Solar Panel Cleaning
Dirty panels lose power — Even a light layer of grime can cut efficiency by 10–25%, and heavy build‑up can push losses past 30%.Rain doesn’t clean panels — Rainwater leaves mineral spots, pollen, and dirt streaks. It’s like never washing your car because “it rains”
Annual cleaning boosts output — Most UK installers recommend 1–2 cleans per year to maintain warranty and peak performance.Faster ROI — A clean system can generate £50–£150 more electricity per year depending on array size.Bird mess is the #1 killer — Droppings block entire cells, causing hotspots that reduce lifespan.Safe, soft cleaning matters — High pressure voids warranties. Soft‑wash, pure‑water cleaning is the industry standard.Cleaner panels = longer life — Dirt causes hotspots, which age panels faster. Clean panels run cooler and last longer.
Homeowners can’t reach them safely — Most roofs need proper equipment, poles, and safety gear. DIY is risky and often ineffective.Pure water leaves zero residue — No chemicals, no streaks, no film — just maximum light absorption.Instant visual proof
