Installed in Harrisdale- 6112

A recent installation in Harrisdale demonstrates how a well-balanced solar and battery system can deliver strong performance without oversizing the solar array.

This home now operates with a 7.125 kW solar system paired with a 5 kW inverter and a substantial 40 kWh battery storage system. The design focuses on maximising usable solar energy and significantly reducing grid reliance.

Two tall white battery units with control panels, part of a 40 kWh battery storage system, are installed against a brick wall indoors, with pipes and electrical boxes above and between them. Two white safety bollards stand in front, and a closed door is visible on the right.

Solar panels with a 7.125 kW solar system are mounted on a brown tiled house roof under a blue sky, with neighbouring houses in the background. The panels are angled efficiently, and an inverter is installed for optimal energy use.

During the day, the 7.125 kW solar array generates clean energy to power the home while simultaneously charging the battery. Instead of exporting excess production at lower feed-in rates, surplus energy is stored on-site and used during the evening and overnight periods.

The 40 kWh battery capacity provides considerable energy reserves, allowing the household to:

Run evening appliances and lighting on stored solar
Offset peak tariff pricing
Maintain stable energy access during periods of low generation
Improve overall return on investment from their solar system

Solar panels installed on the tiled roof of a residential house, paired with 7.125 kW solar and a 5kW inverter, capture sunlight for energy generation. Nearby rooftops and a satellite dish are visible in the background.

Two rows of solar panels, part of a 7.125 kW solar system, are installed on the tiled roof of a house in a suburban neighbourhood. Other houses with similar roofs and some with solar panels can be seen in the background.

By matching the battery size to the home’s usage profile, this system offers flexibility and resilience. It ensures that the homeowner is less exposed to electricity price increases and better prepared for growing energy demand in the future.

This Harrisdale installation highlights how battery storage is becoming a central component of modern solar systems across Western Australia.
