Advanced Thermal Drone Inspection

PWB Exterior Cleaning uses advanced thermal-drone technology to inspect solar panels safely from the air where conditions allow. Thermal imaging can highlight unusual temperature patterns and potential hotspots that may not be visible from the ground, helping property owners identify panels that may require further assessment.

Where concerns are identified, we can provide thermal and visual images for your records and recommend that the system is assessed by a qualified solar technician or electrician. Thermal imaging is an inspection tool and does not replace electrical testing or professional fault diagnosis.

  • Thermal and high-resolution visual imaging
  • Helps identify potential hotspots or unusual temperature patterns
  • Safer inspection of difficult-to-access rooftop panels

    Why Solar Panels Need Regular Cleaning

    • Rain Doesn’t Remove Everything

      01

      Rain may wash away some loose dust, but stubborn bird droppings, pollen, tree sap, traffic film and organic buildup can remain on the panel surface.

    • Buildup Can Affect Performance

      02

      Dirt and organic buildup can block sunlight from reaching the solar cells. Professional cleaning helps keep the surface clear so panels can capture available sunlight efficiently.

    • Warranty Compliance

      03

      Many solar panel manufacturers require regular cleaning and maintenance as part of their warranty conditions

    General Q&A

    Yes. Rain helps remove loose dust, but it may not remove bird droppings, pollen, tree sap or other stubborn contaminants. Professional cleaning helps maintain the panels’ ability to capture sunlight.

    Clean panels can perform more efficiently by allowing more sunlight to reach the solar cells. The improvement varies depending on how dirty the panels were before cleaning and local environmental conditions.

    we clean using purified water and specialised equipment. If additional cleaning products are required for stubborn contamination, we use products suitable for solar panel cleaning and follow the manufacturer’s recommendations.

    Most residential systems benefit from professional cleaning every 12 months, although homes near trees, busy roads or coastal areas may require more frequent cleaning.

    No special preparation is required. Please ensure we have safe access to the property and keep children and pets away from the work area during the service. Although it’s not necessary to switch off your solar system, you’re welcome to do so before we arrive if you wish.
