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

Solar still stacks up for a lot of Queensland homes — but not for the reasons the salesperson at your door is implying. In 2026 the money is no longer in selling power back to the grid; it's in using your own generation and dodging the retail price you'd otherwise pay. Whether that works for your roof depends heavily on where you live (south-east or regional), how much power you use during the day, and what you actually pay per system. Here's the honest version.

Two Queenslands: Energex vs Ergon

Your postcode changes the maths. QLD runs two distribution networks:

• Energex covers south-east QLD. Feed-in tariffs here are market-set with no regulated minimum — retailers can offer whatever they like, and it can be very low.
• Ergon Energy covers regional QLD. Here there's a QCA-regulated feed-in rate of 6.006c/kWh for 2026–27 (from 1 July 2026), so you have a guaranteed floor.

Confirm which network serves your address before trusting any feed-in figure — a quote built on a south-east rate is meaningless if you're on Ergon, and vice versa.

The feed-in reality (and why it's not the point)

Across the market, feed-in tariffs in QLD now typically land somewhere in the 3–10c/kWh range. Compare that to what you pay to buy power — usually several times higher. That gap is the whole story: exporting a kilowatt-hour earns you a few cents; not buying one saves you the full retail rate.

So the goal in 2026 isn't a big export cheque. It's self-consumption — running your appliances while the sun is up so you buy less from the grid.

What a system costs and roughly generates

QLD gets strong sun — plan on roughly 1,400 kWh per kW of panels per year. Indicative installed prices after the federal STC discount (already baked in) are:

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

One catch worth knowing: on a single-phase connection, export is commonly limited to 5 kW. A bigger array can still be worth it if you self-consume the extra, but don't let anyone sell you export you can't legally push to the grid.

There's no QLD state solar rebate — the federal STC scheme is the only subsidy, and it's already reflected in the prices above.

Free daytime power: Solar Sharer

From 1 July 2026, the federal Solar Sharer offer gives eligible customers free grid power in an 11am–2pm window, capped at 24 kWh/day, on participating retail plans. It's opt-in, requires a smart meter, and is confirmed as available in south-east QLD (Energex); regional Ergon customers should check whether their retailer participates.

This genuinely changes the calculus: if you can get free midday grid power, the case for oversizing solar purely to cover daytime loads softens. It's one more reason to look at your whole plan, not just the panels.

Honest payback — and when solar might NOT pay

For a household that uses a decent chunk of power during the day, a well-priced 6.6–10 kW system in QLD typically pays for itself in a handful of years, thanks to strong yield and good retail-rate offset. But it's not automatic:

• You're out all day and don't shift loads. If nearly everything you generate gets exported at 6c-ish, your savings shrink fast and payback stretches out.
• You're on Energex with a low market feed-in. Export earns very little, so the system only really pays through self-consumption.
• You overpay for the install. The price range above is wide — the difference between the top and bottom of the 10 kW band ($7,500 vs $12,000) can add years to payback for the same generation.
• Time-of-use traps. QLD peak windows are typically 4–9pm, after the sun's gone. Solar doesn't cover the evening peak unless you add a battery — and a battery is a separate investment with its own ~8-year payback.

On batteries: the federal Cheaper Home Batteries program discounts storage via STCs (an estimated ~$250–300 per usable kWh in 2026, though the underlying certificate price floats — verify at quote). There's no QLD state battery incentive. A battery can make sense if your evening use is high, but for many households solar alone with smart load-shifting is the better first move.

We don't sell or install a single panel, and we never will. Our only job is to run your actual bill, your roof, your network and your usage pattern through the numbers — and tell you plainly whether solar pays for you, or whether you'd be better off just shifting when you use power. Sometimes the honest answer is 'not yet'. That's exactly why we exist.
