The C&I market is turning: what the STC expansion and NSW’s battery subsidy mean nationally. A SunWiz webinar on Thursday 8 October 2026, 12:30–1:30pm AEDT, online.
Two policy changes are reshaping the Commercial & Industrial solar and battery market at the same time.
From 1 October, commercial PV systems from 100 kW to 1 MW can create upfront STCs instead of annual LGCs — the biggest shift to commercial solar economics in years. Alongside it, the NSW Peak Demand Reduction Scheme is now subsidising commercial batteries. NSW is the leading edge here, and it’s an early indicator of where the national market is heading.
Put together, PV and storage stack up on more C&I sites than they did a year ago. For manufacturers and distributors, the question is where demand goes next — and how far the NSW signal travels.
In this session we read the market signals with SunWiz data, and bring in the businesses shaping the commercial pathway.
What you’ll take away
- A clear read on where C&I PV and battery demand is heading as the incentives land
- What the STC expansion and NSW’s battery subsidy change — and what NSW signals for the rest of the country
- Where the near-term risk and opportunity sit for the businesses supplying this market

The underlying demand is holding up well. The market is simply right-sizing, rotating out of oversized systems and into mid-scale storage in the twenty to thirty kilowatt-hour range, and SunWiz expects in the region of 350,000 battery installations across 2026, with rooftop solar currently at record levels.
