Ben Saves $4,000 a Year with a 8.19kW Solar and Battery System
The Challenge
Ben had just finished building his new home in East Corrimal, NSW. With a young family to support and rising energy bills, he wanted to future-proof the property from day one. His goal was clear: design a home that combined comfort with energy independence.
The Motivation
As a new homeowner, Ben wanted to avoid the trap of high, unpredictable energy bills. He saw solar as a smart, future-proof investment that would give his family financial stability and energy independence. Trust and quality workmanship were his top priorities. He didn’t want shortcuts taken on his brand-new home.
The Solution
We designed a tailored 8.19 kW solar + battery system, optimised exactly as Ben requested, with panels installed on the northern roof to capture maximum solar exposure. Because Google Maps hadn’t yet updated his address, our team carried out a site inspection to design the system with precision and ensure flawless integration with his new build.

Happy Customer
“I recently had Wattle Powr install a solar system at my home, and the experience was excellent from start to finish. Their team was professional, knowledgeable, and transparent throughout the process. Installation was smooth and efficient. The crew arrived on time, worked neatly, and ongoing communication was great. I’d highly recommend them to anyone considering solar. Especially if you want a hassle-free experience with great results.”
