SigEnergy 3 Phase 15kWh Solar Array with a 24kWh Battery System and EV Charger
“When we first looked at a solar option for our recently completed build we found out our setup would be more difficult than a standard installation. While other solar installation companies were pushing the hard sell at the time, we found the team at Ecoefficient upfront and honest about the potential issues and technology required to get the best out of a solar install. 1 year later when we revisited the obstacles with Shaun and the team, the technology had progressed, and they provided a solution which was best for us as the clients. The install, and post-install service has been great!”

When Ed approached us, his vision was simple maximize: his transformer capacity with as many panels as possible. The result? A solar farm on his farm, creating a second income stream while powering a cleaner future. With a 15% ROI, it’s not just sustainable for the planet, it’s sustainable for his business too – a truly bright idea.

“We had an excellent experience with Ecoefficient installing our off-grid solar system. From the initial consultation, Shaun and his team took the time to understand our energy needs and provided clear, practical advice on system design, sizing, and performance expectations. The installation was smooth and well-organised, with high-quality workmanship and attention to detail throughout.
We couldn’t be happier with the outcome and would highly recommend Ecoefficient to anyone considering solar, especially off-grid solutions. They deliver both technical excellence and peace of mind.”
