Commercial & Residential Solar Panel Cleaning
Pure-water cleaning that restores energy output for homes and businesses in San José
A premium take on commercial & residential solar panel cleaning
Dust, pollen, bird droppings, and valley haze build up on your panels and quietly cut their output — sometimes by a noticeable percentage every month. Rain alone doesn't rinse that off; it just leaves streaks. Fast José & María's Premium Residential and Commercial Window Cleaning Company cleans panels the safe way: deionized pure water and soft brushes that lift grime without scratching the glass or leaving mineral spots. We clean rooftop and ground-mount arrays on homes, and larger commercial systems, throughout San José, Cupertino, Milpitas, Los Gatos, and nearby communities, at whatever time suits you best.
This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.
Every project covers the essentials
- Pure-water cleaning with no mineral spots or residue
- Soft brushes safe for panel glass and coatings
- No harsh chemicals that could affect your warranty
- Rooftop and ground-mount systems, any array size
- Bird droppings, pollen, and dust fully removed
- Ideal before peak summer production months
Four steps from first call to final walkthrough
Inspect the Array
We check panel condition and access, noting heavy soiling, bird droppings, or anything worth watching.
Rinse with Pure Water
Deionized water loosens dust and grime without the mineral deposits that tap water leaves behind.
Soft-Brush Clean
Gentle, panel-safe brushes lift stuck-on pollen and droppings without scratching the glass.
Final Rinse & Check
Panels are rinsed to a spot-free finish and we confirm the whole array is clean before we pack up.
