Why panels get dirty in San Bernardino
- Winds coming through the Cajon Pass carry dust and grit onto roofs across the valley.
- Freeway and rail traffic leave a sooty grime that holds onto more dirt.
- Santa Ana winds and fire season can coat panels in fine ash.
- Long dry stretches mean grime bakes on instead of washing off.
With this much sun, a dirty panel in San Bernardino is sunlight you already paid for going to waste, which is why regular, gentle cleaning is worth it.

San Bernardino FAQ
How often should panels be cleaned in San Bernardino?+
Many San Bernardino homeowners clean 2 to 3 times a year, often after windy stretches and after fire season. 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.
