Sonergy holds a Clean Energy Regulator licence to trade Small-scale Technology Certificates (STCs) — and we put it to work for homeowners, installers and businesses across Australia, with transparent pricing and fast payment, every time.
Every eligible solar, battery, solar hot water or heat pump system installed in Australia earns Small-scale Technology Certificates (STCs) — tradeable certificates created under the federal government's Small-scale Renewable Energy Scheme (SRES).
One STC broadly represents one megawatt-hour of renewable electricity generated or displaced by your system. The number you receive depends on your system's size, your location's solar zone, and the years remaining until the scheme winds down in 2030.
Most households assign their STCs to their installer upfront as a point-of-sale discount. But STCs can also be created, held and sold separately — and that's where Sonergy comes in.
Get a rough estimate of how many STCs your system may earn. This is a guide only, not an accurate or final figure. Sonergy confirms your exact entitlement and offer once we review your system details.
We've been active in the STC market since 2023. That means real relationships with liable entities, a working understanding of quarterly compliance cycles, and a straightforward process for getting you paid.
Sonergy holds an official Clean Energy Regulator licence to trade STCs — not every buyer in this market does. That licence means you're dealing with an authorised, accountable party at every step.
We track market pricing daily and quote you a clear rate before you commit — no hidden spreads.
Once your STCs are validated in the REC Registry, we move quickly on payment — no waiting for quarterly surrender windows.
Whether you're an installer with a pipeline of certificates or a business holding a large parcel, we handle volume.
We help you decide whether to sell now or hold for a quarterly surrender peak, based on where the market's heading.
From eligibility checks to REC Registry creation to final sale — we manage the paperwork so you don't have to.
Four steps, start to finish.
Tell us about your system — solar PV, battery, solar hot water or heat pump — and we confirm how many STCs it's entitled to.
