As power prices continue to rise across New Zealand, dairy farmers are feeling the squeeze more than most. With irrigation systems, milking sheds, and other on-farm tech relying heavily on electricity, energy costs are becoming a major pain point. But ASB has launched a game-changing initiative: the ASB SMART Solar Loan – a powerful new offer that helps rural businesses invest in solar energy with zero-interest finance.
What’s on Offer?
ASB is now offering interest-free loans of up to $150,000 for five years to eligible rural customers investing in solar and battery systems. That means farmers can get started with clean, self-generated energy without the burden of high upfront costs — the #1 reason many haven’t made the switch to solar.
This offer is designed to:
- Reduce power bills significantly over time.
- Improve energy resilience for rural operations.
- Help cut carbon emissions and future-proof the farm.
Tools to Help You Plan Smarter
To help farmers understand the full value of switching to solar, ASB has partnered with Prism Earth to create a suite of interactive online tools. These digital tools will be available soon and will allow dairy farmers to:
- Map optimal solar locations on their farm.
- Calculate potential energy savings and emissions reductions.
- Estimate payback time based on real farm data.
Early modelling shows that a typical 250m² ground-mounted solar system could save up to $598,200 over its lifespan, with a median installation cost of around $110,600. Many farms could see a full return on investment by year six of operation.
Why It Matters for Dairy Farmers
For dairy operations, energy use is both critical and constant — from running refrigeration and vacuum pumps to powering irrigation during dry spells. And with rural properties often last to be reconnected after outages, energy independence is no longer a luxury — it’s a necessity.
North Otago dairy farmer Otto Dogterom installed a 240kWh solar system in 2021 to power irrigation on his 300-hectare farm. His motivation? Rising power prices and a desire to gain more control over his operating costs. “Power prices were going up faster than inflation,” he says. “It just made sense to future-proof.”
Otto’s setup is an example of how solar energy doesn’t just make environmental sense — it makes strong business sense.
