The invention discloses a photovoltaic module cooling, cleaning and efficiency-improving
system. The photovoltaic module cooling, cleaning and efficiency-improving
system comprises a photovoltaic module, a photovoltaic support, a water spraying device, a cleaning device, a water spraying
pipe, a cleaning hose, a temperature sensor, a
water flow meter, a water spraying
electromagnetic valve, a cleaning
electromagnetic valve, a PLC and a high-pressure water pump communicating with a
water source, wherein the photovoltaic module is installed on a roof through the photovoltaic support, the water spraying device is installed at the high position of the roof, the cleaning device comprises a moving mechanism and a brushing mechanism, the brushing mechanism is installed above the photovoltaic module through the moving mechanism, and the brushing mechanism makes brushing contact with the top face of the photovoltaic module. According to the photovoltaic module cooling, cleaning and efficiency-improving
system, the surface temperature of the photovoltaic module can be reduced, and dust and
dirt on the surface of the photovoltaic module can also be cleaned in time, so that the power generation efficiency and the power generation capacity of the photovoltaic module are improved, the use performance of the photovoltaic module is ensured, and the service life of the photovoltaic module is prolonged.
