About
Greenultimate Pty Ltd has been designing, engineering and installing solar PV systems since 2010.
We are a Clean Energy Council accredited member, providing residential, commercial and government solar and battery solutions across NSW, ACT,NT, WA and SA. Since inception, Greenultimate has completed over 50MW of installed solar capacity, generating more than 20 million kWh of clean energy for our customers. Our project portfolio spans homes, schools, aged care facilities, hotels, motels, farms, retailers and major public infrastructure — including the solar installation at Sydney Olympic Park's Genea Netball Centre.
We employ over 50 staff and contractors across our Services and Projects business units, with local offices and representatives in metro and regional areas including Blacktown, Macquarie Park, Darwin, Canberra, Adelaide, Perth, Moree and Broken Hill — allowing us to service both major cities and remote/outback communities that many providers overlook.
Our work is underpinned by five core values: Safety, Honesty, Integrity, Transparency and Innovation.
We don't just install systems — we manage, maintain, service, replace and repair them long-term, with many customers returning to us for repeat installations, upgrades and battery add-ons across a decade or more. We install and support leading brands including Trina, LONGi, Canadian Solar, Jinko and Aiko Panels; Fronius, Goodwe, SMA, K-Star, Sigenergy, Huawei, Fox ESS and Alpha-ESS inverters and battery storage systems.
Reviewers report paying: $10,500 - $13,000 for depending on hardware choice and installation difficulty ( how is this calculated? )

Dealing with Greenultimate for over 8 Years
Greenultimate did my solar way back in 2012.Over the years I moved places and everytime I moved into place I have contacted them.
Their sales team have always guided me properly and suggested the right system.
Never over promised anything and have been honest and upfront.
They have kept me updated with new rebates and recently about NSW HESLP.
Thanks Warnie & Team

Fantastic installer and a job well done.
We got our 48 kwh Fox ESS battery installed just before 1 May 2026. Hashim is great in explaining different options available to us just two weeks before 1 May 2026. He is very responsive to our queries and very effective in organising the installation on time. The installer did an excellent job as shown in the picture. The system has been running smoothly, happy monitoring via the app.Inverter rating: 5/5

Greenultimate has always looked after my bills. I have multiple properties and they have done solar and batteries for me and my family from 2010-2026.They have always looked after us and every time their systems did better than what was promised. Tim & Junaid are their local representatives in far west NSW region. Great dealing with them.

Stay clear of Green Ultimate
I had a relatively painless experience through the sales and installation process. However, when the system didn’t appear to be working and they failed to initiate my app so I couldn’t check, my pain began. To describe Green Ultimate’s customer service as appalling would be an understatement. I called the office 6 times over a two month period and each time the office assured me that someone would contact me to work through the problem, I never received a call back. I also sent them two emails seeking assistance in fixing the system, I didn’t receive a reply to either email.The problem is fixed now, however,I greatly regret engaging the services of Green Ultimate and write this review as a cautionary tale - don’t go anywhere near Green Ultimate!

Stay away - power bill over tripled
Walli at Greenultimate Broken Hill was extremely friendly when selling the product, we have had both battery and solar for over 6 months, neither have worked,. Walli never comes through, I have spoken to fair trading and will be in touch again this coming week. High alert - won't respond. Greenultimate if I could give less than 1 I would.Panel rating: 1/5

All good solar system
Got a quote for a 6.6 solar system approx 6 years ago. Friendly people, good quote. Got system installed - it's been going good for 6 years and has not missed a beat. Rang them about a solar battery installation, very helpful, set up payment plan.System was installed 4 weeks ago, very professional installers, friendly and helped me set up app.system - it's going great no problems and will use them again for any solar systems.
