In winter, severe ice and snow weather often occurs in severe cold regions. In general, the low-temperature weather causes the ice and snow on the surface of the photovoltaic module to melt for a longer time, and the photovoltaic power generation efficiency is influenced. Moreover, the partially melted snow can also cause hot spot effect on the photovoltaic module, which affects the service life of the photovoltaic module and may even cause fire. Therefore, in severe cold areas where ice and snow easily occur, snow on the surface of the photovoltaic module needs to be removed manually to maintain the operation of the photovoltaic power station.
In the prior art, a specially-made snow removing device is adopted for cleaning and removing snow or an electric heating mode is adopted for heating and melting snow removal. For example, chinese patent CN204231282U discloses an automatic snow removing device for a roof photovoltaic power station, which first uses a heating film on a photovoltaic module to melt snow, so as to avoid the influence of icing on a snow brush, and uses a snow sweeping brush to sweep snow on the basis of melting snow on the heating film.

Test example
The power of the photovoltaic module is tested by adopting a 3500SLP module IV power tester (the photovoltaic module adopts the same materials except the coating), the water contact angle and the separation angle are tested by adopting a DR-1000 contact angle tester, and the surface temperature of the module is tested by adopting a Fluke62 infrared thermometer.
