Problems solved by technology

With the occurrence of different degrees of smog in various regions of our country, the particles on the surface of solar photovoltaic cell modules are not easy to clean up, resulting in a decrease in the solar radiation received by the panels, resulting in a reduction in the power generation of the photovoltaic conversion system
In addition, after the attachment absorbs solar radiation, the photovoltaic panel heats up, and the attachment contains corrosive chemical components, which will lead to a decrease in photoelectric conversion efficiency
At present, the cleaning of photovoltaic panels on the market is mainly through manual cleaning. Manual cleaning cannot carefully clean each photovoltaic panel. At the same time, due to limited manpower, it is often impossible to clean photovoltaic panels in time. Not only is the cleaning efficiency low, but also Affect the power generation efficiency of photovoltaic panels; some photovoltaic panels are installed in dangerous places such as roofs, manual cleaning has certain safety hazards, and it will also increase the difficulty of cleaning
In addition, because manual cleaning can only be done during the day, and the daytime is when the light is strongest, photovoltaic panels can basically only generate power during the day, so cleaning during the day will also affect the power generation efficiency of photovoltaic panels
Therefore, the existing technology has the problems of low cleaning efficiency, high cleaning difficulty, unsatisfactory cleaning effect, potential safety hazards, and problems that will affect the power generation efficiency of photovoltaic panels.

Abstract

The invention discloses an automatic solar photovoltaic surface cleaning device and a cleaning method thereof. The automatic solar photovoltaic surface cleaning device comprises a supporting frame (2); an attachment monitoring unit (3) is arranged at the upper end of the supporting frame (2); cleaning units (4) are arranged on the two sides of the supporting frame (2); a supplemental lighting unit (5) is arranged at the lower end of the supporting frame (2); the attachment monitoring unit (3) comprises a scanner (31); the scanner (31) is connected with a computer processing unit (6); the computer processing unit (6) is connected with a controller (7) and a photosensitive sensor (32); and the controller (7) is connected with the supplemental lighting unit (5) and the cleaning units (4). The cleaning method is characterized in that the surface of a photovoltaic panel is scanned by using the scanner, the quantity n of attachments in a unit area is calculated through the computer processing unit, and the cleaning units are controlled to work through the controller. The automatic solar photovoltaic surface cleaning device has the characteristics that the cleaning efficiency can be improved, the cleaning of the photovoltaic panel is facilitated, the cleaning effect is improved, potential safety hazards are eliminated, and the influence on power generation of the photovoltaic panel can be reduced.

Description

technical field [0001] The invention relates to a photovoltaic panel cleaning device, in particular to an automatic solar photovoltaic surface cleaning device and a cleaning method. Background technique [0002] In recent years, solar photovoltaic cells have been widely used, and the output of photovoltaic power generation systems is affected by many factors. With the occurrence of different degrees of smog in various regions of our country, the particles on the surface of solar photovoltaic cell modules are not easy to clean up, resulting in a decrease in the solar radiation received by the panels, resulting in a reduction in the power generation of the photovoltaic conversion system. In addition, after the attachment absorbs solar radiation, the photovoltaic panel heats up, and the attachment contains corrosive chemical components, which will lead to a decrease in photoelectric conversion efficiency. At present, the cleaning of photovoltaic panels on the market is mainly ...
