Solar Panel Cleaning in Lumiar

Lumiar has been building for years, and the panels on its newer blocks show it. Every plot under construction between Alta de Lisboa and the Quinta dos Frades sends up a fine mineral dust that carries on the wind and settles on the nearest roofs, and unlike garden dust it goes hard on the glass once a damp night gets to it. Recent buildings here often come with solar thermal collectors for the hot water as standard, and increasingly photovoltaic arrays wired for the whole block, all of it on accessible roof terraces. Arranja Já comes out to wash those installations and to organise the visit with whoever runs the building.

About our service in Lumiar

Where the array serves the block, the roof is common property and the work is a condomínio matter, so our first call is to the building manager. We agree the day, how the terrace is reached, whether the service lift can carry kit and how residents will be told. When the panels are a single household's on a private terrace, you book directly, though access through the building still has to be arranged. Getting that settled beforehand is what keeps a job to a single visit. The cleaning is deliberately gentle, and construction dust is exactly why. Once it has bonded, the temptation is to attack it, and attacking it is what ruins panels. So: demineralised water in quantity, a soft brush, controlled water pressure, and a second soak rather than more elbow. High pressure never comes out, because forced water finds the frame seals and behind them sits the wiring. Nothing abrasive touches the glass, because the anti-reflective layer is thin and, once scoured, gone. No acidic or alkaline cleaners either. Beyond the physical damage, cleaning a module aggressively is one of the surest ways to lose the manufacturer's warranty. Demineralised water has the added merit of drying without limescale marks, which mains water leaves plainly visible on dark modules. We choose the hour with the heat in mind. Cold water on glass that has been in full sun is a thermal shock and a route to micro-cracks in the cells, so Lumiar roofs get done early in the morning, at the end of the afternoon, or under cloud. With the rows rinsed we wipe the frames, clear the terrace drainage and pull the grit, leaves and feathers out from beneath the modules. Then we tell you what we found. A cracked pane, a delaminating cell, heat marking or a scorched connector is photographed and handed straight back to you for your installer or a certified electrician to deal with. We do not open the inverter, touch the DC side or lift a module: we are cleaners, and pretending otherwise would not help anyone.

Frequently Asked Questions

Questions we are asked in Lumiar:

There is still building work going on next door. Should we wait before cleaning?

Often yes, if the heavy work is nearly done, because a wash straight after it lasts far longer. If the site has months to run and the array is visibly coated, it is better to clean now and again at the end rather than leave dust to bond over a whole season.

Who pays when the array belongs to the whole building?

That is settled inside the condomínio, not by us. We quote the work to the building manager and they handle it the way the building handles any common maintenance. What we can do is quote the whole roof in one go, which is generally simpler for everyone.

Can you tell us whether our inverter is working properly while you are up there?

No, and we will not pretend to. We look at the glass, seals, frames and fixings and report anything visibly wrong. Anything to do with the inverter, the wiring or the protections is for your installer or a certified electrician, and we say so rather than guess.
