The Process
What's included
Visual inspection
We check panel condition and mounting before starting and flag anything unusual.
Deionized water & soft brushes
Purified water and panel-safe brushes remove dust, pollen, and residue without scratching or leaving mineral spots.
No harsh chemicals
Nothing that could damage coatings or void your panel warranty ever touches your system.
Spot-free finish
Panels are left streak- and spot-free so nothing shades your cells.
Why It Matters
More than just a clean look
Dirty panels cost you money
Dirty panels produce noticeably less energy — dust, pollen, and grime are literally costing you money on your electric bill every month. Regular cleaning restores that lost production and pays for itself.
Protect the investment
Panels are a five-figure investment. Proper scratch-free cleaning maintains them the way manufacturers intend.
Catch issues early
Regular cleanings mean eyes on your system — cracked glass, wiring wear, and hot spots get noticed before they cost you.
FAQ
Common questions
How much production do dirty panels actually lose?
It varies with buildup, but studies and monitoring commonly show meaningful losses in dry, dusty climates like ours — often enough that a cleaning pays for itself.
How often should panels be cleaned?
Once or twice a year in Napa Valley — typically after the dry season, and after any heavy ash or pollen events.
Can't rain clean my panels?
Rain rinses loose dust but leaves mineral spots and doesn't touch grime, pollen film, or bird droppings. Panels in our dry climate can go months with no rain at all.
Will cleaning scratch my panels or void the warranty?
No — deionized water and soft brushes are the manufacturer-recommended method. We never use abrasives, harsh chemicals, or high pressure on panels.
