Solar Panel Cleaning Services
Professional Solar Panel Cleaning
Restore lost energy output with safe, thorough panel cleaning — serving Mill Creek, Bothell, Lynnwood, Everett and more, across Snohomish County and most of King County.
Why clean solar panels matter
Dust, pollen, bird droppings, and PNW rain spotting can quietly cut solar output by 15-25%. We use pure-water systems and the right brushes to clean safely — restoring efficiency without scratching your panels or voiding your warranty.
What's included in every cleaning
Full panel array cleaning with pure-water system
Soft brushing approved for PV panels
Frame and edge wipe-down
Inspection for cracked or shaded cells
Bird-droppings and lichen treatment as needed
Photo report on request
Our Process
How we safely clean your panels
Inspect
We check panel condition, mounting, and flag any visible damage or shading before starting.
Pre-rinse
Pure water rinse loosens dust, pollen, and bird droppings without scratching the glass.
Soft brush
Manufacturer-approved soft brushes lift the rest of the grime — no abrasives, no detergent residue.
Final rinse & report
Spot-free pure-water rinse, frames wiped, and a quick walkthrough of anything we noticed.

Popular Add-Ons
Take it to the next level
Skylight Cleaning
Have your skylights cleaned during the same visit so the roofline looks bright and consistent with your freshly cleaned panels.
Gutter Cleaning
Add a full gutter cleaning to the same visit — pine needles around the array end up in the gutters anyway.
Window Cleaning
Bundle window cleaning while we're already on site for spotless glass throughout.
Roof Cleaning
Add a roof cleaning so debris and moss don't blow back onto your freshly cleaned panels.

What Customers Say
Real reviews from happy Bellevue & nearby homeowners
"Our Bellevue panels were caked in pollen and bird droppings. Xzavier's brought them back to a deep black finish without scratching the glass. Production app is showing real numbers again."
Vanessa M.
"Smart move bundling the roof debris blow with the solar cleaning at our Bothell home. Less debris means less re-soiling. Xzavier's was efficient and the panels look brand new."
Pete S.
"Xzavier's cleaned our Mill Creek solar array and the difference in production is real. Friendly, careful on the roof, and the price matched the quote exactly. Highly recommend."
