Pivot pumps are a major energy consumer throughout the west and a perfect fit for grid-tied solar electricity. Irrigation of the adjacent fields is needed most during the height of summer, which corresponds to the peak energy production of the solar array. The pivot pumps are turned off from October through April. With a net metering agreement in place with Fergus Electric Coop, the production of the solar array during the winter months can be credited toward the energy consumption of the pumps during the summer. The power from the solar array is converted to three-phase 480-Volt AC power by an Aurora Power-One 24 kW transformerless inverter. The system is projected to produce 35,660 kWh annually, and is estimated to offset 80% of the energy demand of two agricultural pivot pumps on this Roundup ranch. Helping to keep the fields green in more ways than one!
