1KOMMA5° New South Wales: Solar, Battery Storage & AI Optimisation Experts

Been waiting 2 months for service of our enphase system still no response from them at all. No such thing as after sales service. If I could leave zero stars I would

I had a great experience with these guys when they were SolarRay. Since becoming 1K5 it seems like a shambles. I signed in September for a December install. Skipping many boring steps of them neveer rescheduling and never returning calls and emails, eventually a sales manager was in touch, i signed a new contract accepting some higher costs and awaited my booking appointment. That was 2-3 months ago. This is a clown show you want avoid. I'm leaving this review half to see if it will prompt anyone to return a call or email... Bring back the old SolarRay. Please.

I had solar installed by this Company (formerly Solaray) approx 15 years ago. I then upgraded to a new system about 3 years ago. 8 months ago I needed two of my panels moved so I could install a skylight. 1KOMMA5 obviously is not interested in helping in any regard after their initial install. I have been calling and emailing on a regular basis following up on promise after promise from this Company. Nobody will give me a direct phone number, nor call me. They simply put this task in a too hard basket and forget me. Its incredible. I want to cut and paste the email chain because anybody will find it laughable. Unfortunately this review will not allow it, but should you want to see how they deal with existing customers after they install and get their money, Im happy to forward every email message I have. Today they have promised to call me again. This is maybe the 25th promise ... lets see

Resolving customer issues is slow and frustrating for the customer. Our system has not been reporting to the enphase app since March 6th. After trying many times to reconnect to the internet it was decided that the equipment is faulty and needs replacing. Enphase apparently does not communicate with 1Komma5 who are installing the replacement from Enphase under warranty. I contacted them on 31/3/2026 to inform them that I have the replacement and requested an appointment date for installation. It is two weeks later and I have heard nothing. It appears that 1Komma5 are not invested in customer service.

Overall good experience, happy with the product

Unfortunately, whilst the lead up service was excellent, 4 months later and my service is not working. It took a month for the system to be switched on, then 4 months later I still haven’t got my energy provision working. So the battery isn’t filling even though I signed up for the cheap energy provision. I’ve contacted support, which appears to be one guy who has been so sick he can’t speak to me - for four weeks. I am completely perplexed and disappointed.

We got a battery installed with 1Komma5. The sales team (Cameron and Lisa) were very patient while we experimented with a range of configurations and prices, Daniel the installer and his team were very professional and did a really neat job (and helped move things around to get the right circuits on the automated backup), and when there was a fault Aaron was extremely helpful in getting the tech straight back out to get it resolved. Very happy with the app and the experience so far.

Stephen Catchpole

Outstanding service from the time of sign up to installation. The installation day itself ran smoothly and the professionalism and personal engagement of Trae and his partner left us assured we were in reliable and expert hands. A small pre-existing electrical problem was identified and rectified as soon as Trae became aware - our thanks to him and the 1KOMMA5 team. I would most certainly refer them positively to any interested future customer. Very excited about switching the system on and further engaging with the team to ensure maximum benefit!

1komma5 has been so helpful from helping me sizing the solar battery that fits my household needs, to finding the right installation location. The team like Jess from Sales, Maddie from scheduling were great. Daniel, the installer, was awesome. He came in early, performed installation even though it is not easy. He accommodated my concerns. He was so patient helping me setting up the backup power options, very knowledgable and provided me tips on how to make the most of my shiny new solar battery. 1komma5 made the experience so easy in jumping into complex world of green energy. I cannot recommend them enough.
