1KOMMA5° South Australia

We had our solar and battery system installed by 1Komma5 in January and I honestly couldn’t be happier with the entire experience. From the very beginning, our sales manager Harry Evins was outstanding. He took the time to really understand our energy usage and worked closely with us to choose the best system for our needs, not just the most expensive option. He explained everything clearly, answered all our questions, and made the whole process straightforward and stress-free. The installation crew were just as impressive. Their workmanship was top-notch, they were professional, punctual, and left everything clean and tidy once the job was done. You can tell they take pride in their work. What really stood out was how quickly we could see the results. As soon as the system was installed and running, we could already see the savings, which was incredibly satisfying. On top of that, the turnaround time from signing the paperwork to installation was excellent. The whole process was smooth and efficient. If you’re considering solar and batteries, I highly recommend 1Komma5. A genuine 5-star experience from start to finish.

We have personally dealt with Kozco and 1Komma5 for solar and battery systems for our residential property, family and friends have also had there systems carried out by them. We also use them for our building company to service our customers with tailor made systems to suit there needs. Our system works seamlessly and we rarely get a power bill. Great return on investment. The app is simple and easy to monitor. We highly recommend 1Komma5 along with our sales rep Harry along with the installers who are friendly and very helpful Keep up the great work

Great experience with our solar battery installation. AJ was very helpful, knowledgeable, and took the time to explain everything clearly. The install went smoothly and we’re very happy with the result. Highly recommend.

I recently had a solar battery and inverter system installed by 1Komma5, and the entire experience was outstanding from start to finish. Shannon Knight (Sales) was knowledgeable, transparent, and incredibly easy to work with. He took the time to clearly explain the options, system sizing, and expected performance without any pressure. His advice felt honest and tailored to our needs, which made the decision process simple and confident. Bruce (Installer) delivered an exceptional installation. His workmanship was top-class — neat, clean, and highly professional. The setup looks incredibly tidy and well thought out, with great attention to detail. You can tell he takes real pride in doing the job properly. He also worked efficiently while keeping everything organised and safe. The whole process — from consultation to commissioning — was smooth, well-communicated, and professional. It’s refreshing to deal with a team that genuinely cares about quality and customer experience. I would highly recommend 1Komma5, Shannon, and Bruce to anyone considering a solar or battery installation.

I got my solar panels and batteries installed and the entire process from start to finish was made extremely pleasant. Harry Evins showed exemplary customer service and ensured I was happy with my price and product, choosing the best possible setup for me and my house. The servicemen who installed the panels and batteries were then incredible as well, conscious of my newborn inside and always advising us of any developments we should be aware of. Finally, after the installation, Harry contacted me to ensure I was happy with my service and again went above and beyond his customer service duties. 5/5 stars all around!

We had a fantastic experience with 1Komma5 for the installation of solar panels and batteries as part of our new home build. From start to finish, the process was smooth, professional, and well organised. Wayne was excellent to deal with — knowledgeable, responsive, and genuinely helpful. He took the time to explain the options clearly, made sure the system was tailored to our needs, and kept everything on track throughout the build process. The quality of the products and workmanship has been outstanding, and we’re really happy with the end result. I’d highly recommend 1Komma5 to anyone considering solar and battery solutions, especially if you want a team that knows how to work seamlessly with a new build. Thanks again to Wayne and the team.
