How often should solar panels be cleaned in Colorado?

2–4 times per year is ideal. After pollen season in spring and after summer monsoons are the most impactful cleaning times.

Does cleaning void my solar warranty?

No. We use manufacturer-approved methods (deionized water, soft brushes) that comply with all major panel manufacturer guidelines.

How much efficiency can I recover?

Heavily soiled panels typically see a 15–30% efficiency improvement after cleaning. Even moderately dirty panels often gain 5–10%.
