An estimate, not a promise — based on a typical UK yield of ~950 kWh per kWp, panels left uncleaned for 3+ years and the build-up typical of your surroundings. Pitch and shading play a part too.

PURE-WATER TECHNOLOGY

Pure water. Nothing left behind.

We purify water to 100% deionised, then lift dirt and grime on contact. It dries spotless — most importantly its the safest way to clean your panels.

WHY CLEAN REGULARLY

Clean panels work for you.

Dirt, moss and film build up faster than most people expect — and every bit of it sits between the sun and your return.

More power

Clearing grime and debris lets your panels capture every available ray.

Lower bills

Better efficiency means more of your own clean energy and less from the grid.

Longer life

Gentle, chemical-free care helps protect the surface of your investment.

Lower risk

Trained operatives, ground-based access and full insurance on every visit.
