Among them, the arc-ribbed cavity structure PV wall panels have the best heat dissipation effect. Further studies have shown that the curvature, rib height, width, and spacing of the curved ribs significantly affect the heat dissipation performance of the photovoltaic panels.
The study sets the environmental temperature at 25°C and analyzes the temperature of the two types of photovoltaic panels under solar radiation strengths of 400 W/m 2, 600 W/m 2, 800 W/m 2, and 1000 W/m 2. Figure 23. Schematic diagram of cavity structure of ventilated photovoltaic wall panels.
Further studies have shown that the curvature, rib height, width, and spacing of the curved ribs significantly affect the heat dissipation performance of the photovoltaic panels. Compared to the flat-plate cavity structure, the parameter-optimized curved-rib cavity structure significantly reduces the average surface temperature of PV panels.
In addition, while water-cooled photovoltaic panels can improve heat dissipation, they are expensive to maintain and risk leakage. Mechanical ventilation, though more effective, poses challenges for practical implementation in engineering applications. In real projects, air-cooled channels have been integrated into PV systems.
