We’re proud of the reputation we’ve built across South Wales.
Solar panels are a fantastic investment for your home or business, but when dirt, grime, and sea salt build up on the glass, their efficiency can drop significantly. Rain alone isn’t enough to wash away stubborn film, bird mess, and sticky pollen. In fact, dirty solar panels can lose up to 15–25% of their energy generation capacity over time.
Our local Swansea and Gower team uses ultra-pure water and soft-bristled, scratch-free telescopic poles to clean your solar array safely from the ground. We never use harsh chemicals, detergents, or pressure washers, which can strip protective anti-reflective coatings or damage the delicate solar cells. With regular pure water cleaning, we ensure your panels absorb maximum sunlight and deliver the energy savings you expect.
Keeping your solar array spotless is a simple, cost-effective way to get the absolute best return on your renewable energy investment.
Clearing layer-upon-layer of stubborn dirt and grime allows maximum sunlight to reach the photovoltaic cells, boosting your daily electricity generation.
Harsh chemicals, hard tap water, or abrasive tools can scratch or streak panel glass. Our pure-water process dries naturally clear without leaving chemical residues or scratches.
Coastal air across Swansea and Gower leaves a sticky salt residue on glass. Regular washing stops salt and minerals from baking onto panel surfaces and causing long-term degradation.
Using extendable water-fed poles, we clean roof-mounted solar panels safely without climbing on your roof tiles or putting unnecessary weight on your system.

Rain helps wash away light dust, but it also carries minerals and atmospheric pollution that dry into a film. Rain alone cannot remove stubborn bird droppings, lichen, or sticky salt air buildup.
No. Tap water contains minerals that leave water spots and limescale film as it dries, which blocks sunlight. Detergents can leave a sticky film that attracts more dirt. We use only 100% pure, de-ionised water.
Not at all — in fact, many solar panel manufacturers require regular maintenance using soft water and non-abrasive tools to keep warranties valid. Our pure-water cleaning methods fully align with manufacturer guidelines.
We recommend having solar panels cleaned at least once or twice a year, especially in coastal or rural areas around Swansea and Gower where salt spray, pollen, and bird activity are high.
In most cases, no. Our water-fed pole systems reach up to several storeys high, allowing us to safely and thoroughly clean your solar panels right from the ground.
