How we clean panels
It's the same water-fed pole system we use on windows. A soft brush loosens the dust, pollen, and bird droppings, and filtered water rinses it off and dries without spots. Sap and droppings get a longer soak. We never scrape the glass or put a pressure washer on panels.
From the ground or the roof
Most arrays can be reached from the ground or from a ladder at the roof edge. If we do have to go up, the tech is in a harness and tied off, and steps only on the roof, never on the panels.
How often
Once a year is enough for most homes. Twice if you're near a dirt road, new construction, or a lot of trees, or after a summer with heavy smoke. If your monitoring app shows output dropping and the weather hasn't changed, dirty panels are one thing to check.
What we look for while we're there
- Cracked glass
- Loose or hanging wiring
- Birds or squirrels nesting under the array
We send you photos. We're not solar techs, so anything electrical goes to your installer.
Price
Most home arrays run $149 to $349, depending on how many panels there are and whether we can reach them from the ground. Panels on a steep or third-story roof cost more because of the setup.
Solar questions
Will cleaning void my panel warranty?
Soft brushes and filtered water are what most panel makers recommend. Pressure washers and harsh soap are what cause problems.
Can you do the panels and windows on one visit?
Yes, and it costs less than two separate trips.
Do I need to shut the system off?
Most installers suggest switching it off at the inverter while panels are cleaned. It takes a minute, and we can walk you through it.
