Yes — the figures here assume the STC rebate is applied at point of sale, which is how nearly all retailers quote.

It depends on your tariff and self-consumption patterns. Batteries typically have a 7–11 year payback in 2026, but improve resilience and energy independence regardless.

In most states a standard rooftop system is exempt development, so no council approval is needed. The usual exceptions are heritage-listed homes, tilt frames on flat roofs, and strata properties, where you'll need owners corporation consent. Your installer must also obtain grid connection approval from your electricity distributor, which they normally arrange before work starts.

Most single-storey residential systems go on in a single day; two-storey homes, tile roofs and battery installs can stretch to two or three. The longer waits are administrative: grid connection approval before the install, then a meter reconfiguration by your retailer afterwards, which can take a few weeks before you're credited for exports.

The system must be designed and installed by an accredited installer (Solar Accreditation Australia, formerly Clean Energy Council accreditation) to qualify for the STC rebate, and all wiring must be done by a licensed electrician. Ask to see the accreditation of the person actually attending your roof, not just the company selling the job, as subcontracting is common.

Check each quote names the exact panel and inverter make and model, not just a tier or wattage. Confirm the same inclusions across quotes: mounting for your roof type, grid connection paperwork, and any switchboard work, which is a common extra. Compare warranties separately too, as product, performance and workmanship warranties are different things, and the installer's workmanship warranty is the one you're most likely to use.
