Do Solar Panels Need to Be Cleaned?
In most parts of the country, panel cleaning is heavily marketed as a necessary maintenance item.
In New England and the Mid-Atlantic, it isn't.
Here's why:
Rain Handles It
The region gets consistent rainfall throughout the year, which naturally rinses:
- Dust
- Pollen
- Debris
Off the smooth panel surface.
What Studies Show
Studies on panel soiling in high-rainfall climates consistently show that the production gain from cleaning is too small to justify:
- The cost
- The risk of getting on your roof
The Snow Exception
If your panels are covered in snow, you don't need to clean them — but you also don't need to rush to clear them.
Panels shed snow naturally as they warm up, and a day or two of coverage has minimal impact on your annual production.
See [[solar-in-winter|Solar in Winter]] for more detail.
If You Notice Significant Debris
Examples:
- Bird droppings concentrated in one area
- Leaves stuck after a storm
What to do:
- ✓ Gentle rinse with a garden hose from the ground
- ✓ Let rain handle routine cleaning
What NOT to do:
- ❌ Pressure washers (can damage panels)
- ❌ Soaps or chemicals
- ❌ Getting on the roof
Bottom Line
In our service area, panel cleaning is not something you need to budget for or schedule.
Your system is designed to perform without it.
