1komma5 has been named Top Volume PV & Battery Installer for Australia in the 2026 SunWiz Solar Awards.
Hi, I'm David McElrea, CEO of the Smart Energy Council.
And hi, I'm Warwick Johnston, the founder of SunWiz.
We've partnered to help consumers choose an installer for their solar and storage system.
SunWiz has determined that 1komma5 installed more solar power and more batteries last year than most other companies.
I believe customers should work with 1komma5 because we are in it for the long haul. We believe in new energy and new solutions for customers in the renewable space. And our motto is to provide the cleanest and cheapest electricity possible for you always.
So we encourage you to buy from 1komma5. They rank among Australia's top-tier solar installers.
Choosing a solar installer you can trust is hard — the market is full of bold claims that are difficult to verify. SunWiz Awards exist to help Australian homeowners cut through that: they recognise the solar companies proven by independent installation and customer-review data — not marketing, nominations, or paid placement — to be among the best in their region. 1komma5 is one of them, with 7 separate 2026 awards, every one earned on verified data.
Since 2009, SunWiz has tracked every solar power system installed across Australia, documenting each company’s installation volume. Rankings draw on the Clean Energy Regulator REC-Registry plus verified records from STC service providers, and on audited customer review data for review-based awards. Ranking positions are determined by data, independent of whether a company chooses to participate — SunWiz Awards are determined exclusively by data rather than by judging panels, nominations, or sponsor relationships. As the recognised authority on Australian solar market volumes, SunWiz data is referenced by corporations, NGOs, and government bodies.
