Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment maintenance, and more specifically, to an active snow melting device for photovoltaic panels. Background Art

[0002] In winter, photovoltaic power generation is easily reduced due to snowy weather. Continuous snowfall will completely cover the photovoltaic panels, and the surface of the photovoltaic panels cannot be exposed to sunlight. The thick snow reflects all the sunlight back. Usually, manual snow removal is used to clear the snow on the photovoltaic panels, but if you are facing a photovoltaic power station of tens or hundreds of megawatts, the workload of manual snow removal is undoubtedly huge.
