Solar Hub designed the perfect system for this Taupo home to help them slash their bills and get the best return on investment!
Location: Acacia Bay, Taupō
Industry: Residential
Installer: Solar Hub NZ Limited
System Installed: 12.29 kW Solar + 15.6 kWh Battery Storage
This modern home in Acacia Bay, Taupō, made the switch to solar to reduce rising electricity bills and gain long-term energy independence. With annual power usage of around 12,551 kWh, the homeowner wanted a system that could fully offset their electricity consumption while taking advantage of Taupō’s excellent solar conditions.
Solar Hub NZ designed a high-performance solar and battery system capable of generating more energy than the household uses over a full year.
The Challenge: Designing Solar for a Multi-Roof Home
The property features a complex roof layout with multiple gables and a mix of east- and west-facing roof sections. This meant the solar design needed to:
- Capture sunlight from early morning through late afternoon

- Stay within the local 5 kW grid export limit
