How to use cleaning robot to clean different types of solar panel

Cleaning method adjustment: amorphous silicon photovoltaic panel is relatively fragile, in cleaning, the robot brush material should be softer. For example, a cleaner with a higher brush density but finer bristles can be used to avoid scratching the film on the surface of the photovoltaic panel during cleaning.
Cleaning power control: the cleaning power needs to be properly reduced. In the control system of the robot, the threshold of the pressure sensor should be lowered to reduce the spray pressure and brush friction on the panel. Generally, the spray pressure can be controlled between 0.2-0.3MPa, and the speed of the brush should also be appropriately reduced, such as controlled at 100-150 RPM.
Cleaning solution selection: If using a cleaning solution, choose a mild cleaning solution that is non-corrosive to amorphous silicon materials. The pH of the cleaning solution should be close to neutral, generally between 6-8, to prevent chemical damage to the thin film layer of the photovoltaic panel.

Monocrystalline silicon photovoltaic panel

Cleaning accuracy requirements: The surface of the monocrystalline silicon photovoltaic panel is smooth, and the cleaning accuracy is high. The robot's walking mechanism requires a more precise positioning system, such as a high-precision encoder, to ensure precise movement along the edges and gaps of the photovoltaic panel during cleaning, avoiding missing or repeated cleaning areas.
Stain treatment: For stubborn stains such as oil that may appear on the monocrystalline silicon photovoltaic panel, the robot may need to be equipped with a special degreaser nozzle. The composition of the oil remover should be selected according to the nature of the oil, such as for mineral oil pollution, you can use the oil remover containing surfactants and organic solvents, and ensure that it is thoroughly rinsed after cleaning to prevent residue.
Avoid damage measures: the monocrystalline silicon photovoltaic panel is relatively brittle, in order to avoid damage to the photovoltaic panel due to accidental collision during the working process of the robot, it is necessary to strengthen the collision detection system of the robot. For example, multiple infrared sensors are installed on the edge of the robot, which can adjust the walking route in time when it detects that the distance from the photovoltaic panel is too close.

Polycrystalline silicon photovoltaic panel

Cleaning frequency adjustment: The texture structure of the surface of the polycrystalline silicon photovoltaic panel is relatively complex, and it is easier to accumulate dust and other dirt, so the cleaning frequency may need to be higher than that of amorphous silicon and monocrystalline silicon photovoltaic panels. The robot's control system can optimize the setting of the cleaning cycle based on the data of the environmental dust detection sensor. For example, in dusty areas, the cleaning cycle can be shortened from the regular once a week to once every three days.
Brush structure optimization: Due to the surface structure characteristics of polysilicon photovoltaic panels, the robot's brush structure can be designed to have a certain elasticity and deformation ability. For example, using a brush with elastic bristles, the bristles can better fit the texture of the surface of the photovoltaic panel, and deeply remove dust in the gaps.
Drainage system strengthening: During the cleaning process, in order to prevent water from affecting the performance of the photovoltaic panel, the robot's drainage system should be more effective. Multiple drainage holes can be set up at the bottom of the robot, and the design of the drainage channel is optimized, so that the water after cleaning can be quickly discharged to avoid the formation of water stains on the photovoltaic panel.
