Solar Panel Cleaning by Johnny Tsunami

Dust, pollen, and moss reduce the efficiency of your solar panels. We safely clean them using soft water and the right techniques.

Why Solar Panel Cleaning Actually Matters

Solar panels only work when they’re exposed to sunlight

A dirty panel loses up to 25% efficiency

    Solar panels only work when they’re exposed to sunlight — and in the Pacific Northwest, moss, pollen, bird droppings, and roof dust can reduce your power output without you even noticing.


    • Erode roofing materials and curl shingles
    • Crack concrete and shift pavers by holding water
    • Make walkways, decks, and stairs dangerously slippery
    • Create a rotting layer on wood fencing, stairs, and trim
    • Lower curb appeal and property value

     

    What's included in our service?

    This isn’t just a surface wash. It’s a full-property moss removal and prevention process, tailored to each surface.

    The guys did a great job cleaning our roof and gutters. There was a lot of debris from the winter storms, so it took some extra effort to get everything clean. Thanks for the great job!

    Michael Crawford and his assistant Wyatt did an amazing job on an old house with a metal roof that had 8 years of delayed maintenance. They stayed nearby 2 hours over the estimated time to finish the job. We are beyond pleased. This is the second time I have hired one of your crews to do roof and window cleaning and again I am impressed with the level of experience and intelligence they bring to the job. I’m happy to recommend your company to others. Thank you!!

    We had roof/gutters cleaned, windows cleaned, outside whole house cleaned and pressure washing done. We've lived here 20 years and have never had such professional/excellent jobs done. The house looks brand new. Wish there were more than 5 stars to give this company!

    Communication was poor from the outset. We submitted a request through their website and received no response for four days. Then, without any prior notice or scheduled appointment, an estimator showed up at our home a couple of days later.

    By that point, we had already hired another company. When we informed him, he seemed confused and believed he had an appointment, which had never been arranged. He explained that his manager wasn’t sure how to handle our online request and sent him out without confirming anything with us.

    If something as basic as scheduling and communication is handled this poorly, it raises serious concerns about how they would manage actual work or resolve problems.

    I scheduled a roof and gutter service but got stood up after doing a soft wash on my roof. Poor customer service and all I heard was excuses to why they didn't show. "They were swamped!" lol
