect of the PV system. The experimental results show that the system can reduce the average daily temperature of photovoltaic panels by 13.6 ℃ and 10.6 ℃ in summer and autumn, and enhance power generation efficiency by 1.21% and 0.96% respectively.
