Case study: 56-panel solar hot water system for 8 Willis St, Wellington

In 2022 we completed the installation and commissioning of a 56-panel solar thermodynamic hot water system for the redeveloped Stats NZ and Ministry for the Environment building at 8 Willis Street, Wellington.

The system

The installation is made up of two independent 28-panel Energie systems, each with 4,000L of storage, giving 8,000L in total. It supplies hot water to toilets, kitchens and end-of-trip facilities for up to 1,200 staff. Our client, McKee Fehl, chose this technology because it fitted the project's sustainability and energy efficiency goals.

What the client says

"We engaged TAEC to design, supply and install a solar energy hot water solution for Stats NZ and MFE offices at 8 Willis St, Wellington. The system had to cater for up to 1200 government tenants, supplying hot water to toilets, kitchens and end-of-trip facilities, with an 8000L storage capacity.

We were very happy with TAEC's collaborative approach in providing this system and it is performing as designed. I certainly recommend that universities, hospitals, hotels and large government institutions consider this type of system for supplying their hot water needs, reducing their costs, and reducing their carbon emissions."
