Solar Panel Cleaning Services That Save You Money
Consistent professional solar panel cleaning offers numerous benefits for your system's efficiency, longevity, and the overall return on investment of your Portland home's energy setup.
Maximized Energy Production — regular cleaning removes the "hard shading" caused by bird droppings, pollen, and dust that can reduce energy output by up to 25%, putting money back in your pocket immediately.
Protection from Damage — neglecting your panels allows debris to create "hot spots" (localized overheating) which can burn out solar cells and permanently shorten the lifespan of your expensive array.
Warranty Compliance — most manufacturers require regular cleaning to maintain your warranty, but using the wrong chemicals or pressure washers can void it. We use manufacturer-approved pure water methods to keep you protected.
Enhanced Curb Appeal — a dirty, mossy solar array makes your entire roof look neglected. Cleaning them restores the sleek, modern look of your home and signals that the property is well-maintained.

Your Questions, Answered
-
No. Rain doesn't clean solar panels any more than it cleans your car windshield. In fact, rain often makes it worse. It traps pollen, dust, and bird droppings against the glass, creating a "mud layer" once it dries. This grime blocks sunlight. To get maximum efficiency, the glass needs to be scrubbed and rinsed with purified water, not rain water.
-
Industry data shows that dirty solar panels in the Pacific Northwest can lose 15% to 25% of their energy output. That is free electricity you are throwing away. If your system saves you $200/month, a 20% loss is costing you $40/month. A professional cleaning usually pays for itself in restored energy production within a few months.
-
Yes. Most of our clients see an immediate spike in their monitoring app (like Enphase or SolarEdge) the very next day. We remove the opaque film of pine pollen and lichen that plagues Happy Valley roofs, allowing the cells to absorb full UV spectrum again.
-
No. Solar panels are not designed to bear human weight. Walking on them causes invisible "micro-cracks" in the photovoltaic cells that permanently ruin efficiency. We use long-reach Carbon Fiber Poles to clean your array safely from the ladder or the roof deck, never stepping on the glass itself.
-
We recommend once a year, ideally in late Spring or early Summer (May/June).
Why? Oregon has a heavy "Pollen Season" in April. If you clean them in June, you remove that yellow pollen layer right before the sunniest months of the year (July–Sept), ensuring you capture maximum energy during peak production season.
-
Yes. This is the most cost-effective way to do it. Since we are already on-site with our water filtration equipment, we can add a Solar Panel Clean to your window cleaning package for a significantly reduced rate compared to a standalone visit.
