Studies have shown that the method of adding cooling air and cooling water behind the photovoltaic panels can increase the power generation efficiency of the panels by 3-4%, but it also consumes a certain amount of energy consumption of fans or water pumps. In order to eliminate the waste heat in the working process of solar photovoltaic panels in time and use this part of waste heat (accounting for more than 83% of the total solar energy absorbed), it is very necessary to study the waste heat that can effectively take away the working process of photovoltaic panels without reducing the waste heat. Solar photovoltaic thermal integration technology with high power consumption is required to achieve efficient utilization of solar energy.
