Professional deionised-water solar panel cleaning in Paphos, Cyprus. Restore lost output from dust, pollen and bird droppings without voiding your warranty.
Paphos gets some of the strongest sun in Cyprus, which is great for solar output, but the same climate that makes solar panels worthwhile also coats them fast. Saharan dust storms, sea salt, pollen and bird droppings settle on the glass all year round, and within a few months that thin film can quietly cut your system's output well before you'd notice it on the roof. ProPest now offers a professional solar panel cleaning service for homes and businesses across Paphos, using pure water technology that lifts dirt and residue without scratching the glass or affecting your panel warranty.
Whether it's photovoltaic panels feeding the grid or a solar water heater on the roof, a clean surface is what keeps your system performing the way it was designed to.
We inspect the array first to check for loose fittings, cracked glass or wiring issues before any cleaning starts. Panels are then washed with a purified, deionised water-fed pole system and soft, non-abrasive brush heads, the same approach used on commercial installations, so there's no scrubbing that could scratch the cells and no mineral residue left behind once the water dries. We work from safe access platforms or roof harnesses depending on the property, and we always time the clean for early morning or late afternoon so the glass isn't hot enough to cause thermal shock or streaking.
Studies on Mediterranean installations show that dust, pollen and bird droppings can cut solar panel output by 15-25% over a season if the panels are never cleaned, and a heavy Saharan dust event can drop performance overnight. On a system that cost real money to install, that's a meaningful chunk of the return you're not getting. Regular cleaning protects that investment, keeps your inverter readings honest, and means you're not left wondering why your generation numbers have quietly dropped over the summer.
Our cleaning system runs on purified, deionised water, which is what stops the streaky white mineral spots that ordinary tap water leaves behind once it evaporates on hot glass. We don't use detergents, solvents or pressure washers, since harsh chemicals and high pressure can degrade the anti-reflective coating and risk voiding the manufacturer's warranty. Soft brush heads on extendable poles let us reach most residential arrays safely from the roof edge or ground, with mobile access platforms brought in for larger commercial installations.
Check your inverter app or generation meter every few weeks, if output has quietly dipped on clear sunny days with no obvious cause, dirt build-up is the most common reason. In Paphos we generally recommend a clean twice a year, in spring after the winter rains and dust settle, and again toward the end of summer, with a third visit for properties near farmland, the coast, or under trees where bird droppings and pollen build up faster.
Get in touch and we'll take a look at your system, tell you honestly whether it needs cleaning yet, and get it back to full output if it does.
