Are Solar Batteries Worth It in 2025?

With a Million Battery Subsidy on the Table, the Game Just Changed


For years, the economics of solar batteries in Australia were… borderline.

Today? That’s changed.

Thanks to plummeting feed-in tariffs, rising grid prices, and the potential for a federal subsidy program that could deliver up to one million discounted home batteries, the question has shifted from “Should I wait?” to:

“Why wouldn’t I take advantage of this now?”

Here’s what you need to know.


🏛️ Big News: A National Battery Program Could Be on the Way

The Australian Labor Party (ALP) has pledged to roll out 1 million subsidised solar batteries if re-elected in 2025. This would be a nationwide program, working through local solar retailers and designed to:

  • Cut bills for households and small businesses

  • Reduce pressure on the energy grid

  • Increase energy independence across the country

The plan would start from mid-2025—but smart buyers are already preparing, because demand will spike as soon as the scheme kicks off.

💸 What Do Batteries Cost Right Now?

Here’s the 2025 ballpark:

  • Home systems: $8,000–$15,000 (10–13kWh)

  • Business setups: $15,000–$30,000+ (15–30kWh+)

  • Smart inverter + battery bundles: Slightly higher, but often rebate-eligible

That upfront cost can be daunting—but let’s zoom out:


📈 Payback Periods Are Getting Shorter

Why? Because the old solar game—“export your excess power to the grid”—is no longer profitable. With feed-in tariffs often as low as 5¢ or even 0¢, the real value comes from using your own power.

Here’s a simplified case:

  • 10kWh battery stores excess solar

  • Grid power costs $0.30–$0.45/kWh

  • Every stored kWh used at night saves ~$0.35

👉 That’s around $1,000–$1,400/year in potential bill savings.
👉 Payback: 7–10 years for most households, often faster for businesses with higher usage and tax offsets.


🧮 Rebates + Subsidies: What's Already Available?

While the federal battery scheme is pending election outcome, these current programs may still apply:

  • Victoria: Interest-free loans up to $8,800

  • Businesses nationwide: Accelerated depreciation + clean tech tax incentives

  • SA (previously): Home Battery Scheme closed, but future rounds may return under new federal/state alignment


🔋 Should You Wait?

Here’s the honest take:

✅ If you’re ready to move now, you’ll benefit immediately—no need to wait for Labor’s program.
✅ If you want to wait for a potential subsidy, get your site assessed and quote locked in now—before stock and installer capacity become scarce.


🔒 Bonus Benefits (Beyond the Payback)

  • Blackout protection during storms or grid outages

  • Control over energy bills, especially in peak summer pricing

  • Virtual Power Plant eligibility (earn credits by supporting the grid)

  • Peace of mind in a volatile energy market


🚀 Your Next Move

Whether you want to go now—or be ready the second a rebate drops:

Either way, the smart move is to start now, not wait for the rush.
