Is solar worth it in Australia in 2026?

For most Australian homeowners, yes, a typical system pays back in 3–5 years, then generates near-free power for 20+. Here's when solar is worth it, and when to think twice.

For most Australian homeowners in 2026, yes, solar panels are worth it. A typical 6.6 kW system pays for itself in 3 to 5 years and then generates effectively free electricity for another 20+ years. But it isn't automatic: the return depends on how much power you use during daylight, your feed-in tariff, and your state's rebates.

The short answer, by situation

Worth it: you own your home, have a north/east/west-facing roof with little shading, and use power during the day (or can shift usage, pool pump, hot water, EV charging).
Still usually worth it: you're out during the day. Payback stretches to 5–7 years, or add a battery to use your solar at night.
Think twice: a heavily shaded roof, you're moving within 2–3 years, or you rent (ask your landlord about a rent-shared system).

The numbers

A 6.6 kW system costs roughly $5,800–$7,500 installed, dropping to about $4,000–$6,000 after the federal STC rebate. It generates around 9,000–10,000 kWh a year. Self-consume half and export half and you typically save $1,200–$1,800 a year, a 3–5 year payback, then 20+ years of savings. See current pricing on our solar price index.

Is a battery worth it too?

That's a separate question. With the federal Cheaper Home Batteries rebate now cutting roughly 30% off, battery payback has fallen to 5–8 years in states that stack a rebate (NSW, WA, ACT). Compare options in our best home batteries guide.

Common questions

Is solar still worth it in 2026?

Yes for most owner-occupiers. Payback on a 6.6 kW system is typically 3–5 years thanks to high electricity prices and the federal STC rebate, leaving 20+ years of savings. It's worth less if your roof is heavily shaded or you're rarely home during the day.

Is solar worth it if I'm not home during the day?

It still helps, appliances on timers (hot water, pool pump, dishwasher) soak up daytime solar, and exports earn a feed-in credit. But if most of your use is at night, a battery is what makes solar really pay for you.

How long until solar pays for itself?

Usually 3–5 years for panels in Australia. After that the electricity savings are yours for the remaining 20+ years of the system's life.
