Solar Panel Cleaning Equipment — Commercial & Agricultural Arrays

Solar panel cleaning is a growing specialist maintenance sector driven by the rapid expansion of rooftop commercial arrays, ground-mount solar farms and agricultural solar installations across the UK. Soiling — bird fouling, dust, algae, pollen and lichen — reduces panel output by 5–25% depending on location and season. Regular cleaning maintains generation efficiency and protects the asset. V-TUF supplies the pressure washers, pure water systems, battery-powered equipment and bowser units that solar panel cleaning contractors use for rooftop, ground-mount and agricultural array maintenance.


The cleaning specification for solar panels

Solar panel manufacturers specify low-pressure pure water or deionised water cleaning to avoid panel damage, voiding warranty and leaving mineral residue from mains water. The correct specification is:

  • Low pressure — excessive pressure (above 40-60 Bar for most panel types) risks micro-cracking, seal damage and water ingress. A pressure washer with adjustable pressure or a dedicated low-pressure setting is required.
  • Pure or deionised water — tap water leaves calcium and mineral deposits that attract soiling and reduce efficiency. Deionised water (DI) or reverse osmosis (RO) water with a TDS meter to verify quality is standard for commercial solar cleaning.
  • No chemical detergents — detergent residue on panels attracts dust and may react with anti-reflective coatings. Water-only cleaning is the correct specification for most panel types.
  • Battery or generator power — ground-mount solar farm sites and rooftop arrays frequently have no mains power supply at the point of cleaning. Battery-powered or petrol/diesel equipment is required.

Equipment specification

Battery pressure washers — no mains required

V-TUF TUFJET 4 — 110 Bar, 11 L/min, 2 x 82V lithium

Battery-powered pressure washer with adjustable pressure for solar panel cleaning at the correct low-pressure specification. No trailing mains cable — fully self-contained for rooftop and ground-mount deployment. Two 82V batteries and double charger included.

Bowser pressure washers — self-contained water supply

V-TUF TORRENT 2H — 150L bowser, Honda GX200, 160 Bar

Self-contained mobile unit with 150L onboard water tank — for ground-mount solar farm sites with no mains water supply. The tank can be filled with deionised or RO water at the depot and transported to site, eliminating the need for a separate water supply at remote solar installations.

V-TUF TORRENT 2LI — 150L bowser, battery-powered

Fully electric battery bowser for solar farm cleaning without petrol fuel handling — the zero-emission specification for solar cleaning contractors operating on environmentally sensitive sites.

Electric pressure washers — rooftop and building-mounted arrays

V-TUF V Range and tufJET — 240V electric

Where mains power is accessible on rooftop installations, compact electric pressure washers with adjustable pressure settings are the standard rooftop specification.

Solar cleaning contractor applications

  • Commercial rooftop arrays — warehouse, logistics hub, industrial unit and retail rooftop PV installations. Access via MEWP or rope access — battery equipment eliminates cable management at height.
  • Ground-mount solar farms — utility-scale and commercial ground-mount installations. Remote locations with no mains power or water. Bowser specification with DI water payload.
  • Agricultural solar — agrivoltaic installations on farm land. Combine with agricultural yard cleaning equipment for efficient on-farm maintenance visits.
  • Building-integrated PV — roof tiles, facades and canopies. Low-pressure specification critical to avoid damage to building envelope.
  • Car park canopy arrays — commercial car park solar canopies. Ground-level access but often no nearby water supply.

Working at height — compliance

Solar panel cleaning on rooftop installations is work at height under the Working at Height Regulations 2005. Risk assessment, appropriate access equipment and fall protection are legal requirements. Battery cleaning equipment removes trailing cable trip hazards on roof surfaces.
