Seven Points for Attention in Cleaning Distributed Photovolt

2019-06-19

Most people are unaware of the importance of cleaning components regularly to improve the efficiency of power generation, as well as some details that need to be paid attention to when cleaning photovoltaic panels. Today, the problems related to distributed photovoltaic panel cleaning are summarized.
1. Generally choose to do component cleaning in the morning or later in the afternoon.
2. Before cleaning photovoltaic panel, it is necessary to inspect whether there is any abnormal record of power output in the monitoring record, analyze whether it is likely to be caused by leakage of electricity, and check whether the connecting wires and related components of the components are damaged or adhered. Before cleaning, it is necessary to test the aluminum frame, bracket and tempered glass surface of the components with a test pen, in order to avoid potential leakage hazards and ensure personal safety.
3. Aluminum frame and support of photovoltaic module have many sharp corners. Operators should wear the corresponding work clothes and hats to avoid scratching injury. Hooks and belts on clothes or tools should be prohibited.
4. It is forbidden to tread on photovoltaic module, guide rail bracket, cable bridge bracket or other board.
5. It is strictly forbidden to clean photovoltaic modules under the weather conditions of gale, heavy rain, thunderstorm or heavy snow. Avoid washing in winter to prevent freezing. Similarly, cold water should not be used to wash when photovoltaic panel is very hot.
6. It is strictly forbidden to wipe photovoltaic modules with hard and sharp tools or corrosive solvents and alkaline organic solvents. It is forbidden to spray cleaning water into assembly junction boxes, cable bridges, confluence boxes and other equipment. When cleaning, the impact pressure of cleaning equipment on components must be controlled within a certain range to avoid cracking caused by force.
7. When cleaning, it is forbidden to stand less than 1 meter from the edge of the roof. No tools and sundries are allowed to be thrown downward and all tools and sundries should be taken away after the operation is completed.
