Skyrocketing commercial electricity prices are now one of the most powerful reasons New Zealand farmers and agribusinesses are turning to solar. In 2025, commercial electricity charges rose by an average of 22%, putting significant pressure on rural operating costs and highlighting the need for long-term energy solutions that protect the bottom line.
With banks now offering dedicated commercial solar loans and the government's new 20% "Investment Boost" tax deduction, 2025 presents the strongest financial case yet for farm solar power systems NZ. Early-stage adoption is picking up as farmers look to lock in energy price certainty, secure cost savings, and strengthen their resilience against future price shocks.
Solar Adoption in Rural NZ: Just Getting Started
Solar uptake in New Zealand is at an early stage, though growth is picking up pace. As of May 2025, solar energy makes up approximately 1.4% of all electricity generated in the county, with rural and agricultural installations still representing a small but rapidly growing share of the total. In the past 12 months, 32% of all NZ's grid-connected solar capacity was installed - a clear sign that more landowners are now considering the benefits.
Leading Banks: Commercial Solar Loans for Rural Business
To remove the up-front barrier for solar panels or solar power systems NZ, banks now offer targeted finance for rural and agri-businesses:
| Bank | Max Loan Amount | Rate/Term | Usage |
| ASB | $150,000 | 0% 5 years, interest-free | Farms & rural businesses; solar+batteries |
| BNZ | $80,000 | 1%, 3 years | Farm/business green initiatives (solar, BESS) |
| Westpac | $50,000 | 0%, 5 years interest free | Solar and battery installs for businesses |
| ANZ | $80,000 | 1%, 3 years | Agri/Commercial customers for energy upgrades |
| Kiwibank | $2,000 | Grant | Contributes to business/farm solar investments |
These products are only available to commercial and agricultural customers, not residential accounts.
The 20% "Investment Boost": Immediate Tax Relief for Farm Solar
The government's new "Investment Boost" policy allows businesses, including farms, agribusiness and rural enterprises, to immediately deduct 20% of the solar installation cost from taxable income. Here's how it works for solar panels NZ cost:
- You invest $100,000 in a solar power system
- $20,000 of that is an up-front tax deduction in year one.
- The remaining $80,000 is depreciated over the usual asset lifetime.
This move means immediate cashflow relief, faster payback, and a stronger business case for solar in any agricultural setting.
