Solar Panel Cleaning with Softwashing- Safe Solar PV Cleaning

Any man-made or organic residue or film that blocks transmission of sunlight to photovoltaic solar (or thermal) panels can substantially diminish their performance. Less light means less energy, leading to a lower return on a commercial or domestic investment in renewables.  Often the offenders are moulds, algae, and bacterial atmospheric growths that can be removed by softwashing. While rainwater is thought to keep solar panels as clean as they need to be , this is not the case. Environmental factors such as salt in seaside locations, or dust and grime from highways and railways, can decrease output dramatically. When monitoring their own vast power usage, Google proved that  regular solar panel cleaning can improve panel performance by up to 12%.

While it may seem obvious and simple to clean the panels yourself, tap water when used in isolation is not up to the task, since residues and deposits of salt and minerals on the panels are left behind after tap water treament. Using chemical free pure water these deposits can be eliminated. Old fashioned cleaning methods, like high pressure cleaning, are too violent for the technology, and will damage photovoltaic cells, and reduce the shelf-life and performance of solar panels.

When cleaning solar panels, we use a clearly defined softwashing process which brings these vital technologies back their optimum, using 0% chemicals and only pure water.

We use extendable water fed poles wherever possible, and cherry pickers to avoid needing unnecessary access to the roof.

We use localised soft brushes that offer maximum protection for solar panels.

Softwashing will bring your solar panels back to their peak, returning your investment and keeping them performing for as long as the sun keeps shining.
