The battery STC price is the same as the solar STC price, because they are the same instrument. This page is about how it turns into dollars on a battery job, which is where it differs.
The spot price in context
At the time of writing the market has been roughly $38 to $40, and the clearing house will buy at $40, so the price cannot exceed that for long. Trader rates sit below spot, with the margin covering risk, registry work and speed.
What it means per job
| Battery | STCs (2026) | At $38 | At $40 |
|---|---|---|---|
| 10 kWh | 68 | $2,584 | $2,720 |
| 14 kWh | 95 | $3,610 | $3,800 |
| 28 kWh | 152 | $5,776 | $6,080 |
| 50 kWh | 174 | $6,612 | $6,960 |
A difference of 50 cents between two traders is about $48 on a 14 kWh job. Over a hundred jobs that is $4,800, worth chasing, but not at the cost of slower settlement.
Why volume matters now
Battery STCs have added a large flow of certificates to a market that had been mostly solar. The 2027 cuts in the factor to 5.7 and then 5.2 will reduce the number created per battery, though the number of batteries installed is high. For a view on how pricing moves day to day see STC price today and what an STC is worth.
Why the price matters more on batteries
A solar job creates around 45 STCs. A 14 kWh battery creates about 95. Rate differences therefore have double the effect per job, and a trader that is slightly cheaper on solar can look very different on battery volumes. Check your rate on your actual job mix, not just one product.
What this means for installers
Look at the rate you are actually paid, how it is locked, and how fast the money arrives. Our rates are on the pricing page, and the battery STC pillar covers the program. How it works explains lodgement and settlement.
