Save thousands with federal STCs and state-level programs. The rebate reduces every year — act now to lock in the biggest discount.
The government's Small-scale Technology Certificate (STC) program provides an upfront discount on your solar installation.
When you install a qualifying solar system, it generates STCs based on system size and location.
Your installer typically handles the STC trade, applying the value as an upfront discount on your quote.
You pay the reduced price — typically $2,000–$4,000 less than the full system cost.
| System Size | Approx. STCs | Rebate Value* |
|---|---|---|
| 3kW | ~30 | $1,100 – $1,300 |
| 5kW | ~50 | $1,800 – $2,100 |
| 6.6kW | ~66 | $2,400 – $2,800 |
| 10kW | ~100 | $3,600 – $4,200 |
| 13kW+ | ~130+ | $4,700 – $5,500 |
*Values are estimates based on current STC trading prices.
The STC program phases down annually and ends in 2030. Each year you wait, you lose approximately 6–7% of the rebate value.
On top of the federal STC rebate, most states offer additional incentives.

A 6.6kW solar system typically generates around 66 STCs, worth approximately $2,400–$2,800. This is applied as an upfront discount by your installer, so you pay the reduced price.
