Best STC trader for batteries: fees and terms to compare
In short
There is no single best STC trader for batteries. The right one is the provider that pays the most net dollars per certificate, on terms you can verify, with a claim process that handles battery evidence. We name no winner and have not tested any provider's service.
Battery STCs behave like solar STCs in the market: they are the same certificate, they sell at the same price, and any registered buyer can take them. So “best trader for batteries” really means “best trader for your battery claims”. The differences are in fees, timing and how well the provider handles battery paperwork.
What to compare
| Item | What to ask | Why it matters |
|---|---|---|
| Rate | What is the dollar rate per STC today, and when is it fixed? | A rate that moves between lodgement and settlement is a different offer from a locked one |
| Fees | Is there any deduction, percentage, subscription or registry fee? | The headline rate is only meaningful after deductions |
| Settlement time | How long from a complete claim to cash in my account? | Cash flow on a 13.5 kWh battery is thousands of dollars |
| Claim checking | Who reviews the evidence before lodgement? | Battery evidence rules tightened from 1 March 2026 |
| Rejections | What happens if a certificate is invalidated? | Responsibility and clawback terms differ |
| Contact | Who do I deal with when something is wrong? | A named person beats a ticket queue |
| Exit | Can I leave, and what happens to claims in flight? | Avoid lock-in you did not notice |
Fee structures you will see
Providers describe their pricing in different ways, so convert everything to net dollars per STC on a standard claim.
- A published rate with no separate fees. The rate is the price.
- A rate less a fee per certificate or per claim. Subtract it.
- A percentage of proceeds. Depends on the price on the day; compute it at the current price.
- A subscription or platform fee. Spread it over your monthly volume.
- Software that creates and manages claims. A different service from buying; ask who pays you.
We have not published a table of named providers’ fees because we have not verified each one’s current terms, and fees move. For the same reason we do not rank them. If you want to see how the established options describe themselves, see STC aggregator, broker or platform, the STC trader comparison and how to compare STC traders.
Battery-specific questions
- Does the provider check serials, product listings and photos for batteries, not just solar?
- Does it know the current factor and tiers, so the STC figure in your quote matches the claim?
- Will it pay the same rate for battery STCs as solar STCs?
- How does it handle a claim that needs a correction?
Where Energy Merchants sits
We publish a daily rate on /pricing/, lock it when a complete claim is lodged, charge zero fees, and our compliance desk pre-checks each claim. Established partners settle within 24 hours; the first claim takes 48 to 72 hours. Settlement is backed by REC Traders, trading since 2004 and a Smart Energy Council member. That is a description of our terms, not a claim that we are best for everyone.
A one-page test you can run
Pick one real or recent battery claim. Send the same details to each provider you are considering: system capacity, installation date, product and the installer. Ask for a written statement of the rate that would apply, any deductions, the point at which the rate is fixed, and the expected settlement date. Put the answers side by side in a table and subtract deductions. If one provider will not give a written figure, record that too, because it tells you something about how a dispute would go. Repeat the test in a few months, as terms and rates move, and keep the file. This takes an hour once and gives you something no review page can: a comparison based on your own claim. For a deeper checklist, use the one linked below.
A fair verdict
Pick on net dollars, settlement time and claim checking, and put the answers in writing. For battery rules, see the battery STC pillar, our Cheaper Home Batteries installer guide and the choosing a certificate trader checklist. To see how we work, start at /start-trading/.
