1KOMMA5° Sydney
The team at 1KOMMA5° as good as it gets. From my first interaction to final install, it was smooth sailing all the way. This is my third time using 1KOMMA5 °and won't be my last.
Scott M.
Everything was organised for me and all my questions answered. I was a little unsure about getting panels and which company to use but 1KOMMA5° made it very easy for me. They also have followed but to ensure that I am happy with their work.
With the whole process from paperwork to the whole installation everything was smooth. I can only highly recommend 1KOMMA5° and thank the whole staff for being so friendly and professional. Now we can sit back and enjoy our new solar.
