Home Solutions, partnering with Sunergise, delivered the largest rooftop solar system currently operating in New Zealand with the completion of Fisher & Paykel Healthcare’s Auckland campus.
As New Zealand businesses face rising energy costs, increasing grid volatility, and growing pressure to invest in resilient infrastructure, large-scale rooftop solar is emerging as a critical part of the solution.
A commercial project defined by scale
Located in Auckland, the solar system spans the Daniell and Paykel Buildings on Fisher & Paykel Healthcare’s hybrid campus in East Tāmaki. Each building measures approximately 35,000 square metres – a combined area approximately the size of seven rugby fields.
The system has been designed to capture as much on‑site generation as possible, resulting in a total installed capacity of 5.3 MWp and generating more than 6,500 MWh of clean energy annually.
In practical terms, this equates to around 8,300 high-efficiency 640-watt solar panels deployed across two expansive rooftops – enough to power over 800 average Kiwi households.*
The system has been sized to offset a significant portion of the site’s daytime energy demand, while also allowing flexibility for future expansion.
Designing for an occupied workplace
Unlike many large solar projects, this installation was delivered on a fully operational site. The buildings continued to function normally throughout construction, a constraint that introduced logistical and engineering complexities at every stage.
Materials arrived on site in 23 forty-foot shipping containers, requiring careful coordination for storage, access and movement. Weather windows, site access limitations and weekend-only crane lifts all had to be carefully managed to avoid disrupting Healthcare’s operations.
This type of delivery demanded more than technical capability; it requires experienced project management, deep construction knowledge, and the ability to coordinate across multiple partners in real time.
A new benchmark for New Zealand businesses
Beyond Fisher & Paykel Healthcare, the significance of this project lies in what it demonstrates for other organisations across New Zealand.
Large‑scale rooftop solar offers three compelling advantages for commercial and industrial sites:
-
Energy cost certainty
By generating electricity on site, businesses can significantly reduce exposure to wholesale price volatility and long‑term energy inflation. -
Smarter use of existing assets
Rooftop solar leverages under‑utilised roof space without competing for land, planning approvals or future development opportunities. -
Future-ready infrastructure
Systems of this scale can be extended over time, integrated with batteries, or adapted as site energy requirements change, supporting long‑term resilience.
For many businesses, the challenge has not been the technology itself, but finding a partner capable of delivering complex projects at scale. This installation shows what is possible when that capability exists.
Delivering at scale with Fisher & Paykel Home Solutions
The project was jointly delivered by Sunergise EPC, Sunergise Asset Co, and Fisher & Paykel Home Solutions, providing a fully integrated solution that includes engineering, procurement, construction, and a Power Purchase Agreement (PPA).
Together with global suppliers including JA Solar, Clenergy, and SMA, the teams delivered a technically complex system on time and on budget.
It also reflects a broader evolution for the business, from a heritage of product innovation to an integrated solutions provider capable of delivering complex energy infrastructure, at scale, across residential and commercial sectors.
