Big changes are coming for commercial solar.
From 1 October 2026, eligible solar systems between 100 kW and 1 MW can qualify under the expanded Small-scale Renewable Energy Scheme (SRES), giving larger commercial installations access to an upfront financial benefit through STCs.
For South Australian businesses, wineries, manufacturers and other high-energy users, it creates a significant opportunity to rethink whatโs possible for your site.
To put the potential savings into perspective:
โ๏ธ 250 kW system: approximately $68,000 in upfront savings
โ๏ธ 500 kW system: approximately $136,000 in upfront savings
While eligible systems can be installed from 1 October, the Clean Energy Regulator advises that STC applications for mid-scale systems will open in mid to late November 2026.
If commercial solar has been on your radar, now is the time to revisit the numbers.
