Solar panel cleaning and window washing, twice a year
Dust, pollen and smoke settle on rooftop panels and windows all year. We rinse them with pure water from the ground, on a route through your neighborhood, every spring and fall.
- From $249 a visit on the twice-yearly plan, panels and outside windows
- Pure water, soft brush, no soap and no pressure washer
- No contract. You don’t need to be home
Solar panel cleaning, start to finish
The same visit takes care of your panels and the outside of your windows. Most homes take one to two hours.

Your route day
We clean streets on set days, so we email you a date. You don’t need to be home; we need the side gate open.
-
Panels, from the ground
A soft brush on a long water-fed pole and purified water. If a roof can’t be reached from below, we tell you before we start.
-
Windows outside
Glass, frames and sills. Purified water dries without spots, so nothing is wiped by hand.
-
Six months later
On the plan we come back for the next season and email you the date first. Skip or cancel any time.
What builds up on Bay Area panels
Rain does little in a dry year. These are what we wash off most.
-
Summer dust
Months without rain leave a dull film, worst near freeways, farms and building sites.
-
Spring pollen
Oak and pine pollen sticks once morning dew dries on it.
-
Bird droppings
A single spot shades the cells under it; dried ones need soaking, not scraping.
-
Wildfire smoke and ash
Smoke days leave an oily grey haze on glass that rain alone doesn’t lift.
How much power you get back depends on how dirty the panels were, so we don’t promise a number. If your solar app shows daily production, compare the week before our visit with the week after.

Solar panel cleaning questions
Do you walk on my roof?
Usually not. We clean from the ground with a soft brush on a long water-fed pole, which reaches most one- and two-story roofs. If your panels can only be reached from a ladder or the roof, we tell you and agree the price before we start.
Do I need to be home?
No. We need the side gate unlocked and an outdoor tap we can use. We email you when we’re done.
What do you clean with?
Purified water and a soft brush: no soap, no chemicals and no pressure washer. Purified water has no minerals in it, so it dries without spots on panels and glass.
Will cleaning affect my panel warranty?
Most panel makers ask owners to clean with plain water and a soft brush and to avoid pressure washers and harsh chemicals. That is how we clean. Check your own warranty if you are unsure.
How much more power will I get?
It depends on how dirty the panels were, so we don’t promise a number. If your solar app shows daily production, compare the week before our visit with the week after.
Why twice a year?
Spring brings pollen and summer brings dust and smoke; the rains rarely wash it all off. A spring and a fall visit keeps the film from building up through the sunniest months.
What does solar panel cleaning cost?
From $149 for up to 20 panels, $7 for each extra panel. Panels and outside windows together are from $279, or from $249 a visit on the twice-yearly plan. We send the exact price by email before we come.
Is there a contract?
No. The plan is two visits a year, you pay after each visit, and you can skip or cancel by replying to our email.
Do you clean inside windows?
Not yet. We clean the outside glass, frames and sills.
Where do you work?
We are starting in the East Bay, the Tri-Valley and the South Bay. A route opens on a street once enough neighbors sign up; send the form and we’ll email you when a route reaches you.
