TL;DR
Sunergise has activated New Zealand’s largest rooftop solar installation, a 5.3 MW system at Fisher & Paykel Healthcare’s Auckland site. This project doubles the previous record and highlights rapid sector growth.
Sunergise has completed and officially commissioned New Zealand’s largest rooftop solar system, a 5.3 MW grid-connected array installed at Fisher & Paykel Healthcare’s Auckland campus. The project marks a significant milestone in the country’s renewable energy sector and demonstrates the potential for large-scale commercial solar adoption.
The solar installation spans approximately 70,000 square meters across two buildings on Fisher & Paykel Healthcare’s site in Auckland. It features 8,273 solar modules and was built over nine months. The project was delivered under Sunergise’s SunPlus Power Purchase Agreement (PPA), allowing Fisher & Paykel Healthcare to pay only for the electricity generated, with no upfront capital costs.
Once operational, the system is expected to produce more than 6,600 megawatt-hours (MWh) of clean energy annually, offsetting over 486 tonnes of carbon dioxide each year. This installation surpasses the previous largest rooftop system in New Zealand, which was a 2.3 MW array at Auckland Airport’s Mānawa Bay shopping centre.
Setting a New Standard for Commercial Solar in NZ
This project exemplifies the rapid growth of solar capacity in New Zealand and sets a new benchmark for large-scale rooftop installations. It demonstrates the feasibility and benefits of deploying extensive solar arrays on commercial sites, encouraging other businesses to consider renewable energy investments. The project also aligns with national goals to increase renewable energy use and reduce carbon emissions, potentially influencing policy and industry standards.

Rapid Growth and Industry Momentum in NZ Solar Sector
New Zealand’s solar sector has experienced significant expansion, with industry estimates projecting installed capacity will triple from 860 MW in 2026 to over 2,100 MW by 2031. This growth is driven by increasing commercial and industrial adoption, as companies seek to lower energy costs and meet sustainability commitments. The Fisher & Paykel project reflects broader trends of large-scale renewable deployment and the shift toward cleaner energy sources in the country.
“This project sets a new standard for what’s achievable in New Zealand’s energy landscape and offers a scalable model for other large energy consumers.”

Remaining Questions About Project Impact and Replicability
It remains unclear how many other large-scale commercial sites in New Zealand will follow suit, and whether the project’s success can be broadly replicated across different industries and regions. Additionally, data on the long-term financial and operational performance of this specific installation is not yet available.
Next Steps for Large-Scale Solar Adoption in NZ
Expect further announcements of similar projects as the sector accelerates. Policymakers and industry stakeholders will likely monitor this project’s performance and economic impact, shaping future incentives and regulations to support expanded renewable deployment. Ongoing evaluation of the system’s energy output and cost savings will inform future investments.
