Photovoltaic Modules
Cleaning is an issue that many people easily overlook. Most users do not realize the importance of regularly cleaning the modules to improve the system’s power generation efficiency, as well as some details that need to be paid attention to during the cleaning process. Today, we summarize issues related to the cleaning of photovoltaic modules.
The following are important considerations when cleaning photovoltaic modules:
1. To avoid personal exposure to sunlight, electric shock hazards, and potential damage to the modules due to wiping under high temperatures and intense sunlight, it is advisable for staff to clean the modules in the morning or later in the afternoon.
2. Before cleaning the modules, check the monitoring records for any abnormal power output, analyze if it may be caused by leakage, and inspect the connections and relevant components for any damage or sticking. It is also necessary to test the aluminum frame, brackets, and tempered glass surface of the modules with a voltage tester to eliminate potential electrical hazards and ensure personal safety.
3. Photovoltaic module aluminum frames and brackets have many sharp corners. Therefore, cleaning personnel should wear appropriate work clothes and hats to avoid injuries. It is prohibited to have hooks, straps, or loose threads on clothing or tools that might cause tripping hazards.
4. It is forbidden to step on photovoltaic modules, rail brackets, cable trays, or any other photovoltaic system equipment, or to use the module panels and brackets for support.
5. Cleaning photovoltaic modules is prohibited during adverse weather conditions, such as strong winds, heavy rain, thunderstorms, or heavy snow. In winter, avoid rinsing to prevent ice formation due to low temperatures, which can cause dirt accumulation. Similarly, do not rinse hot panels with cold water.
6. It is strictly forbidden to use hard, sharp tools or corrosive solvents and alkaline organic solvents to wipe photovoltaic modules. Do not spray cleaning water onto module junction boxes, cable trays, combiner boxes, or other equipment. The impact pressure of the cleaning equipment on the modules must be controlled within a certain range to avoid inducing micro-cracks due to improper stress.
7. During cleaning, personnel are prohibited from working within one meter of the roof edge. Tools and debris should not be thrown downwards, and all items must be taken away after the work is completed.
Users are advised not to clean the modules themselves if they are unfamiliar with the relevant professional cleaning knowledge. It is best to hire professional photovoltaic cleaning personnel to ensure that the modules are not damaged during the cleaning process.
