How to read STCs and feed-in tariffs in a quote.

Program settings, export arrangements and retailer plans can change. Current treatment should be visible in the written proposal and checked against the official source.

Verification first: eligibility, certificate treatment, retailer plans and export settings can change. This guide does not state current eligibility or dollar values.

Where STC treatment may appear

Small-scale technology certificates (STCs) are part of the Australian Government’s Small-scale Renewable Energy Scheme. The Clean Energy Regulator explains that many system owners assign the right to create certificates to a registered agent in exchange for an upfront discount. A quote should show clearly whether and where that treatment has been applied.

Feed-in tariffs are retailer settings

A feed-in tariff is part of an electricity retailer plan, not a guaranteed solar return. The rate, conditions and whole plan can change. Compare exported energy with energy used directly at the property, and check the current plan through the retailer or the government’s Energy Made Easy service.

Export settings are a separate site question

The amount a site can export is not set by the feed-in tariff. Network connection settings, compatible equipment and the property’s circumstances matter. SA Power Networks publishes the current Flexible Exports information for South Australia.

Questions to ask before relying on a figure

  • Where is STC treatment shown in the proposal?
  • Which official information was checked and on what date?
  • Which current retailer plan is being used?
  • How much generation is expected to be used on site and exported?
  • Which export setting is proposed for the property?
