Solar panel cleaning in Alicante
Alicante tap water carries 199–362 mg/L of dissolved minerals. Rinse panels with it and you swap calima dust for a lime film. We wash with soft brushes on a 12 m carbon pole and finish in 0 ppm water, so the glass dries clear. Flat-roof arrays in the city and tiled-roof arrays in San Juan and El Campello are both covered; while we're up there we can rinse the roof terrace too.

Alicante is the biggest town we cover, with 365,586 residents and about 3,096 registered tourist rentals. Calima and mud rain hit the area in November 2025 and again in March and April 2026, and each time the mud dried hard onto panel glass.

Common questions
Why does cleaning solar panels matter?
Saharan dust (calima), sea salt and limescale from hard water leave a film on the glass that scatters light. Panels produce less well before they look dirty. Cleaning removes that film.
How do you clean the panels?
With demineralised water, which dries without limescale, so there's no scrubbing and no scratches on the glass. We use a soft brush on a telescopic carbon pole and never step on the panels.
Do you use chemicals? Does cleaning affect the panel warranty?
No detergents and no pressure washer on the panels, just demineralised water and a soft brush on a pole. That's the cleaning manufacturers usually ask for, so it shouldn't cause warranty problems.
How often should solar panels be cleaned?
On the coast, a few times a year, plus an extra clean after heavy calima. The dust sticks to the glass once the dew settles, and rain rarely washes it off.
How much output does a dirty solar panel lose?
It depends on how dirty they are, their tilt and how long since it last rained, so we won't give you a made-up percentage. The best way to know is your own inverter app: compare output for a few days before and after the clean, in similar weather.
