Solar Panel Cleaning in Carcavelos

About our service in Carcavelos

Grit is the reason we are so insistent about method here. Sand on glass and a brush pushed hard is essentially sandpaper, and the anti-reflective coating on a module will not survive that treatment. So the sequence is always the same: wet the surface generously with demineralised water first, let the deposit float rather than drag, then bring a soft brush through at controlled pressure and rinse. Never a pressure washer, because high-pressure water at a frame joint can pass the seal and reach the electrical connections behind the module. Never an abrasive, never a scraper, never an acidic or alkaline cleaner. Aside from ruining the surface, aggressive cleaning gives a manufacturer every reason to reject a warranty claim on the array, which is a poor outcome for the sake of finishing an hour sooner. Demineralised water is not a luxury on a coastal roof. Mains water dries into limescale spotting, and on dark glass those spots are visible and become the seed for the next layer of grime. Demineralised water dries off clean. Timing is fixed by the heat. We do not put cold water on glass that has been in the sun since morning, because thermal shock risks micro-cracks in the cells, so Carcavelos jobs are booked for early morning, late afternoon, or a cloudy day. The access decision comes before anything else. Villas usually take a ladder with a harness and anchor line, or a platform; a shared block roof is often walkable and simpler; and where rows sit low, a telescopic pole from the terrace does the job with nobody on the roof at all. We do not stand on the modules and we do not encourage anybody to climb up for a look. Old corrugated fibre-cement roofing on a shed or garage is a hard no: it is brittle and may contain asbestos. We finish by taking the sand out of the frame channels and from beneath the rows, clearing the drainage, and reporting on the state of the glass, seals and clamps. Anything electrical, from a scorched connector to a chafed cable, is photographed and referred to your installer or an electrician.
