Fully off‑grid energy system for a winery and restaurant operation
Huntington Estate Winery
Solar-powered pumping with a three-year payback
Client

Project
Off-Grid Solar + Diesel Hybrid Water Pumping
Location
Mudgee, NSW
Background
Huntington Estate Winery needed a cost-effective, reliable way to move water from an existing bore to support their operations. Traditional pumping methods weren’t delivering the efficiency needed, and power costs were steadily rising. They turned to SPS Solar + Water for a better solution.
The Solution
SPS designed and installed an 11.16kW ground-mount solar array, paired with a 5.5kW submersible pump (variable speed drive). During peak summer, the system supports 10 hours of solar run time, including 6 hours of full-speed pumping, delivering between 120,000L and 150,000L of water per day using solar alone. A diesel generator kicks in when needed, particularly during winter when solar hours drop.
Impressed with the performance and savings, Huntington Estate commissioned a second project, an 87kW grid-connected solar system to power their processing plant, offices, and cellar door.
“It was a very simple process and it’s led us to look at solar for all of our other operations… Solar is a no-brainer really. It’s taken me 10 years to get to this point and I’m just kicking myself I didn’t get here earlier — pretty stupid really…”
Key Result
A three-year payback and ongoing savings of ~$10,000 annually, with solar systems now powering both their water supply and production operations.
