Commercial Solar Panel Washing

Clean The Dirt Away & Let The Sunshine In

Maximize Solar Efficiency with Regular Cleaning

Like your roof, your solar panels are one of the least inspected parts of your building and as such can be neglected when it comes to cleaning.

While we can rely on rain to clean them to a certain degree, over time the weather takes its toll. We recommend an annual wash of all solar panels to ensure they stay in good working order and don’t deteriorate over time.

Why Wash Your Solar Panels?

Like your roof, your solar panels are one of the least inspected parts of your building and as such can be neglected when it comes to cleaning. While we can rely on rain to clean them to a certain degree, over time the weather takes its toll. We recommend an annual wash of all solar panels to ensure they stay in good working order and don’t deteriorate over time.

  • Over time dirt, dust and grime will build up on the panels and left unwashed could start to damage them. Regular washing can help keep your panels in good working order.

  • Some manufacturers require regular cleaning to retain the warranty on the panels.

  • The build-up of dirt can affect the efficiency of your solar panels, meaning they will be generating less power. Regular cleaning can help to ensure your solar system runs as efficiently as possible.

  • Panels should be installed at an angle of over 10% to ensure rainwater assists with keeping them clean, but in many cases due to roof and solar system design, this is;’t achievable. If this is the case a regular clean is a necessity.
