6 FAQs about [How to exhaust air from integrated solar energy]
How does solar module cooling work?
The solar module cooling technique can be applied in PV systems in structures that can use exhaust air from HVAC systems. Cooling is achieved through the forced convection of exhaust air on the rear sides of the panels, to absorb excess heat through heat transfer.
How does exhaust ventilation affect solar power output?
With lower solar radiation, exhaust ventilation decreases the electrical output, but it boosts the peak output by up to 1.69 W/m 2 when the solar radiation is high. The average PV temperatures for the EVPV-HP and NVPV systems are 11.86 and 9.71 ℃, respectively.
