Hybrid Power for Irrigation Pumping

Global Protection Systems has the pleasure of working with YellowDot Energy who have designed and built an innovative Off-Grid Solar-Diesel Hybrid Power Plant. These power plants allow the farms to pump high volumes of water while reducing diesel consumption.

YellowDot Energy themselves have installed the first system on a cotton farm in Moree NSW, the power plant allows the cotton grower to pump high volumes of irrigation while reducing diesel consumption by up to 60%.

Key features

  • Integrates power from solar PV and a diesel generator via a high capacity variable frequency drive
  • Capable of operating 24/7 in hybrid mode or during daylight hours in solar-only mode
  • Pumping up to 4ML per day during peak season
  • Electronic control system manages the generator, PV, drive output and the hybrid integration
  • DC optimised PV modules provide power control from the solar array
  • Multiple sensors and modem communications provide monitoring and remote systems control
  • Submersible three phase electric pump

Projected outcomes

  • 890 ML pumped per year Up to 4ML per day during peak season (hybrid) and up to 1.6ML per day off season (solar only)
  • Annual diesel saving 40,760L which is a 60% reduction on original diesel engine
  • Reduced annual maintenance cost

Specification

  • 70kWp of solar PV Ground mounted, north facing array
  • PV modules include Tigo DC optimisers
  • 45kW ABB Variable Frequency Drive ABB PLC control system
  • 100Ah battery UPS for control system including solar and generator charging capability
