Australia's #1 Manufacturer for 2026
Recognised across 2 categories in the 2026 SunWiz Awards — for battery installations, equipment manufacturing across Australia.
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. SigEnergy is one of them, with 3 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.
SigEnergy is an Australian solar company that specializes in energy storage systems (ESS) and solar inverters, operating primarily in the Australian residential and behind-the-meter energy markets. The company has gained significant recognition in the Australian solar industry, winning three major categories at the 2026 SunWiz Awards: #1 BTM ESS, #1 Residential ESS, and #1 Fastest Growing Inverter. Their multiple award wins, particularly their recognition as the fastest growing inverter company, highlight their rapid expansion and strong performance in Australia's competitive renewable energy sector.
