When cleaning components, we should also pay attention to 7 points
1. In order to avoid electric shock damage and possible damage to the components caused by wiping the components under high temperature and strong light, the staff generally chooses to clean the components in the morning or late afternoon.
2. Before cleaning the components, check whether there is any abnormal power output record in the monitoring records, analyze whether it may be caused by leakage, and check whether the connecting wires and related components of the components are damaged or stuck. Before cleaning, it is necessary to use The test pen tests the aluminum frame, bracket, and tempered glass surface of the component. In order to eliminate hidden dangers of leakage and ensure personal safety.
3. The aluminum frame of the photovoltaic module and the photovoltaic support have many sharp corners. Therefore, the personnel cleaning the components should wear corresponding work clothes and hats to avoid scratching and injury. Hooks and straps on clothing or tools should be prohibited. Threads and other parts that are easy to cause entanglement.
4. It is forbidden to step on photovoltaic modules, guide rail brackets, cable trays and other photovoltaic system equipment or rely on component boards and brackets in other ways.
5. It is strictly forbidden to clean photovoltaic modules under the meteorological conditions of strong wind, heavy rain, thunderstorm or heavy snow. Winter cleaning should avoid rinsing to prevent the temperature from freezing and causing dirt accumulation; similarly, do not rinse with cold water when the panel is hot.
6. It is strictly forbidden to use hard and sharp tools or corrosive solvents and alkaline organic solvents to wipe photovoltaic modules, and it is forbidden to spray cleaning water to the module junction box, cable tray, combiner box and other equipment. When cleaning, the impact pressure of the cleaning equipment on the components must be controlled within a certain range to avoid cracks that are not caused by force.
7. When cleaning personnel, it is forbidden to stand less than 1 meter away from the edge of the roof. Do not throw tools and sundries down, and take them away after the work is completed.
