What customers say

Based on genuine customer reviews

In Bankstown and across Sydney, Ultimate Energy Australia has earned repeat praise from homeowners upgrading to solar and battery storage. Customers in several reviews describe the process as straightforward and professionally managed from start to finish. More than one review highlights clear communication before, during and after installation, singling out Genevieve for proactive follow-ups and meticulous attention to detail, and Nasir Kamal for guiding buyers towards suitable systems.

Install crews come in for similar credit, noted for working efficiently, leaving sites clean and completing jobs promptly. A detail many reviews return to is the willingness to explain each stage in plain terms, so households understand what is being installed and why.

Customers who compared quotes describe fair pricing, quick lead times and a broad selection of quality products, including 7.9kW and 10.4kW solar setups paired with battery storage such as the Anker Solix x1. Systems are often running within hours of completion, and after-sales support draws consistent thanks, from small contract adjustments to follow-up advice.

The detailed care pack handed over on completion is likewise appreciated, rounding out a profile built on thorough advice, smooth installation and attentive service.

Recently upgraded from my old panels to a 10.4kW solar and 42kWh battery package through Ultimate Energy Australia, and I couldn't be happier with the result. A special mention to Genevieve — her communication was exceptional throughout. She was proactive with follow-ups and kept me informed of any changes to the quote, which made the whole process stress-free. The install team were just as efficient and communicative, got the job done smoothly. Couldn't ask for better service honestly, all round. Highly recommend Ultimate Energy Australia if you're considering an upgrade.

BATTERY & SOLAR INSTALL “The ultimate experience from quote to installation! The quoting process was simple, and even when I made a few changes along the way, they accommodated everything with ease. Genevieve was absolutely fantastic to deal with – no pressure, just genuine service. The installation team did an excellent job and I couldn’t be happier with the result.”

I researched solar and battery extensively. I finally settled on Ultimate Energy’s deal based on quality of product, lead time, and of course price. They won out on all fronts. Great deal, and I’m stoked with the quality and the team who installed it!
