New Zealand commercial solar company Sunergise has switched on the country’s largest-yet rooftop solar system, commissioning a 5.3 MWp array installed at an industrial site in Auckland.
Sunergise has completed the largest rooftop solar system currently operating in New Zealand, officially switched on a 5.3 MW grid-connected PV system mounted across Fisher & Paykel Healthcare’s administration and manufacturing campus in Auckland.
Spanning approximately 70,000 m2 across two buildings and featuring 8,273 solar modules, the system is more than twice the size of the country’s previous largest rooftop array, the 2.3 MW array installed by Sunergise at Mānawa Bay shopping centre at Auckland Airport.
The Fisher & Paykel project took nine months to build and was delivered under Sunergise’s SunPlus Power Purchase Agreement (PPA), meaning Fisher & Paykel Healthcare pays only for the electricity generated, with no upfront capital cost.
The completion of the project comes with New Zealand’s solar sector growing rapidly. Industry research suggests installed solar capacity will triple from 860 MW in 2026 to more than 2,100 MW by 2031, with commercial and industrial rooftop adoption accelerating as businesses seek to reduce electricity costs and meet sustainability targets.
