Photovoltaic module cleaning 7 major considerations
About component cleaning is a problem that many people easily overlook. Most people are not aware of the importance of regular cleaning components for improving the system's power generation efficiency, and some details that need attention when cleaning components. Today, the issues related to the cleaning of photovoltaic modules are summarized. The following are the points to note when cleaning PV modules: 1. In order to avoid the risk of electric shock to the human body by wiping the module under high temperature and strong light, and possible damage to the components, the workers generally choose to perform component cleaning in the morning or in the late afternoon. 2. Before performing component cleaning, check whether there is an abnormal power output record in the monitoring record. Analyze whether it can be caused by leakage, and check whether the connection lines and related components of the component are damaged or blocked. Before cleaning, you need to use The test pencil tests the aluminum frame, bracket, and tempered glass surface of the assembly. To eliminate potential leakage hazards and ensure personal safety. 3. Photovoltaic modules Aluminium frames and photovoltaic supports have many sharp corners. Therefore, personnel performing component cleaning should wear appropriate work clothes and wear hats to avoid scratching. Hooks and straps should be prohibited on clothing or tools. Lines and other parts that are likely to cause drag. 4. It is forbidden to step on photovoltaic system equipment such as photovoltaic modules, rail brackets, cable trays, etc., or leveraging other methods to leverage component boards and brackets. 5. Never clean photovoltaic modules under meteorological conditions with strong winds, heavy rain, thunderstorms, or heavy snow. Cleaning in winter should avoid flushing to prevent freezing and accumulation of dirt due to low temperatures. Similarly, do not rinse with cold water when the panel is very hot. 6. It is forbidden to use hard and sharp tools or corrosive solvents and alkaline organic solvents to wipe the PV modules. It is forbidden to spray cleaning water to the equipment junction boxes, cable trays, and combine boxes. The impact pressure of the cleaning device on the components during cleaning must be controlled within a certain range to avoid cracking caused by stress. 7. When the person is clean, it is forbidden to stand at a place less than 1 meter away from the edge of the roof. Do not throw tools and debris down and take them with you after the assignment. Finally, users are not advised to clean themselves without knowing the relevant professional cleaning knowledge. It is best to have professional PV cleaning personnel perform cleaning and overhaul to better ensure that the PV modules are not damaged during the cleaning process.
