【Solar panel brushGPAA】: Usage scenario: It is inconvenient to drag the cable, so it is not suitable for mobile cleaning or large-area power stations. The solar panel cleaning brush is equipped with a 220V to 24V DC power supply and a power cord of more than ten meters..Telescopic rod diameter: 40mm. Alloy telescopic rod length specifications are 3.5m, 5.5m, 7.5m 【Solar panel brushGPBB】: Usage scenario: Equipped with a lithium battery and a backpack, it can be carried on the body for mobile cleaning, fast and efficient. The solar panel cleaning device is equipped with a set of lithium batteries and a backpack,and the battery life is 4-8 hours. Telescopic rod diameter: 40mm.Telescopic rod diameter: 40mm. Alloy telescopic rod length specifications are 3.5m, 5.5m, 7.5m 【Adjustable Length】: The locking buckle structure is adoptedand the length of the telescopic rod can be adjusted at will, can reach 2-12 meters long distance cleaning photovoltaic power station. Imported nylon thread, high density, hand-woven into a plate, the fiber will not fall off and damage the photovoltaic panel. 【High cleaning efficiency】: The electric double-head photovoltaic panel cleaning equipment has a cleaning width of 70cm, and each person can clean 500-750 square meters per hour and can wash 3,500-5,000 meters squares with 8 hours of work. The water consumption is about 1.5-3L/m³ and the cleaning water consumption is about 9-15 tons/MW, which saves a lot of water. 【USES】: The opposite rotation of the double brush head is balanced, and the electric brush rotates at high speed. The friction force of the water jet at the same time strongly removes dust and sticky dirt on the photovoltaic panel. Suitable for commercial large-area cleaning environments without electricity, such as distributed factory roofs, large power plants and solar power plants in the mountains.
