Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel cleaning technology, and in particular relates to a surface cleaning device for solar photovoltaic panels. Background Technology

[0002] A solar photovoltaic (PV) panel is a device that uses the photovoltaic effect of semiconductor materials (such as silicon) to directly convert sunlight into electrical energy. It typically consists of multiple photovoltaic cells connected in series or parallel, encapsulated in protective materials such as glass and a backsheet to form a robust and durable panel. PV panels generate direct current (DC) under sunlight, which can be converted into alternating current (AC) by an inverter for use in homes, businesses, or industries. It is a core component of clean, renewable, and pollution-free green energy technology, widely used in rooftop power generation, photovoltaic power plants, and various off-grid power supply systems. After production, solar PV panels may have some stains and dust on their surface, requiring cleaning.

[0003] Existing solar photovoltaic panel surface cleaning devices mostly employ fixed brush roller structures in practical use, which cannot flexibly adjust the cleaning position according to the size deviation or installation tilt angle of the photovoltaic panel, easily resulting in cleaning dead areas. Some devices only have a single water rinsing function and lack a pretreatment step to soften stains with cleaning fluid, leading to incomplete removal of stubborn stains and making them inconvenient for workers. In view of this, we propose a solar photovoltaic panel surface cleaning device. Utility Model Content
