What customers say

Based on genuine customer reviews

The personal involvement of owner Jack Greenfield emerges as a recurring theme, with reviewers describing his advice and responsiveness in consistently positive terms. He is said to visit properties to assess needs, explain inverter and battery options in plain language, and offer competitive quotes that several customers report as better value than others they had received. Installation standards attract similar praise: Adam is named for a swift, tidy job and for discussing panel layout and inverter placement, while Harley and his offsider are credited for their workmanship. Kyle is singled out for a thorough clean and service that noticeably improved system output.

Clients also describe a smooth journey from first enquiry through to completion, including efficient handling of battery rebate paperwork and continuing after-sales monitoring years after the original installation. Off-grid and larger hybrid setups with phone-linked monitoring appear in accounts, as do residential and commercial projects where the same care is reported for each client. Cairns customers appreciate that the team is local, communicates well before and after the job, arrives when agreed and leaves the site tidy. Speed is a further point that comes up often, with one system installed within days of the initial contact.

Jack is a fair-weather salesman, very attentive when winning your business, but once things get even slightly complicated, expect ongoing delays and excuses. The physical install itself was fine, but it took months for the system to actually become operable. We’ve since had the inverter fail (thankfully repaired under warranty), but the whole process has been unnecessarily drawn out and stressful. Overall, not a smooth experience.

Our second time having solar installed by Greenfield Energy and I am sooooo happy. We have a huge system, a fancy inverter that hooks up to our phone and we can see exactly what we are producing vs using and soon, a big battery system too. Office staff and operation staff are on point. Very happy. Highly recommend!

100% would recommend, the owner Jack is a expert and gave us so much better value for money compared with other quotes we received . He took the time to educate us on the perfect system for our home and explained thing property so we easily understood all the new inverters and battery systems on the market. We are now enjoying no electricity bill since the install and we can run our A/C without the fear of a big bill from Ergon!

We recently had our solar panels cleaned and serviced by Greenfield Energy, and we couldn't be happier. ​Kyle was professional and incredibly thorough. Our system's performance has noticeably improved since the service, and he made the whole process very easy. ​Highly recommend for anyone needing a solar maintenance or solar cleaning.
