After sand and dust weather, a large amount of sand and dust will accumulate on the surface of solar panels, seriously affecting their power generation efficiency. Therefore, it is crucial to clean the solar panels in a timely and effective manner. The following are the key points to note for cleaning solar panels after sandstorm weather:
First, preparations before cleaning
Safety assessment
Before cleaning, it is necessary to assess the safety of the cleaning environment, including checking the stability of the installation structure of the solar panels and whether there are any potential safety hazards such as high-voltage lines and sharp objects around.
For solar panels installed at heights, safety belts, anti-slip shoes and other protective equipment should be used to ensure the safety of the cleaning staff.
Tool and material preparation:
Prepare soft sponges, soft brushes, microfiber cloths and other cleaning tools. Avoid using hard tools that may scratch the solar panels.
Prepare an appropriate amount of clean water or a special cleaner as needed (make sure the cleaner is non-corrosive and environmentally friendly).
Prepare auxiliary equipment such as buckets and water guns (if applicable).
Second, key points to note during the cleaning process
Preliminary dust removal:
Use a soft brush or vacuum cleaner to gently remove large particles of sand and debris from the surface of the solar panels. Avoid directly rinsing with water, which may cause sand and dust to form mud on the surface of the solar panels and increase the difficulty of cleaning.
Moist and clean
Moisten the surface of the solar panel with clean water or diluted cleaner to soften stubborn stains.
Pay attention to controlling the amount of water to avoid excessive moisture seeping into the interior of the solar panels and causing damage.
Gently wipe:
Use a sponge, soft brush or microfiber cloth to gently wipe the surface of the solar panel, starting from one end and gradually cleaning along the grain direction to the other end.
For stubborn stains, you can appropriately increase the wiping force or repeat the cleaning steps, but be careful not to apply excessive force to avoid scratches.
Rinsing and drying
Thoroughly rinse the surface of the solar panels with clean water to remove any residue of the cleaner and stains.
Use a clean microfiber cloth or let it air dry naturally to remove surface moisture to avoid water stains remaining and affecting power generation efficiency.
Third, handling of special circumstances
Stubborn stain treatment:
For stubborn stains such as bird droppings and resin, special cleaners or mild solvents can be used for local treatment, but it is necessary to ensure that the solar panels will not be damaged.
After processing is completed, it needs to be thoroughly rinsed with clean water and dried.
Edge and crevice cleaning
Special attention should be paid to cleaning the edges and crevices of the solar panels, as these areas are prone to accumulate sand, dust and stains and are difficult to clean.
A slender soft-bristled brush or cotton swab can be used for meticulous cleaning.
Fourth, inspection and maintenance after cleaning
Check the power generation efficiency:
After the cleaning is completed, the power generation efficiency of the solar panels needs to be monitored to ensure that the cleaning effect meets expectations.
If it is found that the power generation efficiency has not been significantly improved, it is necessary to check whether the solar panels have other faults or damages.
Regular maintenance
Establish a regular cleaning and maintenance plan and determine the cleaning frequency based on the local sand and dust weather conditions.
Regularly inspect the installation structure and connection lines of the solar panels to ensure their safe and stable operation.
Fifth, other precautions
Avoid cleaning during high-temperature periods:
Do not clean during high-temperature periods (such as noon) to avoid rapid evaporation of cleaning agents or moisture, which may lead to poor cleaning results or damage to the solar panels.
Record the cleaning situation:
Record the time, method, tools and materials used for each cleaning, etc., for subsequent reference and improvement.
