Factors Influencing Cleaning Frequency:
Consider factors like dust, dirt, bird droppings, and weather conditions to determine how often your panels should be cleaned.
Climate Factors:
In areas where dust is common, such as deserts or coastal regions, your solar panels are more likely to collect dirt quickly and will need cleaning on a more regular basis.
Seasonal Changes:
During spring, pollen can build up on the panels, and winter snow can block sunlight, reducing efficiency. You may need to clean your panels more often in these seasons.
Panel Tilt:
If your solar panels are angled over 15°, rain can help wash away dirt naturally, making regular cleaning less necessary.
Panel Placement:
Solar panels located near factories, busy roads, or construction sites may gather dirt at a faster rate, so they might need cleaning more frequently.
