Solar Installer: Initial solar panel cleaning

Pricing guide

Costs are driven by how dirty the panels are and what work is needed to restore them. Adding a protective coating, larger arrays that need extra crew or mechanical access, and after-hours attendance typically increase the overall price. Regional callout fees and the time required to complete cleaning and any curing or repeat visits also affect the final quote.

• Soiling type and severity

  Light dust or bird droppings are usually quicker to remove than heavy lichen or thick guano that need chemicals and multiple scrubs.

• Protective coating application

  Applying a hydrophobic or protective coating adds materials and careful application time, and some manufacturers may advise against coatings.

• Array size and crew or equipment needs

  Larger systems often need extra crew or hire of mechanical access equipment, which increases labour and staging time.

• Access and safety requirements

  Roof pitch, harness or ladder access, and the need for specialised fall-protection setup can extend the job duration.

• Callout timing and after-hours attendance

  Regional callout fees apply and attendance outside normal hours usually attracts higher rates.
