Dirty Panels Are Costing You Money
Utah gets over 222 sunny days a year, which makes solar one of the best investments a homeowner here can make. But dust, pollen, and bird droppings build up on panels and block sunlight the same way a dirty window blocks light from a room. Panels can lose 15 to 25 percent of their efficiency during Utah’s dry summers, and for a typical home system that can mean a few hundred dollars a year in lost electricity production. Clean panels are simply panels doing the job you paid for.
Why Deionized Water Is the Right Way to Clean Panels
I use a deionized water system as my primary method on almost every solar job. It strips out the minerals before the water ever touches your panels, so there is nothing left behind to spot or streak as it dries, no wiping needed. A squeegee comes out only when it’s needed for a spot touch-up, not as the main tool. I don’t use scrub brushes or wand attachments on panels. The wrong cleaning method can scratch the surface or void your manufacturer’s warranty, and many warranties actually require professional cleaning to stay valid.

What’s Included
- Full panel rinse and clean using deionized water for a spot-free finish
- Squeegee touch-ups only where needed, never a scrub brush or wand on the panel surface
- Safe roof access using slip-resistant roofing boots and a foam roof pitch block for secure footing
- No standing or walking directly on the panels themselves
When to Schedule
Late spring, after Utah’s dust storms and pollen season settle down, is the best time for a cleaning. A second cleaning in late summer helps you head into fall still producing at full efficiency. If you haven’t had your panels cleaned since last year, you’re likely losing money on your electric bill right now.

Frequently Asked Questions
How much efficiency can dirty solar panels really lose?
Panels can lose 15 to 25 percent of their efficiency during Utah’s dry, dusty summers. For a typical home system that can add up to a few hundred dollars a year in lost electricity production.
Will cleaning my panels void my warranty?
Improper cleaning can void a warranty, but many manufacturers actually require regular professional cleaning to keep the warranty valid. I use a deionized water process that is gentle on the panel surface.
What method do you use to clean solar panels?
Deionized water is my primary method on almost every job. It strips minerals out before the water touches your panels, so they dry spot-free with no wiping. I only use a squeegee for occasional spot touch-ups, never a scrub brush or wand.
How often should solar panels be cleaned in Utah?
Most homeowners do well with two cleanings a year, once in late spring after dust and pollen season, and again in late summer heading into fall.
