TL;DR
Sunergise has activated New Zealand’s largest rooftop solar installation, a 5.3 MW system at Fisher & Paykel Healthcare in Auckland. The project highlights rapid sector growth and business sustainability efforts.
Sunergise has completed and officially commissioned New Zealand’s largest rooftop solar system, a 5.3 MW 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 increasing adoption of large-scale solar by commercial entities.
The 5.3 MW grid-connected photovoltaic system covers approximately 70,000 square meters across two buildings at Fisher & Paykel Healthcare’s Auckland site. It features 8,273 solar modules and took nine months to install. The project was delivered under Sunergise’s SunPlus Power Purchase Agreement (PPA), enabling Fisher & Paykel to pay only for the electricity generated, with no upfront capital costs.
The system is projected to generate over 6,600 megawatt-hours (MWh) annually and offset more than 486 tonnes of carbon dioxide emissions each year. This installation surpasses the previous largest rooftop array in New Zealand, which was 2.3 MW at Mānawa Bay shopping centre at Auckland Airport.
Sunergise CEO Paul Makumbe described the project as a new standard for New Zealand’s energy sector and a model for large energy consumers seeking to reduce costs and emissions. Fisher & Paykel’s vice president of supply chain, facilities, and sustainability, Jonti Rhodes, emphasized that shifting to solar is both environmentally responsible and a strategic business decision.
Implications for New Zealand’s Renewable Energy Sector
This project underscores the rapid growth of solar capacity in New Zealand, which industry research suggests will triple from 860 MW in 2026 to over 2,100 MW by 2031. It demonstrates that large-scale rooftop solar is becoming a viable and attractive option for commercial and industrial sectors, driven by cost savings and sustainability goals. The project also sets a precedent for other businesses considering similar investments, potentially accelerating the country’s transition to renewable energy.

Background on New Zealand’s Solar Expansion
New Zealand’s solar sector has experienced significant growth in recent years, with cumulative installed capacity reaching approximately 860 MW by 2026. The trend is driven by decreasing costs, policy support, and an increasing focus on corporate sustainability commitments. The Fisher & Paykel project, completed in nine months, is part of a broader shift where large companies are adopting solar to meet environmental targets and reduce reliance on grid electricity.
“This installation sets a new benchmark for what’s achievable in New Zealand’s commercial solar market.”
