Solar panel cleaning
For Solar panels to achieve maximum output they need to be clean. Typically, cleaning your solar panels can increase efficiency by 10-20%.
Panels can attract dirt and dust, particularly in rural areas, as well as salt and dirt particles from the wind and rain. Over time, a thin layer of dirt and grime will form, reducing the amount of light reaching the power generating cells of the panel. The effectiveness of the PV solar panel is then reduced.
No matter how big the installation, whether ground mounted or roof mounted, we have the equipment to clean your solar panels professionally and safely. It is important that this work is carried out by a professional. Solar panels can be difficult to access and are often mounted on a roof. They also need to be cleaned with the right products and at the right temperature to avoid damage and product warranty validity.
Maintaining clean solar panels will benefit in a more efficient output and prolong the lifespan of your system.
Most solar PV systems will run effectively for many years. If your solar panels aren’t performing as expected, please call us on 01226 763 127 to arrange a maintenance visit.
