Is solar worth it in 2026?

The short answer

For a NSW homeowner with usable roof, a daytime-or-evening load worth offsetting, and a few years' horizon in the home: yes, and it isn't close. Well-designed systems routinely pay themselves off in 3-7 years and then generate essentially free power for decades. What's changed in 2026 is the shape of the case - it's now a solar-plus-storage question, and the strongest incentives sit on the battery side.

But 'most' is not 'all', and a site that only ever says yes isn't advising you - so the honest exceptions are below.

Why the case is strong right now

Three forces stack. Grid power remains expensive - NSW households commonly pay 30-40c/kWh - so every self-consumed solar kilowatt-hour is worth a lot. Hardware is historically cheap: panel prices have fallen for a decade, and a kilowatt of installed solar has never bought more. And the incentive window is genuinely favourable: STCs still discount solar upfront (declining each year to 2030), while the federal battery rebate discounts storage on a stepping-down schedule - meaning the same system is worth slightly less rebate next year than this one.

The old objection - 'feed-in tariffs are terrible now' - is true and misses the point. Exports were never the modern case. Self-consumption is, and batteries turn evening usage into self-consumption.

When the answer is no, or not yet

Renting (the roof isn't yours - our no-solar sustainability article is for you). Moving within a couple of years, where payback may not complete - though solar does add resale appeal. A heavily shaded or structurally tired roof, where remediation should come first. Very low usage - a frugal single-person household may simply not have enough bill to save. And apartments, where the path runs through strata rather than a sales quote.

If your situation is on this list, a good retailer says so. It's on ours because we mean it: the design tool will show you a weak case as readily as a strong one.

The 2026-specific angle: timing

Waiting has a price this cycle. STC deeming drops again each January; the battery rebate steps down on its published schedule; and network rules are shifting toward flexible exports, which well-specified new systems handle natively. None of this justifies pressure tactics - rebates decline on schedules, they don't vanish at midnight - but if you were already going to proceed, earlier captures more incentive than later, mechanically.

Balanced against that: hardware keeps cheapening. Historically the rebate step-downs have outpaced the price falls, which is why we lean 'sooner' for people who are otherwise ready - and say so with the reasoning attached.

How to answer it for your house

Generic articles - including this one - can only argue the general case. Your answer lives in your bill, your roof and your tariff, which is a fifteen-minute exercise in the design tool with every assumption editable. Run it; if the numbers stack up you'll see exactly why, and if they don't, you'll see that too.
