Disclosed Case Scope

The case is organised around daylight pumping and water storage rather than an assumed battery bank. The disclosed supply route covers PV, a pump controller, field protection and a pump matched through the local hydraulic review. Water source, pump curve, total head, pipe route and irrigation schedule remain site-specific inputs, not transferable performance claims.

Confidentiality and evidence boundary

The farm identity, borehole records, pump curve, field photographs and irrigation results are confidential. The page describes the disclosed equipment route and planning inputs; it does not prove a particular water yield, head, irrigation volume or operating outcome for another site.

Procurement Decision Recorded

The disclosed design route stores pumped water instead of electrical energy. A battery was left out of the published scope because the irrigation schedule could be organised around daylight pumping and a correctly sized water store.

Procurement and Site Inputs

  • Irrigation needed to be practical without daily fuel deliveries or reliance on a weak grid connection.
  • Field components had to be simple enough for routine cleaning and inspection by the site team.

Disclosed Supply Approach

  • Specified a solar pumping controller with dry-run and low-water protection, matched to the selected pump and borehole conditions.
  • Used water storage as the primary energy buffer, avoiding an unnecessary battery system for a daylight-led irrigation schedule.

What This Case Establishes

  • The disclosed planning route is daylight generation, pumping to water storage and irrigation to the farm schedule, subject to the final hydraulic design.
  • The RFQ asks for pump-controller documentation and spare recommendations for local maintenance planning; final service arrangements are agreed for the selected equipment.

Equipment Scope

  • Monocrystalline PV modules
  • Solar pump controller with protection functions
  • Project-matched submersible pump
  • Ground-mount structure, cable, and DC isolators
