Why panels get dirty in El Cajon
- Valley heat bakes dust and grime onto the glass.
- Dry hills and open land send dust into the air on windy days.
- Ash from regional fires can settle on panels.
- Hard tap water from a hose leaves mineral spots.
The hotter valley sun means more power from your panels, as long as the glass stays clear.

El Cajon FAQ
How often should panels be cleaned in El Cajon?+
Many El Cajon homeowners choose 2 to 3 visits a year. There's no contract, so you can adjust anytime.
Can I just hose my panels off myself?+
You can, but hard tap water often leaves white spots, and climbing on a roof carries real risk. Deionized water rinses clean without spotting.
Do you also clean windows?+
Yes. The same dust that coats your panels ends up on your windows, and we offer exterior window cleaning on the same visit.
