Is Solar Worth It in Queensland in 2026? An Honest Look

Short answer: for most Queensland homes, rooftop solar still stacks up in 2026 — but for a very different reason than it did a decade ago. Back then you were paid handsomely to export. Today the money is in the power you use from your own roof, not what you sell back. Whether solar is worth it for your household now hinges on three things: where you live (south-east versus regional), how much you can self-consume, and what you actually pay for the system.

South-east versus regional: two different feed-in worlds

Queensland runs two distinct distribution networks, and they treat your exports differently.

• South-east QLD (Energex): the feed-in tariff is market-set by your retailer, with no regulated minimum. Rates here sit within the typical Australian band of roughly 3–10c per kWh and have trended down for years.
• Regional QLD (Ergon): the Queensland Competition Authority (QCA) sets a regulated rate. For 2026-27 (from 1 July 2026) that rate is 6.006c per kWh.

Confirm which network your address falls under before you assume anything — it changes the maths. Either way, note how modest these numbers are. At 6c, exporting a kilowatt-hour earns you a fraction of what you'd pay to buy it back at night.

Why self-consumption is the whole game now

The single most important number for your payback isn't the feed-in tariff — it's the share of your solar generation you use directly instead of importing from the grid. Every kWh you self-consume avoids a retail import charge (often many times higher than any feed-in rate). Every kWh you export earns only that small feed-in figure.

That flips the old advice on its head. A big system that exports most of its output into a low feed-in tariff is far less valuable than a right-sized system matched to when you actually use power.

What a system costs in 2026

Queensland has no state solar rebate — the only upfront discount is the federal Small-scale Renewable Energy Scheme (STCs), already baked into the "after STC" prices below. Indicative installed costs in QLD:

System size	Typical price after STCs
6.6 kW	$4,000 – $6,500
10 kW	$7,500 – $12,000
13.2 kW	$9,000 – $16,000

At a Queensland yield of around 1,400 kWh per kW per year, a 6.6 kW system generates roughly 9,200 kWh annually. On a single-phase connection the standard export limit is 5 kW, which quietly caps how much a very large array can send back — another reason bigger isn't automatically better.

Here's the catch — when solar might not pay (fast)

Solar is not a guaranteed win for every household. It can disappoint if:

• Nobody's home during the day and you can't shift load. If most generation is exported at ~6c while you buy it back on a peak tariff, the gap between export value and import cost is doing you few favours.
• You're in SE QLD on a shrinking market feed-in tariff and oversize the system hoping export income will carry it. It won't — exports are the low-value part now.
• You're on a time-of-use plan (peak typically 4–9pm daily on Energex/Ergon) with high evening use. Solar does little for a 7pm load — that's a battery or behaviour conversation, not a bigger-array one.

For the right-sized, daytime-using household, payback is commonly in the several-years range and solar is clearly worth it. For the wrong profile, the numbers are much softer — and no amount of sales enthusiasm changes that.

What about adding a battery?

Batteries attract the federal Cheaper Home Batteries discount (via battery STCs), indicatively around $250–$300 per usable kWh in 2026 — an estimate, as the STC price floats. The STC factor is 6.8 per usable kWh from May to December 2026, then steps down (it drops to around 5.7 per kWh on 1 January 2027 and reduces each half-year to 2030). The discount is tiered: 100% of the factor on the first 14 kWh, 60% on 14–28 kWh, 15% on 28–50 kWh. Queensland adds no state battery incentive. Typical battery payback sits around 8 years — worth modelling against your actual evening usage, not assuming.

Please treat every figure here as a starting point: confirm your network, your current feed-in rate and your actual plan before committing. We don't sell or install anything, so these numbers are the whole story — not a lead-in to a quote.

We sell no panels, no batteries, no plans — just an engineered look at your bill, your roof and your routine. Sometimes that means "yes, size it like this." Sometimes it means "honestly, solar won't pay for you yet." Either way, you get the answer that's true for your home, not the one that sells a system.

Figures in this guide are current at the date of publication and indicative only — rebate and certificate values change over time (federal battery certificates step down each January and July), and state schemes are amended often. Confirm the current numbers for your situation before you commit. This is general information, not personal financial advice.
