Solar Panel Cleaning in Algueirão-Mem Martins

About our service in Algueirão-Mem Martins

On a wooded plot, half the job is what has gathered where nobody can see it. Leaves and seed cases blow in under the array, jam against the clamps and rot down into a damp mat that holds moisture against the frame and chokes the gutter at the eaves. All of that comes out by hand before any water goes on. It matters for a reason owners rarely expect, too: a clump of litter lying on the glass is not a cosmetic nuisance but a localised shaded patch, and localised shade is what produces hot-spot behaviour, where one poorly lit cell drags the output of an entire string down with it. Even dusting across a whole panel is a mild loss by comparison; a single dropping or a stuck leaf is the thing worth going up for. Then the glass. Generous demineralised water first, left long enough to loosen what has bonded; a soft brush next, with the water pressure held down; and a second soak for anything reluctant rather than harder work. Three things stay out of the process, each for a good reason. A pressure lance, because water thrown at a frame edge travels past the seal towards the cabling. Anything abrasive, because the thin anti-reflective coat on the glass does not survive scouring and never comes back. Anything acid or alkaline, because it strips that same coat chemically. All three are also a straightforward way to lose the manufacturer's warranty, which is a poor exchange for a stubborn mark. Getting up there is its own decision on a house. Tile is not built to be walked on carelessly and modules least of all, so the ladder goes up properly, a harness is clipped to an anchor line, and our feet stay on the roof structure or on boards. Where the array sits low enough, a pole worked from the ground or from a flat section keeps us off the roof altogether. One roof type we turn down: the old grey corrugated sheeting still common on garages, sheds and rear extensions around here is brittle with age and may contain asbestos, so we do not walk on it. We find another route to the panels, or we say honestly that it cannot be done safely.
