The daily maintenance and cleaning of solar panels
Key Points of Daily Maintenance
1. Regularly inspect the appearance condition
Inspection frequency: At least once a month (frequency should be increased in areas with strong sandstorms and heavy rainfall).
Inspection contents:
Surface cleanliness: Observe whether there are any obstructions such as dust, bird droppings, leaves, and snow. If the obstructions exceed 10%, it may lead to a significant decrease in efficiency.
Physical damage:
Inspect the glass for cracks, breaks, or bubbles that were created by either hail, high winds from storms, or due to improper installation of the glass.
Make sure to check the frame for any deformation and corrosion (watch for oxidation on aluminum alloy frames) also ensure the screws are not loose.
Ensure that any junction boxes and wiring are not damaged or exhibit any signs of aging and that any junctions are not loose as a loose joint can allow short circuits or poor contact.
In addition, check for any buildup of foreign objects. This includes looking for weeds or fallen leaves accumulating at the base of the building or in the gaps between planks. Any buildup can lead to dampness or pest problems.
2. Monitor the power generation efficiency
Comparison of the power produced by the inverter over the past month will be made against how much power the inverter should have produced in the same timeframe. If there is still a major difference (>10% reduction compared to the averages from past weeks) this could be due to a lack of proper cleaning or failure of one or more components.
Key investigation:
If panel appears to be producing abnormally low readings, this could be because there are trees/local obstructions blocking the sunlight, or due to damage to the solar cell or other reasons.
If the entire system is still under-performing check to see if the boards are clean; then check the inverter, wiring, and any other devices connected to the inverter.
3. Deal with special weather conditions
Typhoons or Heavy Rains: After experiencing either typhoons or heavy rains, ensure the structure is intact; the solar panel should be intact as well; excess water & debris have been removed from the top of the solar panel.a
Heavy Snow Accumulation: As soon as possible remove snow accumulation (to prevent water from melting/ refreezing). Use either a soft bushing device to move the accumulated snow from the bottom up or a broom in reverse motion.
Minimal ventilation in hot weather: Ensure heat can escape freely during hot weather by ensuring there is adequate ventilation (10cm min. recommended distance between solar panel body & the installation surface). Increasing temperatures cause lower operational efficiency.
Cleaning ratio Guide-Daily Maintenance And Cleaning Of Solar Panels
1. Cleaning frequencyGeneral areas: Clean once every 3 to 6 months (adjusted according to air quality and the rate of dust accumulation).
Highly polluted areas: Such as industrial zones, desert edges, and coastal (salt spray) areas. It is recommended to do this once a month.
Hint: Frequent cleaning may increase the risk of wear and tear. It is necessary to balance the benefits of cleaning and maintenance costs.
2. Clean tools and materials
| tools/materials | Purpose | Precautions |
| a soft broom or mop | Remove loose debris such as dust and leaves | Choose nylon or sponge materials to avoid the metal brush head scratching the glass surface |
| The low-pressure water gun | Rinse off stubborn stains (such as bird droppings and grease) | The water pressure should be ≤0.2MPa (approximately 2 kilograms of pressure) to prevent high-pressure water flow from impacting the seams of the frame or the back plate, which may cause water ingress and damage |
| Neutral detergent | Remove sticky stains (such as fruit juice, shellac) | Use neutral detergent with a pH value of 6 to 8. Do not use alcohol or acidic/alkaline cleaners (which may corrode the sealant). |
| microfiber cleaning cloth | Wipe off any remaining water stains or stubborn dirt | Soft material, avoiding the wear of the anti-reflective layer caused by repeated friction |
| ladders or safety equipment | Used when working at heights | Make sure the ladder is stable, wear a safety belt and avoid single-person operation |
