Understand this: Australia’s battery market is on the verge of a multi-year boom — one that could see over one million batteries installed over the next five years.
That’s a scale large enough to reshape the industry, attract dozens of new entrants, and redistribute market share dramatically. It also presents an unprecedented opportunity for manufacturers, distributors, and retailers — but only for those who are prepared.
Success in this environment requires a clear view of the present and a well-informed outlook on the future.
The Boom Will Be Uneven — and That’s Strategic Gold
The coming growth won’t be linear. Based on SunWiz’s latest research — informed by market-leading battery brands, independent forecasters, and our own detailed modelling — the rollout of these one million batteries will be back-loaded and constrained by a key bottleneck:
Installer availability.
Currently, less than half of accredited solar installers are licensed to install grid-connected battery systems. That effectively limits the short-term ceiling to around 150,000 ESS installations per year — approximately half the annual PV installation volume.
This constraint will ease over time, but it creates a critical window where:
- Growth is real, but capped
- Brands must secure loyal installer networks early
- Support, training, and ease-of-installation are major competitive advantages
Batteries Will Soon Lead Solar — Not Follow It
Historically, batteries have been added to support new PV systems. That’s changing.
Thanks to:
- A surge in retrofit battery demand
- PV system upgrades
- Rising interest in energy independence and grid resilience
…we’re approaching a tipping point where more batteries will be installed each year than greenfield PV systems.
In other words, batteries will become the primary market driver, pulling PV installations along with them — a reversal of the industry dynamic we’ve known for years.
Forecasts Are a Compass — Not a Crystal Ball
Let’s be clear: no forecast will be perfectly accurate. But the value of forecasting isn’t in predicting the future — it’s in setting strategic, defensible targets and guiding ongoing decisions.
The battery market will shift quickly, and those who monitor and adjust regularly will stay in the sweet spot of growth.
That’s why continual tracking is essential — not just yearly, but monthly.
