Harmony House

Objectives & Site Considerations
Richard and his family wanted to build a house that was as sustainable as possible – relying on their own solar energy to run their home.
Using the Design for Place house plans from the YourHome website, they would make use of passive solar design (thermal mass, cross-ventilation and window placement) to reduce their energy requirements.

Load Analysis
Ave Summer Demand: 13.84kWh/day
Ave Winter Demand: 18.12kWh/day
Design Surge: 7.33kW

System Design
1 x Selectronic SP PRO SPMC482 Inverter Charger
24 x BAE VRLA Sealed Gel Batteries (76.8kWh)
48 x REC Solar 290W solar modules (13.92kW)
2 x Fronius Primo 6.0-1 solar inverters
Selectronic ‘Quick View’ monitoring with tablet display

Project Outcome
The winter energy production generously accommodates the household usage, and summer production far exceeds what is used. The battery bank has rarely been below 80%, and Richard has future plans to purchase an electric vehicle (EV) with at-home charging.
