Do Solar Panels Need Cleaning?

Solar panels often require only minimal maintenance when installed in the UK due to the often rainfall that washes away dust and little particles. However, in certain cases deep cleaning is still required:

  • Visible build-up of grime/dirt
  • Bird droppings
  • Build-up of algae
  • Drop in solar panel output due to dirt
  • Panel tilt is less than 5 degrees doesn’t allow for efficient self-cleaning
  • Ground-mounted solar panels get dirtier more often

  • How do you avoid stepping on solar panels?

To prevent stepping on solar panels, we utilise telescopic poles to extend our reach and clean them safely without causing any damage.

  • Can you access any solar panels to clean them?

We have not yet found solar panels that we cannot access either from the ground using long reach poles, using a cherry picker or on a flat roof while attached to a Mansafe harness system.

  • What kind of cleaning products do you use?

We use purified water, which is fed through soft bristle brushes to gently remove dirt and debris from the solar panels. Chemicals are not used in our cleaning process.

  • How do you ensure the safety of your workers while cleaning my solar panels?

We take several measures to ensure the safety of our workers while cleaning your solar panels. We conduct a risk assessment before beginning any work, and we use the appropriate safety equipment and tools for the job. We provide regular training to our workers on the safe handling of equipment and materials, as well as best practices for working at height.

Professional solar panel cleaning uses the appropriate methods and equipment and therefore doesn’t damage them. We use gentle methods of cleaning,  soft bristle brushes and do not use any chemicals or high-pressure water when cleaning solar panels.
