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.

    JP was able to take a look at a couple of clogged downspouts on the same day I called to schedule an appointment. Not only that, but he took the time to clear them out while he was here, explain what caused the issues, and make recommendations for downspout & gutter upkeep and roof maintenance. Outstanding service and highly recommend!

    Good work, Dylan! Dylan's work definitely shows. Both the house & shed roofs are so clean now. The house's 30 year roof is 20 years old. As I looked today, it looks like a new roof! And he cleaned ALL the windows. It's so nice to look outside through them.

    Johnny Tsunami has serviced the roof and siding of my house for years. If they weren't an exceptional business I wouldn't use them again nor write this review. JP listened carefully to what I wanted and then assessed what the house did/didn't need. Within a week Alex spent 4+ hours meticulously blowing, scraping, and soft washing the roof. He did this in very cold lightly raining weather! The roof looks great and its life has been extended.

    The gentleman named Jack. Did an amazing job for us. Our roof looks new again. All the peaks in the roofs had moss control on them and all the leaves and branches were cleaned off and taken away. Very pleased with this young man’s service. Thank you Jack!
