There are many cleaning tools for solar photovoltaic panels on the market. Our company’s solar cleaning brushes are customized and produced according to the specifications of different equipment. I would like to remind everyone to pay attention to the fact that the bristles are made of pure nylon material. The soft nylon filaments will not scratch the photovoltaic panel equipment and components and can be cleaned.
 
As a clean, environmentally friendly and pollution-free new energy source, solar energy has developed rapidly in recent years. Large-scale photovoltaic power stations have been built all over the world. Especially my country, as the largest photovoltaic country, has achieved world-renowned development achievements in photovoltaic power generation and increased installed capacity. It has ranked first in the world for five consecutive years. As of May 2018, my country's grid-connected photovoltaic installed capacity has exceeded 140 million, and the market has a huge market. From January to May 2018, my country's photovoltaic power generation capacity reached 66 billion kilowatt-hours. If calculated at the benchmark on-grid electricity price of photovoltaic power plants at 0.6 yuan per kilowatt-hour, my country's photovoltaic power generation price is about 40 billion.
 
It is worth noting that because photovoltaic power plants are built in open areas and sunny open-air environments, a large amount of dust, soot, fallen leaves, bird droppings and other dirt and dust marks remaining after the volatilization of rainwater will accumulate on the photovoltaic panels. All of these will seriously affect the absorption of solar light by photovoltaic panels and the conversion of electrical energy. The loss of photovoltaic power generation efficiency caused by different pollution accumulation ranges from 5% to 20%, and the resulting loss of electricity prices can reach as high as 2 billion to 8 billion yuan. In particular, obstructions such as stubborn gray stains, bird droppings and rainwater gray marks will form local shadows on the photovoltaic panel, which will increase the product of current and voltage of the local cells of the photovoltaic module, which will lead to local temperature rise and hot spots. The effect will reduce the actual service life of photovoltaic modules by at least 10%.
With the implementation of the 531 New Deal, photovoltaic power plants are bound to transition from the barbaric growth under the condition of state subsidies to the stage of focusing on refined operation and maintenance. The power generation efficiency of photovoltaic power plants must be maximized in order to recover the investment cost and create in the shortest time Maximum benefit. Regular and timely cleaning of photovoltaic modules is the most effective way to improve the power generation efficiency of photovoltaic power plants.
 
At present, there are two main ways to clean photovoltaic power plants: manual cleaning and robot cleaning. Manual cleaning has many shortcomings, such as long cleaning time, low efficiency, and high cost. In contrast, the use of photovoltaic cleaning robots for cleaning has many advantages such as high cleaning efficiency (3-5 times higher than manual cleaning efficiency), low cost (only 30%-50% of manual cleaning cost) and many other advantages. Robot cleaning also has two operation methods: waterless cleaning and water cleaning. At present, most of the domestic photovoltaic cleaning robot manufacturers are advertising that their robots can be cleaned without water, so they do not need to consume water, which is promoted as the biggest advantage. In fact, according to the experiments of the National Photovoltaic Laboratory, it is impossible to remove bird droppings, rainwater dust stains and other slightly stubborn stains on the surface of the board without using water and simply using a roller brush. These will inevitably cause The hot spot effect affects the service life of photovoltaic panels. In addition, for areas with large wind and sand, relatively large particles of sand will accumulate on photovoltaic panels.

Dry brushing without water can cause severe abrasion and scratches on the surface coating of photovoltaic panels, which will seriously affect the power generation efficiency of photovoltaic modules. The reason why the relevant manufacturers vigorously promote the waterless cleaning method is actually mainly because it cannot solve the problem of the robot slipping on the photovoltaic panel when there is water. The photovoltaic cleaning robot produced by Shanghai Weijiang Robot Technology Co., Ltd. adopts its special crawler with exclusive intellectual property rights, which can ensure that the crawler does not slip when the robot is working in water, and ensures the smooth and efficient progress of photovoltaic cleaning.
Photovoltaic cleaning robots are a new thing and have received great attention from the majority of photovoltaic power plant owners and photovoltaic enterprises in recent years. Photovoltaic cleaning robots must not only tell stories, but only promote various false gimmicks. They must be able to perform cleaning operations with water efficiently in order to truly improve the power generation efficiency and extend the service life of photovoltaic power plants, and they are truly practical photovoltaic cleaning robots.
