Background technique

Photovoltaic is a new energy sector. Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has independent operation and grid-connected operation. Two ways. Because photovoltaic panels are exposed to the air for a long time, they are sometimes covered with dust, bird droppings, leaves and other dust substances, thereby reducing the power generation efficiency of the photovoltaic panels. Therefore, photovoltaic panels need to be cleaned regularly to increase their production capacity.

The conventional cleaning method is to rinse the photovoltaic panels directly with tap water. Before use, first gently brush off the larger dust and substances accumulated on the photovoltaic panels to avoid scratching the surface of the photovoltaic panels. Next, aim the water pipe or water gun at the surface of the photovoltaic panel, use higher water pressure to rinse away dust, bird droppings, leaves and other substances, and finally wipe it clean with a brush or roller. However, this conventional cleaning method has the following shortcomings:

First of all, although this cleaning method has low cleaning costs, when it comes to large-area photovoltaic panels, the cleaning workload is heavy, which not only requires a large increase in labor costs, but also some photovoltaic panels are installed at a high height, which makes cleaning difficult.
