Solar & battery in Cardinia Lakes.
Cardinia Lakes is an established estate of large, mostly north-facing roofs with strong owner-occupier solar uptake. Two markets in one suburb — homes going solar for the first time, and the big base of existing arrays now adding batteries while the 2026 rebate is high.
The Cardinia Lakes solar story.
Large north-facing roofs, made for solar.
Cardinia Lakes homes sit on generous blocks with large, mostly north-facing roofs — the best orientation for a productive array. That makes a real 10kW solar system straightforward rather than a squeeze. After STCs a 10kW install runs about $8,500–$11,000 and pays back in roughly 4–5 years on a typical $350-plus quarterly bill. Where export to United Energy is limited, we size a battery so you keep your daytime solar rather than give it away.
Battery retrofits are half the work here.
A decade of estate ownership means Cardinia Lakes has one of the largest existing solar bases in the corridor — and most of those homes export their daytime surplus for a few cents. Adding battery storage flips that: store the surplus, run the evening peak on it, and lift self-consumption from around 30 percent to 70–80 percent. The 2026 Cheaper Home Batteries rebate takes roughly $252 per usable kWh off, so a 10kWh battery nets about $8,500.
