Sunergise has activated New Zealand’s largest rooftop solar system, a 5.3 MW array at Fisher & Paykel Healthcare in Auckland. This project significantly boosts the country’s solar capacity and sets a new benchmark for commercial renewable energy adoption.
Sunergise has completed and commissioned the largest rooftop solar system in New Zealand, a 5.3 MW grid-connected array installed at Fisher & Paykel Healthcare’s Auckland campus. This milestone marks a significant expansion of the country’s commercial solar capacity and highlights growing corporate investment in renewable energy.
The 5.3 MW 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 is expected to generate over 6,600 megawatt-hours of clean energy annually, offsetting more than 486 tonnes of carbon dioxide each year.
The project was completed in nine months and was delivered under Sunergise’s SunPlus Power Purchase Agreement (PPA), allowing Fisher & Paykel Healthcare to pay only for the electricity produced without upfront capital costs. The installation is connected to the national grid and is the largest rooftop solar system currently operating in New Zealand.
Sunergise CEO Paul Makumbe described the project as a new standard for the country’s energy sector, emphasizing its role as a replicable model for large energy consumers seeking to reduce costs and carbon footprint. Fisher & Paykel Healthcare’s vice president of supply chain, Jonti Rhodes, stated that shifting to solar is a smart business move and hopes it encourages other companies to follow suit.
Implications of the Largest Rooftop Solar System in NZ
This development demonstrates the increasing viability and scale of commercial solar projects in New Zealand, signaling a shift towards cleaner energy sources among large businesses. It underscores the country’s commitment to expanding renewable capacity, which is vital for meeting climate targets and reducing reliance on fossil fuels.
The project also serves as a proof of concept for other companies considering solar investments, potentially accelerating the sector’s growth. As solar capacity is projected to triple by 2031, this installation exemplifies how corporate leadership can drive national renewable energy goals and influence market trends.

Growing Solar Capacity and Industry Trends in NZ
New Zealand’s solar sector has experienced rapid growth, with total installed capacity expected to reach over 860 MW by 2026. Industry research indicates that this capacity could increase to more than 2,100 MW by 2031, driven largely by commercial and industrial rooftop projects.
Previous record-holder for rooftop solar in New Zealand was a 2.3 MW system at Mānawa Bay shopping centre, also installed by Sunergise. The new 5.3 MW array at Fisher & Paykel Healthcare more than doubles that capacity, reflecting a significant leap in scale and technological adoption.
This growth is supported by falling costs of solar modules, supportive policies, and a broader corporate push towards sustainability and cost savings through renewable energy investments.
“This is a landmark project for New Zealand. A 5.3 MW system on the rooftop of one of the country’s most recognised companies shows what’s possible when businesses commit to clean energy at scale.”

Remaining Questions About the Project’s Long-Term Impact
It is not yet clear how this project will influence broader industry adoption or whether similar large-scale rooftop systems will be deployed across other sectors in New Zealand. The long-term operational performance and financial returns for Fisher & Paykel Healthcare remain to be evaluated.
Additionally, the potential for grid integration challenges or regulatory changes affecting such projects is still uncertain, as the sector continues to evolve.
