Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel surface cleaning technology, specifically a photovoltaic panel surface cleaning device. Background Technology

[0002] A photovoltaic (PV) panel is a portable power generation device. It is mainly composed of multiple solar cell units, which are usually made of semiconductor materials such as silicon. When sunlight shines on the PV panel, electrons in the semiconductor are excited, thereby generating an electric current. During operation, the surface of the existing PV panels is easily covered by dust, which requires workers to clean the PV panels after long-term use. Therefore, a PV panel surface cleaning device is needed.

[0003] Existing photovoltaic panel surface cleaning devices have certain drawbacks. These devices typically use a mobile cart to control the cleaning brushes to remove dust from the panel surface. However, photovoltaic panels are usually installed outdoors without any shade, resulting in a buildup of bird droppings. The high surface temperature of photovoltaic panels, combined with bird droppings containing highly viscous substances like uric acid and rich in organic matter such as protein and fat, causes the uric acid to harden into crystals that adhere tightly to the panel surface. The protein and fat-rich liquids, upon cooling, form sticky grime that is difficult to remove. The rotating cleaning brushes are ineffective at cleaning this sticky grime, failing to meet the required cleaning standards. Utility Model Content
