Solar panels convert sunlight into electricity — but when covered in dust, pollen, bird droppings, and grime, less sunlight reaches the cells. Research shows dirty panels can lose 15–25% of generating capacity, costing you money every month.
In the foothill climate around Shingle Springs, summer dust and spring pollen are especially heavy. Regular cleaning — at least once or twice annually — keeps your system producing maximum power year-round.
Our Safe Cleaning Method
- Deionized, pure water — no mineral residue or water spots
- Soft brush technique — won't scratch panel glass
- No harsh chemicals — safe for all panel brands
- Does not void panel warranties
- Quick, efficient process with minimal disruption
How Much Power Are You Losing?
- Light dust film: up to 7% efficiency loss
- Bird droppings on one panel: up to 25% loss on that panel
- Heavy seasonal buildup: 15–30% total system loss
- Annual cleaning typically pays for itself in recovered energy
Frequently Asked Questions
How often should solar panels be cleaned? +
Once or twice a year is standard. In dusty foothill areas like Shingle Springs, we recommend cleaning in spring (after pollen) and fall (before rainy season).
Will cleaning void my solar warranty? +
No — professional cleaning with deionized water and soft brushes is specifically approved by all major panel manufacturers.
Can I clean them myself with a garden hose? +
Tap water leaves mineral deposits that reduce output. Deionized water is essential for a spot-free, efficiency-maximizing clean.
