In order to ensure the system efficiency of the photovoltaic power station, improve the generated energy of the power station, timely remove accumulated dust and stains, properly control the temperature of the photovoltaic module and have important significance on the efficient and safe operation of the power station.

In addition, in any type of photovoltaic module, in summer or tropical regions, especially in installation positions with poor heat dissipation conditions such as flat roofs of industrial and commercial roofs, the photovoltaic module heats up after absorbing heat, and the power generation efficiency is reduced due to an excessively high temperature. At present, a distributed photovoltaic power generation system installed on a roof generally has no special temperature control system, a photovoltaic module mainly depends on radiation and air convection for heat dissipation, and at installation positions with poor heat dissipation conditions such as plane roofs of industrial and commercial roofs, the temperature of the photovoltaic module is excessively increased after heat absorption, and the power generation efficiency is reduced due to the excessively high temperature (when the temperature of the module is increased to 70 ℃ from 20 ℃, the peak power is lost by 20%).
