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.

    Crew Icon Soft-Water, Brush-Free Cleaning System

    We use a purified water-fed pole system that cleans panels without pressure, brushes, or abrasive chemicals.

    Brush Icon Streak-Free, Spot-Free Finish

    Because we use mineral-free water, your panels dry crystal clear — no streaks, no spots, no haze.

    Swords Icon Roof-Mounted or Ground-Based System Cleaning

    Whether your system is mounted on your roof, garage, shed, or in your backyard.

    Swords Icon Full Site Clean-Up

    We rinse any overspray, roll up hoses, and leave your roof, driveway, or yard exactly how we found it — but cleaner.
