7 major considerations for PV module cleaning
[China Glass Network] About component cleaning is a problem that many people tend to ignore. Most people are unaware of the importance of regular cleaning components to improve system power generation efficiency, as well as some details to be aware of when cleaning components. Today, the issues related to the cleaning of photovoltaic modules are summarized. The following are the things to be aware of when cleaning PV modules: Cashmere Scarf,Cashmere Wrap,Cashmere Snood,Pure Cashmere Scarf Inner Mongolia Jinshitaihua Cashmere Accessories Co.,Ltd , https://www.nmgshineland.com
1. In order to avoid the electric shock damage to the human body and the damage to the components under high temperature and strong light, the staff generally choose to clean the components in the morning or late in the afternoon.
2. Before cleaning the components, check whether there is any abnormality in the output of the monitoring records. Analyze whether it is possible to cause leakage due to leakage, and check the connection wires and related components of the components for damage and adhesion. The test pencil tests the aluminum frame, bracket, and tempered glass surface of the assembly. In order to eliminate potential leakage, to ensure personal safety.
3. PV module aluminum frame and photovoltaic bracket have many sharp corners. Therefore, personnel who perform component cleaning should wear appropriate overalls and wear a hat to avoid injury and injury. Hooks and straps on clothing or tools should be prohibited. A part that is easily caused by a thread.
4. It is forbidden to step on PV modules such as PV modules, rail brackets, cable trays or other means to leverage component boards and brackets.
5. It is strictly forbidden to clean the PV modules under meteorological conditions such as heavy wind, heavy rain, thunderstorm or heavy snow. Winter cleaning should be avoided to prevent the temperature from falling too low and freezing, causing dirt to accumulate; for the same reason, do not rinse with cold water when the panel is very hot.
6. It is forbidden to wipe the PV module with hard and sharp tools or corrosive solvents and alkaline organic solvents. It is forbidden to spray the cleaning water to the component junction box, cable tray, combiner box and other equipment. The impact pressure of the cleaning equipment on the components during cleaning must be controlled within a certain range to avoid cracking that is not caused by force.
7. When cleaning personnel, it is forbidden to stand at a position less than 1 meter from the edge of the roof. Do not throw tools and debris down and take them away after the job is completed.
Later, it is not recommended to clean the user himself without knowing the relevant professional cleaning knowledge. It is better to have professional PV cleaning personnel to carry out cleaning and maintenance, in order to better ensure that the PV modules are not damaged during the cleaning process.
