Technical FAQs 4

Do solar panels need to be cleaned?

So, for most people, cleaning home solar panels isn’t necessary. Research indicates that solar panels in moderate climates experience just a 3% annual loss from soiling. However, if you live in a particularly dusty environment, like the Middle East, North Africa, or India, your solar panels could see their output reduced by 40% or more over a year.

Why do I need to clean my solar panels?

Seasonal Changes: Pollen in spring or snow in winter may necessitate timely cleanings. Panel Tilt: Panels tilted at 15° or more benefit from natural rainwater cleaning, reducing maintenance needs. Pollution Sources: Proximity to highways or factories increases dirt accumulation. Incorrect methods can damage panels or void warranties.

When should I clean my solar panel?

Early spring and late fall are ideal. This solar panel maintenance guide recommends cleaning when panels are cool—like early morning or overcast days—to avoid thermal shock and get the most effective results. FAQ 3: Can I use a pressure washer as part of my solar panel maintenance guide?

Should you turn off solar panels before cleaning?

Turning off your solar panels helps to avoid any risk of electric shock and ensures that you won’t accidentally short-circuit your system. Most solar systems have a designated shut-off switch or breaker that you can use to safely power down your panels before you begin cleaning.
