Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to photovoltaic dust removal equipment. Background Art

[0002] Solar energy refers to the thermal radiation energy of the sun. Solar energy has become an important part of human energy and is constantly developing. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are composed of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices. Most of the existing photovoltaic power generation equipment will produce a lot of dust covering the surface of the equipment due to long-term exposure to the outdoors, which is difficult to clean. The accumulation of dust significantly reduces the luminous flux of photovoltaic modules, and thus significantly reduces the power output capacity of photovoltaic modules.

[0003] 1. In the existing technology, the traditional front-end manual cleaning is for cost control considerations. Most of the cleaning staff are older, and it is common to be in their 50s and 60s. There are great problems in their management. In addition, the probability of danger is high when the elderly cleaning staff are cleaning, especially when cleaning rooftop photovoltaic power stations, which will cause great safety hazards to the power station owners.

[0004] 2. In the prior art, the traditional cleaning and dust removal methods have a large momentum, resulting in poor cleaning effects: they mainly use long-pole brushes and other methods, which are difficult to operate and cannot guarantee consistent effects before and after the same cleaning cycle. The quality of cleaning is acceptable in the early stage, but as time goes by, due to the large amount of manual cleaning labor, the cleaning quality will seriously decline due to fatigue in the middle and late stages of cleaning, and the overall cleaning effect will be greatly reduced.
