Why Solar Panel Cleaning Actually Matters
Why House Washing 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
You don’t need a repaint or a remodel. You just need a professional house wash — done the right way.
