1. Before cleaning, you should truthfully record the power and other data to analyze whether it can be caused by leakage, and check whether the connecting wires and related components of the module are damaged or stuck. Before cleaning, you need to use a test pencil to test the aluminum frame and bracket of the module. , Test the surface of toughened glass. In order to eliminate the hidden danger of leakage and ensure personal safety.
2. It is strictly forbidden to clean under extreme weather with strong convection. Do not clean as much as possible in the weather of high temperature, heavy rain, thunderstorm and heavy snow, because the high temperature weather is very likely to cause electric shock to the human body, and thunderstorm weather is even more dangerous. It is also necessary to avoid washing in winter to prevent the low temperature and moisture from forming ice, dirt accumulation, and ice fracturing the photovoltaic panel. It is recommended to clean in the morning and evening, when the sun is weak, to reduce potential safety hazards
3. The edges of the components of the solar photovoltaic panel equipment are sharp, and the staff should wear relevant work equipment before cleaning, take full protection, and beware of scratches.
4. When cleaning, the staff should stand at a place less than 1 meter away from the edge of the photovoltaic module. It is forbidden to step on photovoltaic modules, rail supports, cable trays and other photovoltaic system equipment or use other means to rely on module boards and supports. When flushing with a water pressure gun, attention should be paid to the problem. The impact pressure should be controlled within a reasonable range to avoid accidents caused by improper force causing the equipment board to crack. It is recommended to use automated smart device cleaning to improve safety.
