A dirty array is a slow leak in your investment

Solar panels are designed to work in the sun — not under layers of dust. Across Pretoria, Centurion, Midrand and the rest of Gauteng and surrounds, pollution, pollen, construction dust and bird droppings build up far quicker than most people realise.

Why it pays to clean

Increased energy output

Clean panels absorb more sunlight, helping your system produce the power it was designed to generate.

Extends system lifespan

Built-up grime creates hot spots that can shorten the life of your panels. Regular cleaning helps protect your investment.

Lower electricity bills

More production means buying less electricity from the grid and getting more from the system you've already paid for.

Professional equipment

We use specialist brushes and a safe cleaning method that works effectively without scratching the glass or damaging protective coatings.

Since our panels have been cleaned, our solar generation have been 32% higher. Great and trustworthy team — I should have done this much sooner! We forget how much dust our panels accumulate.
