Solar for agriculture

Diesel pump to solar.

Centre-pivot irrigation with the pump converted from diesel to solar. We size the array, the drive and the structure to the pump, not the other way round.

  • 50 HP steps
  • 16 to 18 hours a day

Package range

Ten packages, 150 to 600 HP.

Pick the pump duty. Packages run in 50 HP steps, and the pivot class follows the pump.

Pivot size sets the pump duty, so the classes shown are indicative until the hydraulic survey fixes it.

Before and after

Same field. Different fuel.

The pivot keeps turning. What changes is what drives the pump: a solar array and drive in place of the diesel engine and its fuel runs.

Duty before panels

The pump runs 16 to 18 hours a day.

That is why the duty assessment matters more than the panel count. The array carries the daylight hours; the rest of the run needs storage or the existing generator.
