Solar Panel Cleaning in Lisboa

About our service in Lisboa

We work the way the panel manufacturers ask us to, and that means saying no to a few things. No high pressure: forcing water at a frame joint can push it past the seal and into the junction box, and no cleaning job is worth that. No scouring pads, no scrapers, no abrasive powder, because the anti-reflective layer on the glass is thin and once you have dulled it there is no putting it back. No acidic or alkaline detergents either. Aggressive cleaning is also one of the quickest ways to lose the warranty on an installation you paid a lot for. What we do use is demineralised water, which dries off without leaving the white limescale spotting that Lisbon tap water leaves behind, applied at a controlled pressure with a soft brush head. Timing matters as much as method. A Lisbon roof terrace in the middle of a July afternoon is genuinely hot, and cold water hitting hot glass is a thermal shock that risks micro-cracks in the cells. So we come early in the morning, late in the afternoon, or on a grey overcast day, and we will move an appointment rather than work at the wrong hour. Access is the other half of the job. Many Lisbon buildings have a usable roof terrace and a service stair, which makes life simple. Others need a ladder, an anchor line and a harness, or a telescopic pole worked from the ground where the rows sit within reach. Please do not go up yourself to have a look: wet panels are slippery and you never stand on the modules. Alongside the wash we do a visual check, clean the frames and pull out the leaves, feathers and litter that pack in underneath the rows. If we find a scorched connector, a chafed cable, heat marks, cracked glass or delamination, we photograph it and tell you to call your installer or a certified electrician. We are cleaners, not electricians: the inverter, the DC side and the protections stay untouched.
