Professional company excellence!

After the signing of the contract we were constantly updated on a regular basis by Jake White on the progress of our order and install dates which, due to weather conditions, changed a few times. When the installers arrived (After notifying of an arrival time 😀) they went through the install procedure and kept us up to date throughout the install of the solar panels and battery. They were very professional and polite throughout. We were very happy with the company and I would recommend 1Komma5 to anyone.

The very tidy installation of our new 1KOMMA5° solar battery

The very tidy installation of our 1KOMMA5° solar battery system went extremely well with an explanation of how the system works and the use of the PvHub app provided afterwards. A follow up phone call from Jake the next day provided confidence of team support going forward and he addressed any questions or concerns that we had.

Great overall experience

The overall experience I would say was pretty good. It took about 3 months to get installed. When they got close to date they notice they wouldn't have the required stock to fulfill my order so they upgraded my panels free of charge.

When the date came around for install no one showed up and the guy was sick this is completely understandable. However it was a little bit annoying it couldn't just get pushed to the following day but it had to get pushed another two weeks. Which resulted in me having to update my approval on the finance.

Other than that everything was an absolute fantastic experience the product is really good including the software. The software is very simple and easy to manage. You can tell it's very good quality.

I'm very happy with my purchase.

A brilliantly helpful company

The process of working out the best system for my needs was super smooth and 1Komma5 even helped out by pointing me to finance options. The sales team were knowledgeable and clearly excited by their own product without being pushy. When it came time to install everything was very fast and professional and the installers explained how it all worked and what all the pieces are. After that they had recommendations for energy providers who better optimise for batteries than my old one does. I appreciate the way 1Komma5 think big picture about they whole process and not just their little piece of the puzzle. I really couldn't be happier.

Great communication throughout my home battery installation process. From my initial quote inquiry to the comissioning of the system and the follow up to make sure everything was ok, I felt that I was in good hands.

I'm quite impressed so far. The process was fast and hassle free. The battery works fine and I'm waiting to try the Amber subscription too which will hopefully make even more money for us.

Excellent Product, Service and Team

The whole experience buying solar from 1Komma5 has been outstanding. From Martin, Rep, to Brady and the boys, Installation and Jake, Booking Coordinator, all have been courteous, informative and a pleasure to talk with. Early days yet, but the Solar Panels are doing a fantastic job. Great to be able to monitor the usage on my phone. Excellent service all round!

First time customer and couldn’t be happier. Upgraded my Solar battery system (added to) and process was so easy from order to installation. Luke who did the installation was fantastic, install was completed in a timely manner and thoroughly cleaned up after. After sales follow up to ensure all went as expected. I highly recommend 1 KOMMA5.

Powerwall3 battery setup in Brisbane

Jayden did a great job with the installation of the batteries. He communicated well prior and throughout the installation. Also walked me through the App setup and provided support to an issue with the battery system within the first week.
