Solar panels are prone to accumulate dust after sandstorm weather, which affects the power generation efficiency. Timely cleaning is of vital importance. The following are the key points that need special attention during cleaning:
First, safety protection and preparation
Personal protection: Cleaning staff should wear dust masks, goggles, gloves, etc., to avoid inhaling sand and dust or getting scratched.
Tool inspection: Use soft cleaning tools such as soft brushes, sponges, and microfiber cloths. Avoid scratching the solar panels with hard tools.
Environmental assessment: Check whether the installation structure of the solar panels is stable and whether there are any potential safety hazards such as high-voltage lines around to ensure the safety of the clean environment.
Second, cleaning steps and techniques
Preliminary dust removal:
Use a soft-bristled brush or vacuum cleaner to gently remove large particles of sand and dust from the surface of the solar panels. Avoid directly rinsing with water to prevent the sand and dust from forming mud.
Moistening treatment
Moisten the surface of the solar panels with clean water or diluted eco-friendly cleaner to soften stubborn stains and facilitate subsequent cleaning.
Gently wipe:
Gently wipe along the grain direction of the solar panel with a sponge or microfiber cloth to remove stains and sand.
Stubborn stains can be wiped repeatedly, but avoid applying excessive force to prevent scratches.
Thorough rinse:
Thoroughly rinse the solar panels with clean water to remove any cleaner residues and stains, ensuring that no cleaner residues affect the power generation efficiency.
Drying treatment:
Dry with a clean microfiber cloth or let it air dry naturally to avoid water stains remaining.
Third, cleaning of special areas
Edges and gaps
Use a soft brush or cotton swab to clean the edges and crevices of the solar panels. These areas are prone to dust accumulation and are difficult to clean.
Connection part:
When cleaning, avoid touching or damaging the connection parts of the solar panels to prevent circuit failures or short circuits.
Fourth, inspection and maintenance after cleaning
Power generation efficiency monitoring
After cleaning, monitor the power generation efficiency of the solar panels to ensure the cleaning effect. If the power generation efficiency does not improve, check whether the solar panels are faulty.
Regular maintenance plan:
Formulate regular cleaning and maintenance plans based on sand and dust weather conditions to keep the solar panels clean and extend their service life.
Fifth, other precautions
Avoid cleaning during high-temperature periods:
Do not clean during high-temperature periods (such as noon) to prevent rapid evaporation of cleaning agents or moisture, which may affect the cleaning effect or damage the solar panels.
Water source and water quality:
Use clean water sources and avoid using water containing impurities or chemicals to prevent damage to the solar panels.
Record the cleaning situation:
Record the cleaning time, methods, tools and materials to facilitate subsequent reference and improvement of the cleaning process.
