When cleaning solar panels, the use of cleaning agents should be carefully selected and operated to ensure the cleaning effect while avoiding damage to the panels. The following are the key points to note when using cleaning agents:
First, the selection of cleaning agents
Environmentally friendly and non-corrosive
The cleaning agent should be environmentally friendly and free of harmful chemicals to avoid pollution to the environment.
The cleaning agent should be non-corrosive and not erode the glass, coating or sealant on the surface of the solar panel to prevent a reduction in the service life and power generation efficiency of the solar panel.
Strong decontamination ability
Choose a cleaner with strong decontamination ability, which can effectively remove stubborn stains such as bird droppings, resin and oil stains on the surface of the solar panels.
The cleaning agent should be easy to dissolve stains and convenient for subsequent rinsing clean.
Good compatibility
The cleaning agent should be compatible with the material of the solar panel to avoid surface discoloration, peeling or performance degradation caused by chemical reactions.
For solar panels with special coatings, it is necessary to confirm whether the cleaner is suitable for that coating.
Second, the usage method of the cleaning agent
Dilution ratio:
According to the instructions on the cleaner, dilute it in the correct proportion to avoid excessive concentration that may cause residue or corrosion.
When diluting, clean water should be used to prevent impurities in the water from affecting the cleaning effect.
Local test
Before large-scale use, conduct a local test on an inconspicuous position of the solar panel first. Only after confirming that the cleaner has no adverse reactions can it be used comprehensively.
Spray or apply evenly:
Spray or apply the diluted cleaner evenly on the surface of the solar panel to ensure that all stained areas are covered.
Avoid direct contact of the cleaner with the electrical connection parts of the solar panel to prevent short circuits or damage.
Gently wipe:
Gently wipe the surface of the solar panel with a soft sponge, soft-bristled brush or microfiber cloth to ensure that the cleaner fully reacts with the stains.
When wiping, follow the texture direction of the solar panel to avoid scratching the surface.
Third, post-cleaning treatment
Thorough rinse:
Thoroughly rinse the surface of the solar panels with clean water to remove any residue of the cleaner and stains.
When rinsing, ensure that the water flow is uniform to avoid local water accumulation or omission.
Dry the surface:
Use a clean microfiber cloth or let it air dry naturally to remove the moisture on the surface of the solar panel.
When drying, operate gently to avoid leaving water stains or fiber residues.
Check the cleaning effect:
After cleaning, it is necessary to check whether the surface of the solar panels is clean and free of stains, and whether the power generation efficiency has been improved.
If poor cleaning effect or abnormality of the solar panels is found, the cause should be identified and dealt with in a timely manner.
Fourth, other precautions
Avoid mixed use:
Different brands or types of cleaning agents may contain different chemical components. Mixing them may cause harmful reactions or reduce the cleaning effect.
Therefore, when using cleaning agents, it is necessary to avoid mixing them and strictly follow the product instructions for operation.
Storage and custody
Cleaning agents should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight or high-temperature environments that may cause deterioration.
After use, it should be sealed and stored in time to prevent evaporation or contamination.
Personnel Training and Safety
Cleaning staff need to receive professional training to understand the usage methods and precautions of cleaning agents.
When using cleaning agents, protective equipment (such as gloves, goggles, etc.) should be worn to ensure operational safety.
