Nevada Farm Cuts Fuel Costs with Solar Irrigation
13 Oct
Summary
- Solar-powered irrigation reduced diesel use by 16,385 gallons.
- A hybrid solar and diesel system powers irrigation for 500 acres.
- The farmer anticipates saving approximately $1 million over the system's lifetime.
In Nye County, Nevada, Railroad Valley Farms has adopted a hybrid solar and diesel system to irrigate 500 acres of alfalfa, achieving a substantial reduction in diesel fuel consumption. This innovative approach was implemented because the farm, situated at a high altitude and lacking grid electricity, relied entirely on diesel for its irrigation needs.
The system combines solar photovoltaic (PV) arrays with diesel generators, providing power for the farm's irrigation systems. Solar power meets the majority of the energy demand during daylight hours, while the diesel generators automatically supplement when solar output is insufficient, particularly during summer months. This hybrid model effectively addresses the need for round-the-clock irrigation without full dependence on fossil fuels.
In its initial year of operation, the solar irrigation system achieved 223,400 kilowatt-hours of solar energy generation and saved 16,385 gallons of diesel, a 60% reduction in fuel requirement. While projections suggested potential savings of up to 75%, the initial start-up in late April 2019 limited its full contribution. The project received a grant of $253,405 through the Rural Energy for America Program, underscoring its economic and environmental benefits.
