Solar PV Cleaning

Having a Solar Panel Installation installed on your roof was a brilliant investment, but in order to make sure they operate to maximum performance we recommend that they are cleaned at least twice a year. But offer contracts quarterly and monthly.

Unlike windows the panels on your roof need to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. On the roof and angled skywards the panels will attract dust and grime in a number of ways:

  • Dirt & dust deposits in the air
  • Bird and animal droppings
  • Industrial pollution in the atmosphere
  • Fumes from vehicles
  • Pollens and leaves and twigs from trees and plants
  • Moss and fungus
  • In rural areas there may be fertilizer and pesticide chemicals in the air
  • In costal ares salt deposits
  • Dirt left from the weather e.g. dirt trapped in rain drops or blown on

These layers of dirt reduce the amount of light reaching the silicon cells under the glass surface and reduce the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be.

From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerably reduce its effectiveness.

There are many ways to clean Solar Panels but through experience and knowledge we recommend the pure water cleaning system as it is the safest and most effective method of fully cleaning the panels.

A fully trained operative will use a reach-pole system in which water-fed poles attached to soft filament brushes gently but effectively clean the panels. The water is chemical free and will leave no residue on the panel surface which can happen if soap or hard water is used.

Solar Panels need to be clean in order for them to operate at their rated capacity.

Prices start from £55 for up to 16 panels on a 2 storey building. Please contact us for a quotation if your system consists of more than 16 panels or your property is more than 2 storeys high.
