Solar Panel Cleaning in Algés

About our service in Algés

In a building this tight the roof belongs to everyone, and that is where the job begins. Where the system serves the whole block, whether collectors feeding the shared hot water or a self-consumption array split between flats, the condomínio decides and the administrador lets us in, so the date, the keys and the notice to residents are settled with them first. Where one flat owns panels on its own terrace, that owner commissions the work, but the route up still crosses common parts and still has to be agreed. In practice the awkward part in Algés is rarely the panels: it is the last flight of stairs, a narrow hatch, and no room to swing a ladder once you are through it. Droppings need patience, not force. They bake on hard, and the only safe way off is to wet them, wait, and wet them again until they lift. So we flood the module with demineralised water, let it soak, and work it with a soft brush at a pressure barely above a garden tap. High pressure is banned outright on our vans, because water driven at a frame edge goes past the seal and into the wiring cavity behind it. Pads, scrapers and gritty pastes never appear either: the anti-reflective coat on the glass is microscopically thin, and grinding it away cannot be undone. Nothing acidic or alkaline goes on. Beyond the damage itself, a module cleaned that way gives a manufacturer easy grounds to turn a warranty claim down. Demineralised water carries one further advantage in a hard-water building: it dries clear, with none of the chalky spotting mains water leaves behind. We also turn down the middle of the day. Glass on an unshaded Algés terrace bakes, and throwing cold water at it is a thermal shock that risks micro-cracks, so appointments land early in the morning, late in the afternoon, or on a grey day. Please do not go up and try this yourself: wet panels are slippery, modules are not a walking surface, and the parapets here are low. We arrive with whatever access the building calls for, then finish by clearing the frames, the drainage outlet and the compacted debris under the rows.
