Solar Panel Cleaning in Amadora

About our service in Amadora

The deposit on an Amadora terrace is less dust than grime: fine soot bound in a trace of oil, which is why a hose alone slides over the top of it. It comes away with water, time and a soft brush, in that order. We soak the modules in demineralised water, wait for the film to loosen its hold, then work each pane at a low, steady pressure, going round twice where build-up is heavy beside a parapet or flue. What never happens is escalation. No pressure lance, because water at that force gets in behind the frame gasket, and the junction box and cable tails are on the other side. No pad, wire wool or paste, because the anti-reflective coat is a surface treatment and once dulled it stays dull. No acidic or alkaline cleaner. Any of the three can also void the module's warranty. Shade is the conversation we have most often here. On a dense street the shadow of the block opposite tracks across an array for part of the day, and a lift overrun, a water tank or a flue on your own roof does the same thing. Washing does not touch any of it. Dirt shades cells and so does a building; the difference is that only one of them can be removed. Where shading is permanent it is a limitation of where the panels were placed, and that complaint belongs to whoever designed the layout, not to a cleaner. We also decline to put a number on what a clean is worth. What we will say is that one localised patch of soiling can hold a whole string back through hot-spot behaviour, and that your own monitoring app, read before and after on comparable days, is the only honest measure. Access is arranged before we arrive. Where the installation belongs to the building, whether a shared array or collectors feeding the hot water, the roof is common property, so the date, the door and the notice to residents go through the building manager. Where it is one flat's own, you book it directly and we still agree the route up. Then the hour is chosen with heat in mind, since these terraces turn fierce by mid-morning and cold water on hot glass is a thermal shock that can crack cells microscopically. Early, late, or under cloud.
