Seemless and stress free

From start to installation the whole process to painless and stress free. They kept me informed about every step of the process either through text or email. All of my thousands of questions were answered promptly and without judgement. Installation day went so incredibly smoothly I didn't even notice they were installing solar into my roof. Everyone i interacted with either by phone or in person were so incredible polite and helpful. I cannot recommend this company enough.

Professional install and slick app

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.

From the first phone call and home…

From the first phone call and home visit,sign up, to installation we were kept informed about every step of the process either by text or email. Any questions were answered promptly and accurately. Installation day went without a hitch. Once installed I was shown how to use the online app and the shut down process. The installer waspolite and informative. 10/10.
All persons dealt with were super professional.
Special thanks to Jake White for organising everything.👍

From the initial enquiry/pricing and…

From the initial enquiry/pricing and discussion with Nicole to the final installation it all went smoothly. A couple of follow up emails required at times but hey the company is doing a lot of work.

Nicole was fantastic in keeping me abreast of where things were at.

The informative presentation video by the CEO I thought was excellent (simple but with all required information to base your decision.

Jamie (pretty sure name is correct) installed on site and was very professional and once again kept me informed.

Torston Jamie's immediate boss you could tell was across the whole installation even though he was obviously running multiple installs.

Basically I KOMMA5degrees run the whole operation as a well oiled machine through each and every step.

Yep I will be recommending them. I've been in the construction industry for over 40 years (management) so I know when I see a good company.

Cheers

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.
