Should You Wait or Go Solar Now?
If you’re considering solar, now is the smartest time to act—the federal STC rebate drops every year, raising system prices while electricity tariffs continue to climb. Waiting doesn’t just cost you a larger upfront amount; it also means missing out on a full year of savings and protection from rising energy bills. Whether you’re looking at a 6 kW, 8 kW, 10 kW, 15 kW or 20 kW solar system with a battery, locking in today’s incentives and avoiding future price hikes can significantly reduce your long-term energy costs.

What’s Driving Solar Costs Down — and What’s Driving Them Up
- Average fully installed solar pricing in 2025 sits around $0.88–$0.95 per watt, but the real difference comes from STC rebates.
- As shown in the table, STC rebates are dropping across all system sizes — for example, a 10 kW system loses $455 in rebates if installed after the reduction (from $2,870 → $2,415).
- This means waiting directly increases your out-of-pocket cost, especially on larger systems like 15 kW and 20 kW, where rebate losses reach $700–$900+.
- Solar battery prices average around ~$1,390 per kWh, with brands like Tiito ranging $800–$1,400 per kWh, giving customers flexibility based on budget and performance.
- Battery prices are gradually improving, but STC rebates continue to shrink every year—making early installation the smarter financial move.
- Panels are already affordable, battery pricing is stabilizing, and delaying solar only reduces your rebate.
- If you’re planning solar + storage in Victoria, acting before the next STC drop locks in the highest savings on all system sizes.

STC Estimates Based On:
- Zone 3–4 averages (NSW + VIC)
- 2025 deeming period: 6 years
- Average zone rating: 1.382–1.468
STC Value Formula:
System Size (kW) × Zone Rating × 6 years × $35
These numbers can shift slightly depending on postcode zone (1–4), but the above is accurate enough.
Less STC Discount in the Future
The STC rebate is designed to shrink. As that happens, the upfront subsidy you get now will be higher than what’s on offer later. That could add thousands to your system cost if you delay.
Battery Prices May Not Fall Fast Enough
While battery prices are trending down, the rate of price decline may not offset the loss of STC benefits. Delaying could mean paying more both for the system and for storage.
Energy Prices Are Rising
Electricity costs are under pressure: grid constraints, inflation, and growing demand are pushing bills higher in many states, including Victoria. Going solar now helps you lock in lower long-term power costs.
Better ROI When You Act Early
By securing stronger rebates now, your payback period shortens. That means your system starts generating real value — not just clean energy, but financial return — faster.
