TL;DR
Sunergise has activated New Zealand’s largest rooftop solar installation, a 5.3 MW system at Fisher & Paykel Healthcare’s Auckland campus. This project marks a significant milestone in the country’s renewable energy growth.
Sunergise has activated the largest rooftop solar system in New Zealand, a 5.3 MW grid-connected array installed at Fisher & Paykel Healthcare’s Auckland campus. This development marks a significant milestone in the country’s renewable energy sector, demonstrating the scale of commercial solar adoption and setting a new industry standard.
The 5.3 MW solar installation spans approximately 70,000 square meters across two buildings at Fisher & Paykel Healthcare’s Auckland site. It features 8,273 solar modules and is expected to generate over 6,600 MWh of clean energy annually, offsetting more than 486 tonnes of carbon dioxide each year. The project was completed in nine months and was financed through SunPlus Power Purchase Agreement (PPA), allowing Fisher & Paykel to pay only for the energy produced without upfront costs.
This project surpasses the previous largest rooftop array in New Zealand, which was a 2.3 MW system at Auckland Airport’s Mānawa Bay shopping centre. Sunergise CEO Paul Makumbe described the project as a new standard for the country, illustrating what is possible when large-scale businesses commit to renewable energy. Fisher & Paykel’s vice president of supply chain, Jonti Rhodes, emphasized that shifting to solar power has already proven to be a smart business decision, aligning environmental goals with cost savings.
Impact on New Zealand’s Renewable Energy Goals
This project demonstrates the increasing viability and scale of commercial solar in New Zealand, encouraging other large businesses to adopt renewable energy solutions. It supports the country’s broader goal to expand renewable capacity, which industry estimates suggest will triple from 860 MW in 2026 to over 2,100 MW by 2031. The project also highlights the role of innovative financing models like PPAs in accelerating renewable adoption without requiring significant upfront capital.

Growth of Solar in New Zealand’s Business Sector
New Zealand’s solar sector has experienced rapid growth, with installations expanding significantly in recent years. Prior to this project, the largest rooftop array was 2.3 MW, installed at Auckland Airport. Industry forecasts indicate a tripling of solar capacity over the next five years, driven by declining costs, government incentives, and corporate sustainability commitments. The Fisher & Paykel project exemplifies this trend, showcasing how large industrial players are integrating solar into their energy mix.
“This project sets a new benchmark for large-scale solar in New Zealand and could serve as a model for other corporations seeking to reduce their carbon footprint.”
