Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module cleaning mechanisms, and more specifically, to a self-propelled photovoltaic module cleaning mechanism. Background Technology

[0002] A solar panel is a device that absorbs sunlight on its surface and converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Since solar panels are placed outdoors, after a period of use, the surface of the solar panel will be blocked by dust, debris, etc. After the surface is blocked, the efficiency of the solar panel in receiving sunlight will be greatly reduced. According to statistics, if the surface of the solar panel is not cleaned for a long time, its light conversion efficiency will decrease by more than 30%, which will seriously affect the power generation efficiency.

[0003] To reduce sunlight shading, solar panels typically require periodic cleaning. Traditionally, this is done manually, using specialized cleaning tools to clean the surface of the solar panels. However, manual cleaning is not only labor-intensive but also time-consuming, hindering efficiency. Therefore, we propose a self-propelled photovoltaic module cleaning mechanism.
