Keep panels cleaner so your system can work more efficiently.

Why Customers Choose Aloha for Solar Panel Cleaning:

  • Spot-free drying so panels stay clean longer
  • Honest scheduling based on your environment and panel location
  • Careful work around mounting hardware and wiring

Residential solar panel cleaning across Seattle and the Eastside — a surface-safe technique that keeps panels clean without harsh chemicals or abrasive tools.

Soft-Bristle, De-Ionized Water Process

Solar panel surfaces need a careful, surface-safe approach — not the same method as a window or a deck. We use soft-bristle brushes paired with de-ionized water, which lifts dust and pollen without scratching the panel surface.

The water dries spot-free, so you don’t trade one type of buildup for another after the cleaning is finished.

Cleaner Panels Let More Sunlight Reach the Surface

Layers of pollen, dust, and outdoor residue sit on solar panel surfaces and reduce how cleanly sunlight reaches them. Cleaning the panels is a simple way to keep the surface clear.

Every system is different, so we don’t promise specific output gains — but a clean panel surface is the goal, and the panels look the part too.

Best Cleaning Frequency in the Pacific Northwest

Most Seattle and Eastside homes do well with one or two solar panel cleanings per year — ideally before spring after winter buildup, and again after pollen season. Homes near tall trees, busy roads, or active construction may need a third cleaning to stay ahead of debris.

We can help set a schedule that matches your specific environment, instead of using a generic interval.

We bought a fixer-upper in West Seattle and the previous owners clearly hadn't cleaned the outside in years. Siding, windows, walkways, the whole thing looked tired.

Aloha bundled soft wash, exterior windows and pressure washing into one package and the price was way more reasonable than I expected. The transformation was huge. Two neighbors literally walked over to ask who did the work.

Family-run business that actually cares. So rare these days.

Had our solar panels cleaned for the first time in three years. Visible difference in our power output the next sunny day, my husband actually pulled up the app and showed me.

Proper soft-bristle equipment, pure water, no streaks or scratches. They also noticed one mounting bracket needed tightening, which we never would have caught ourselves.

Great value, great people. Booked them again for the fall already.

I run a small retail shop on the Eastside and the front glass and sidewalk take a beating in the winter. Aloha now comes by every six weeks. Windows cleaned, sidewalk pressure washed, entry door spotless.

They come before we open, never disturb a single customer, and the invoices are clean and easy to track. Same crew every time, which is huge for me.

If you run a business in Seattle or Bellevue and need a reliable exterior partner, these are your people.

I manage a small office building in downtown Bellevue and we've gone through three different window cleaning companies in two years. Aloha is the first one I actually plan to keep.

Quick, reliable, communicate clearly, and the work is consistent every visit. Tenants have noticed and commented on how much brighter the lobby looks. Already moved them onto a quarterly contract.

Quick response, came out the same week, did a great job on the windows before our daughter's wedding. Couldn't be happier. Thank you guys!

FAQ

Solar Panel Cleaning

Why do solar panels need cleaning in Seattle?

Solar panels can collect pollen, dust, dirt, bird residue, tree debris, and seasonal buildup. Rain helps, but it does not always remove residue that dries onto the glass surface.

How often should solar panels be cleaned in the Pacific Northwest?

Many homeowners clean solar panels once or twice a year, often after pollen season or before the sunniest months. Homes near trees, roads, or frequent debris may need more frequent cleaning.

Do you pressure wash solar panels?

No. Solar panels are delicate and should not be cleaned with harsh pressure. We use a careful, non-abrasive approach designed for panel surfaces.

Will cleaning my solar panels void the manufacturer warranty?

Cleaning requirements can vary by manufacturer and installer. We use gentle methods, but homeowners should always follow their system’s care guidelines. If your installer has specific instructions, let us know before the service.

Can clean solar panels improve sunlight exposure?

Yes. Clean panel surfaces allow more sunlight to reach the glass. The exact effect on energy production depends on weather, shading, panel angle, and the amount of buildup, so we do not promise a specific percentage increase.

Solar panels are exposed to rain, pollen, dust, leaves, and outdoor residue throughout the year. Over time, buildup can affect both how the panels look and how cleanly they receive sunlight.

Our solar panel cleaning service uses soft-bristle equipment and pure water to gently remove dirt and residue, helping panels stay clean without aggressive scrubbing or harsh chemicals.
