Solar Panel Cleaning – Maximise Your Energy Output

Keep your solar panels performing at their best with Lowen Cleaning’s professional Solar Panel Cleaning service, covering homes, businesses, schools, farms and commercial sites across Cornwall and Devon.

Pollution, dust, bird droppings, sea salt and algae build-up can significantly reduce the efficiency of your solar PV system — often by 10–30% if left uncleaned. Our expert team uses industry-approved, non-abrasive cleaning methods to safely restore maximum performance.

Why Solar Panel Cleaning Matters

Solar panels work best when clean. Even a thin film of dirt or grime can block sunlight and reduce power generation.

Common issues we remove include:

  • Bird droppings

  • Sea salt and coastal debris

  • Dust, pollen and pollution

  • Moss, lichen and algae

  • Tree sap and general grime

A regular clean helps:
✔ Improve solar output
✔ Protect long-term system performance
✔ Reduce fire risks caused by debris
✔ Maintain manufacturer warranties
✔ Save you money on lost energy production
