HOW OFTEN SHOULD YOU CLEAN SOLAR PANELS?
You’ve made the switch to solar — great move! But to get the most out of your investment, there’s one important step many people forget: cleaning your solar panels. So the big question is: how often should you clean them?
🧽 The General Rule
For most homes and small businesses, cleaning your solar panels once or twice a year is enough to keep them running efficiently.
🌍 But It Depends on a Few Factors:
- Your Location
Live near the ocean? Salt buildup may require quarterly cleaning. In dusty or dry areas (like deserts), panels can get dirty faster and need more frequent care.
- Nearby Trees
If you’ve got overhanging trees, watch out for leaves, sap, or bird droppings — these can block sunlight and may call for more frequent cleanings.
- Pollution & Pollen
Urban areas or homes near factories may see more grime buildup, while springtime can coat panels in thick yellow pollen — another good reason to clean a bit more often.
🌧️ Isn’t Rain Enough?
Rain can help rinse off light dust, but it won’t clean off sticky grime or droppings. Just like your car windshield still needs wiping after it rains, so do your solar panels.
✅ Pro Tip: Monitor Performance
Keep an eye on your solar output. If you notice a drop and the system seems fine, it could be time for a clean.
Final Take
Once or twice a year is usually enough, but your local environment might mean more frequent cleanings are needed. Regular maintenance ensures your panels work at peak performance — giving you maximum savings and clean energy all year long. If you need any advises from us, please don’t hesitate to contact us.
