Mike Saves $3,800 a Year with a 10.92kW Solar and Battery System
The Challenge
Mike, a homeowner in Woongarrah on the Central Coast, was tired of rising electricity bills eating into his household budget. Month after month, he felt powerless against whatever charges his retailer imposed. Most of his family’s energy use happened in the evenings, so solar alone wasn’t enough. He needed a solution that worked day and night.
The Motivation
For Mike, it wasn’t just about lower bills it was about taking back control. He wanted energy independence, long-term financial predictability, and freedom from the stress of constant bill hikes. After years of watching battery tech improve, he was waiting for the right moment to make the investment.
The Solution
Wattle Powr designed and installed a 10.92 kW solar + Tesla Powerwall 3 battery system, optimised for his family home. By pairing high-output solar with a powerful battery, Mike could use his own clean energy around the clock, not just during daylight hours. With flexible finance through CommBank, the decision was simple.

The Outcome
Since installation, Mike hasn’t just cut his bills—he hasn’t paid one. His solar and battery combination consistently generates more power than his family consumes, keeping his account in credit for six straight months. Now, his home is future-ready, resilient, and financially stable.

“I haven’t paid a bill since the first one, which was only $13. Since then, I’ve been in credit every month. With solar and a Tesla Powerwall, I finally feel empowered, like I’m in control of my home’s energy future.”
