  • 2000 m²/h
  • 30° Gradeability
  • Twin 1.4 m Brush
  • IP65

The SR203 is the machine for difficult ground: 30 degree max inclination, a 400 mm horizontal gap and a 50 mm step, with twin 1.4 m roller brushes that clean 2000 m²/h. If the array is on a hillside and the access road is too narrow for a crane, this is the version that keeps working.

Best for: Steep 30 degree terrain and wide module rows, the hardest ground-mount geometry in the range

When to Choose This

The machine for difficult ground. 30 degrees of inclination, a 400 mm horizontal gap, a 50 mm step and twin 1.4 m brushes cleaning 2000 m²/h.

Choose SR203 when:

  • The array is steep, hillside or badly terraced
  • Rows are wide and the terrain is also steep
  • Access is too narrow for a crane or a rope team

Choose something else when:

Need Choose Why
Flat ground, light handling SR102 32.5 kg, 15 degrees
Unattended operation ASR102 autonomous, but 10 degrees only

Why It Is the Heaviest

At 44.5 kg with battery and both 1.4 m brushes fitted, the SR203 is the heaviest machine in the range. It carries that weight for two reasons: a wider brush than anything else here, and the chassis that climbs 30 degrees. Battery endurance drops to 5 hours with two brushes drawing power.

Where It Fits

  • Utility-scale ground-mount plants on a fixed cleaning cycle
  • Mountain and fishery-solar hybrid sites with sloped or steep arrays
  • Commercial and industrial rooftop arrays, in dry sweeping mode
  • Plants replacing manual washing crews and rope access

Compatible Equipment

PV modules on standard frames, a 100 m water supply for wet cleaning, 4G cellular coverage for the autonomous ASR102, and a prepared charging station pad for its unattended mode.
