EECA (the Energy Efficiency and Conservation Authority) is calling on farmers and growers to take part in a new programme that will show how solar and battery systems can cut energy costs and build resilience on New Zealand farms.
The initiative will support farmers to install solar and battery systems, monitor performance, and share practical insights — particularly around battery use — with the wider farming community.
“Farmers are looking for reliable ways to manage rising energy costs and improve resilience,” said Megan Hurnard, EECA GM Insights, Data and Communication.
“By showcasing real-world results across different farming systems, this programme will give the sector confidence about what solar and battery technology can deliver.
EECA’s early modelling indicates that if 30 per cent of Kiwi farms installed larger systems — of the size we see on some farms already — they could generate as much as 10 per cent of New Zealand’s current electricity demand.
“We are looking for a broad range of different farm types — dairy, sheep and beef, horticulture, and poultry - and a spread of locations across New Zealand. If you are keen to get involved, we would love to hear from you,” said Hurnard.
Applications for the demonstration open 18 September 2025 — more detailed criteria will also be made available on this date. Farmers and growers keen to take part can apply through EECA’s website. Systems must be installed by 30 June 2026.
By farmers, for farmers
Participating farmers will play a leading role in proving how the technology performs day-to-day. The programme aims to answer key sector questions:
- How well do solar and battery systems perform on different farm types?
- Are they practical, cost-effective, and resilient enough to support farm businesses?
- What benchmarks, tips, and tools can be shared with other farmers?
Results and data will be collected over five years to provide robust evidence and guidance.
What’s involved
- Funding support: Up to 40% for inverters and batteries, and up to 20% for solar panels (capped at $200,000 per farm).
- Demonstration sites: Farms will become case studies to shape best-practice advice for the whole sector.
- Sector-wide impact: Practical, farmer-led insights will be shared widely.
A new solar helpline
EECA has set up a new, dedicated helpline to help farmers understand if solar is right for farm and what the potential return might be, get neutral advice to compare quotes, help work through any issues around consenting.
Farmers can call 0800 300 643 to speak directly with Chris and the team at EECA, about the broader programme, funding, and application process. “We also want to hear about any barriers or challenges being faced along the way,” said Hurnard.
This funding is part of a broader Solar on Farms programme that EECA is developing in collaboration with farmers, sector bodies, and technical experts.
“We think there is a lot of potential for powering activities like irrigation, harvesting technology, and heating and cooling systems through solar systems,” said Hurnard.
“Maintaining the connection to the grid gives the farmer the ability to sell excess generation back to the grid to support the network and contribute to New Zealand’s electricity system.
“By adopting this innovative technology, you’ll not only strengthen your own business, but help shape the future of energy on farms across New Zealand.”

Tips for farmers and growers considering solar
- Plan for growth — Electrification increases demand.
- Size your system for peak operations — Consider including panels for frost fighting, charging, and vehicle use.
- Batteries help, but grid support is still valuable — The grid gives you flexibility and resilience but most of your power can still come from your own panels.
- Start with irrigation — It's the easiest and most impactful load to electrify using solar directly.
- Efficient electric equipment is now on the market — Tractors, mowers, and carts are all commercially available now.
