Solar Panel Cleaning

Solar panels collect the rays of the Sun and convert them into electricity for your home or business. The more light that is entering into the panel, the more power it will generate. However, dirt collected on the panels reduces the amount of electricity that they can produce. In some cases, this loss may be as high as 25%.

There are many factors can affect how much electricity your solar panels produce, but dirty solar panels can be one of the easiest to fix with the greatest of results.

Solar panels are often placed on the roof of a building for optimum sunlight contact. So like your roof, your solar panels are subject to the harsh elements year in and year out. Pollen, dirt, algae and mould have the ability to affect the amount of sunlight that your system can collect.

Cleaning your solar panel system is more difficult than most people think. It will take more than just a spritz of water and the use of certain chemicals can ruin the solar panel.

Cthru Windows strives in being the best at what we do, and we only use the latest and best quality equipment for the work we undertake. We have a process to effectively clean your solar panel system from the ground using de-ionized water and a water fed pole. Once we have cleaned your solar panels, you will not only see a difference in the appearance but the panels will be able to work more efficiently, generating more electricity.

Living close to the coast means my windows get covered in sand, so I couldn’t have been happier when I came home after work to gleaming windows! Aaron is professional, polite and kept me updated so I knew when to expect him. Would highly recommend. Thank you, Aaron!

Aaron has cleaned the interior of my conservatory today and I am very pleased with the end result, he worked efficiently and effectively on what was a very dirty space due to spiders. He even cleaned the floor of all the debris. Good price. Will definitely be using him again
