Solar Farm Cleaning — Frequently Asked Questions

Solar farms are typically cleaned on an 18–24 month cycle, driven by output depreciation and/or warranty and O&M commitments. Solar Wash works with asset owners and O&M providers to schedule cleaning at the right time for your farm.

Solar Wash uses the Sunbrush TrackFlex system — a multi-brush unit mounted on tractors that cleans at an average rate of 15,000 to 75,000 panels per day depending on farm layout. The system uses softened water and specialist brushes that are safe for all panel types. For drone thermal inspection, we partner with Elite Drone Services Australia to identify underperforming panels, hotspots and faults.

Solar Wash uses only softened water — no chemicals, no detergents, no abrasives. This protects panel warranties, panel coatings and the surrounding environment. Our water is treated on-site using specialist filtration equipment.

Solar Wash provides solar farm cleaning services across NSW, ACT, VIC, QLD and SA. Our national team mobilises to site — all mobilisation costs are included in our per-panel pricing. Contact us to discuss your farm location and we will provide a site-specific proposal.

Every Solar Wash solar farm clean includes a detailed post-clean condition report covering block-by-block cleaning records, drone thermal imaging results identifying hotspots and underperforming cells, fault identification and recommendations, before and after soiling comparisons and a maintenance schedule recommendation. Reports are provided in digital format and can be formatted for O&M provider requirements.

Solar farm cleaning is priced on a per-panel basis and depends on farm size, location, layout, access conditions and cleaning frequency. Solar Wash provides fully inclusive per-panel pricing — no hidden mobilisation or setup costs. Contact us for a site-specific proposal and we will respond within one business day.
