Australia purchase checks
Make the shortlist quote-ready
These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.
- Lock the exact model and installation-date listing.
Ask for every model number to appear on the quote and order. The Clean Energy Council product lists are live: STC creation requires listed products at installation, and network requirements may also depend on current approval.
- Obtain the site-specific connection settings.
Have the retailer state the supply phase, inverter connection limit, export limit and any export-control cost. The local network connection agreement, not a generic datasheet, determines those settings. See the Australian Government's connection guidance.
- Test savings against the household, not a brochure.
Ask which bills or interval data, tariff, feed-in rate, export limit and future loads support the savings and payback claim. Self-consumed electricity and tariff timing usually matter more than a headline feed-in rate. See the system sizing and battery savings guidance.
- Specify the operating outcome.
Define the usable energy, output power, backed-up circuits and outage behaviour. Confirm whether VPP participation, an internet connection, or an additional controller changes the configuration, reserve level, warranty or support path.
- Name the party responsible after installation.
Keep the retailer, installer, manufacturer warranty and escalation path in the contract. Australian Consumer Law guarantees apply separately from any manufacturer warranty; where one business supplied both product and installation, it is generally responsible for the remedy. See the ACCC guidance.
