Have you ever had the experience of cleaning solar photovoltaic panel equipment? The issue of cleaning the photovoltaic panel modules can not be ignored. Many people do not have the correct understanding that not cleaning the modules regularly will directly affect the power generation of the system. I'm here to give you a heads up, cleaning solar photovoltaic panel equipment should not only pay attention to maintain the safety of the equipment, but also should pay attention to their own safety. Here we talk about what aspects worth our attention.
1, before cleaning, should truthfully record the power and other data to analyze whether it may be caused by leakage, and must check the component connection lines and related components for damage, adhesion, before cleaning also need to use the test pen to test the aluminum frame, bracket, tempered glass exterior of the component. To exclude the hidden danger of electricity leakage, to ensure personal safety.
2, strictly prohibited in the extreme climate of strong convection cleaning, high temperature, heavy rain, thunderstorms, heavy snow climate are as far as possible do not carry out cleaning operations, due to the high temperature climate is very likely to produce electric shock damage to the human body, thunderstorm climate is even more risky. Winter should also prevent the rinse method of cleaning, to prevent the low temperature of water gas into ice, dust and dirt accumulation, and ice simple fracture photovoltaic panels. Advocate the selection of morning and evening, sunlight weak time period cleaning, down the security risks
3, photovoltaic equipment components of the edge is sharp, the operator should wear the relevant work equipment before cleaning, maintenance of thorough, beware of scratching.

5、When cleaning, the operator needs to stand at a distance of less than 1 meter from the edge of the photovoltaic module operation. Prohibit stepping on photovoltaic modules, rail brackets, cable bridges and other photovoltaic system equipment or other ways to borrow the force of the component plate and bracket. If you use water pressure gun to flush, you should pay attention to the strength of the problem, to manipulate the impact pressure within a reasonable range, to prevent inappropriate force caused by the equipment plate hidden crack formation accident. Here advocate the use of automated intelligent equipment cleaning can improve safety.
6, to use the special cleaning solution. Some users use general tap water or well water to wash and clean the panel, because the water contains many impurities will be attached to the exterior of the battery components on the glass plate, reducing the solar power generation power. Some experiments have shown that the use of tap water to rinse the panel, than the use of special cleaning fluid cleaning will reduce the power generation power of more than 1.8%.
7, select the correct cleaning things and methods to improve the life of the panel. Solar panel battery exterior is a high-strength tempered glass, it also has the problem of wear and tear, solar panel life expectancy are more than 20 years, in order to ensure normal power generation, generally have to clean once or twice a month. If the use of methods and things are not appropriate, it is simple to form the battery exterior wear, affecting the power generation capacity and the life of the panel products.
8, to solve the problem of solar photovoltaic power plant cleaning in the winter and snow season. Winter snow season can not use water to clean the battery components, certain times of the year there is also the problem of condensation and ice on the panel, should be used with snow, dew, ice, waterless cleaning equipment.
