How to Choose a Solar Battery Installer in SA (2026)

The short version: Choose a Clean Energy Council (CEC) accredited installer, get the full system spec and warranty in writing, and compare quotes on what’s actually included – not just the headline price. The cheapest quote is rarely the best value once you account for warranty, backup and workmanship.

A battery is a 10 to 15 year investment, and the installer matters as much as the battery brand. A good one sizes the system to your usage, handles the rebate paperwork, and is around to honour the warranty. Here’s how to pick one – and the red flags to walk away from.

1. Check CEC accreditation

The Clean Energy Council accredits solar and battery installers to a national standard, and CEC accreditation is required to claim the federal rebate. Ask for the installer’s accreditation and check it’s current. This is non-negotiable – it protects your safety, your warranty and your rebate.

2. Get the full spec in writing

A proper quote names the exact battery model, usable capacity, inverter, whether backup is included, and the VPP (if any). Vague quotes that just say “10kWh battery installed” make it impossible to compare. Insist on specifics.

3. Compare warranties properly

Product warranty – years and cycles on the battery itself (10 years is standard for quality brands).
End-of-warranty capacity – the percentage the battery is guaranteed to still hold.
Workmanship warranty – the installer’s own guarantee on the install.

4. Ask the right questions

Is the system sized to my actual usage, or a standard package?
Will it provide backup during a blackout, and is that included?
Which VPP do you recommend, and what are its terms?
Who handles the rebate paperwork? (It should be them.)
Do you subcontract the install, or do your own accredited team fit it?

Red flags to walk away from

High-pressure sales – “today only” pricing is a tactic, not a deal.
No CEC accreditation – or reluctance to show it.
A quote far below the rest – usually means a cheaper product, no backup, or cut corners.
Vague warranty terms – or a brand with no local support.
No site assessment – a real quote needs to see your roof and switchboard.

Choosing an installer – FAQs

What is CEC accreditation and why does it matter?

The Clean Energy Council accredits installers to a national safety and quality standard. It’s required to claim the federal rebate and protects your warranty and safety. Always confirm it’s current before signing.

How many quotes should I get?

Two or three is plenty if they’re detailed and from accredited installers. More important than quantity is comparing like for like – same battery size, same warranty terms, same inclusions.

Is the cheapest quote the best?

Rarely. A much lower quote usually means a cheaper product, no backup capability, or an under-sized system. Compare total value – warranty, inclusions and support – not just price.

Who claims the rebate, me or the installer?

Your accredited installer applies the federal rebate as a discount at the point of sale. You shouldn’t have to do the paperwork yourself.
