Solar panel cleaning for St. George homes
Solar panel cleaning removes the dust, pollen, bird droppings, and water spots that build up on panels in the desert. In the St. George area, dust storms and dry months mean panels get dirty faster than in many places. A local crew cleans them with soft brushes and filtered water, without harsh soap or pressure washing.
Signs your panels need cleaning
- You can see a film of dust or spots from the ground or an upstairs window.
- Your monitoring app shows output lower than the same month last year with similar weather.
- Birds have been roosting on the roof or under the panels.
- It has been a year or more since the last cleaning.
How it works
- You call or send the short form with your roof type and about how many panels you have.
- A local cleaner confirms access and gives a price.
- On the day, the crew cleans with a soft brush and filtered water, then checks for obvious damage or nesting.
- Many people set up a repeat schedule once they see how fast dust comes back.
An honest note on output
Clean panels can capture more light than dirty ones, but nobody can promise a set increase in power. Results depend on how dirty the panels were, the season, and your system. Your monitoring app is the best way to judge the difference.

Common questions
How often should solar panels be cleaned in St. George?
Many homeowners clean once or twice a year. Homes near construction, open desert, or busy roads, or that see a lot of birds, may want it more often. Check your monitoring app for a pattern.
Does rain clean solar panels?
Light rain often leaves dust behind as spots, and the desert does not get much rain. A rinse with hard tap water can also leave mineral spots, which is why cleaners use filtered water.
Can I clean my own panels?
You can with a soft brush and clean water from the ground, but getting on the roof is risky and some cleaners or abrasive tools can damage panels or affect the warranty. Check your panel maker's guidance first.
Will cleaning void my warranty?
Gentle cleaning with soft brushes and water is normally what makers recommend. Harsh chemicals, abrasive pads, and pressure washers are what to avoid. Check your warranty terms.
Do you also handle birds under the panels?
Pigeon guards (mesh around the panel edges) are a separate job. If you mention birds in your request, we ask whether the local company offers it.
How long does a cleaning take?
A typical home system takes an hour or two, depending on the number of panels and roof access.
