Aldi Solar went live in metropolitan Western Australia and South Australia on 5 August 2026, putting fixed-price solar and battery packages in front of Perth and Adelaide households for the first time. Prices start at $7,499 for 7kW of solar with a 5kWh battery, with the federal Cheaper Home Batteries rebate already deducted. It is a genuinely cheap way in. It is also worth understanding exactly what you are buying before you click.
What is on the menu
- 7kW solar with a 5kWh battery: $7,499
- 7kW solar with a 10kWh battery: $8,499
- 7kW solar with a 15kWh battery: $9,499
- 7.9kW solar with a 20kWh battery: $10,999
- Battery only for existing solar owners: $5,499 for 15kWh or $6,499 for 20kWh
Every package includes a 6kW smart hybrid inverter, installation, blackout protection, a 10 year system warranty and a 25 year panel performance guarantee. The federal battery rebate is baked into the advertised price rather than claimed separately, which removes a real source of confusion for first time buyers.
The costs that are not in the headline price
Aldi Solar's own installation page lists extras that apply depending on your house. None of them are unusual in the solar industry. What is unusual is how easily they can be missed when the pitch is a single fixed price.
- Fire-resistant panel, required for weatherboard or timber homes: $385
- Two-storey property surcharge: $275
- Inverter mounted more than 6 metres from the switchboard: $390
- Three-phase load meter upgrade: $350
- Smart meter if you do not already have one: no fixed price, arranged through your retailer
Stack two or three of those and you can add roughly $1,000 to the bill. A single-storey brick home on single-phase power will usually avoid all of them.
Aldi is not the installer
This is the part worth knowing. Aldi does not supply or install any of it. It licenses the Aldi Solar name to Tempo (Aust) Pty Ltd, and Tempo is the party your contract and your warranties sit with. SolarQuotes, which has been tracking the offer since its Melbourne trial in early 2025, reports that the terms and conditions state no site visit occurs before the system is designed. Design is done from aerial imagery and photos supplied by the customer.
Asked about this, Aldi Solar said its proposals are generated using Pylon solar design software, which is widely used in the industry, and that accredited installers verify the design and discuss any adjustments on site with the customer before work starts. It also said every installer holds a current electrical licence and SAA accreditation, that component serial numbers and geo-tagged photos are tracked at every stage, and that every customer receives an owner's manual and a certificate of compliance.
One number in that response is worth reading twice. Aldi Solar audits 100 percent of jobs in Victoria with independent post-installation inspections, and 25 percent everywhere else. Everyone in this week's WA and SA rollout falls into the 25 percent bucket, which means three in four installs get no independent check.
What to do if you are tempted
- Know that Tempo, not Aldi, holds your contract and your warranties
- Check your specific installer's accreditation directly with Solar Accreditation Australia
- Ask what the extras will cost for your house before you commit, not after
- Get at least one comparison quote from an installer willing to physically inspect your roof
- Photograph the install yourself, especially outside Victoria
The WattsUp take
A fixed-price package genuinely suits some houses: single storey, no shading, standard roof, owner who wants a decision made rather than a spreadsheet built. For those buyers this is a reasonable deal and the rebate handling is the cleanest we have seen. For everyone else, a system designed off satellite photos for a roof nobody visited is a trade-off, not a bargain. Solar sits on your house for 25 years. Spend an afternoon getting a second quote.
