Short answer: Every U.S. homeowner qualifies for the 30% federal Investment Tax Credit (ITC) through 2032. On top of that, 40+ states offer additional rebates, tax credits, property tax exemptions, and/or SREC markets. In the strongest stacks — New Jersey, Massachusetts, Illinois, Maryland — combined incentives can cover 45–60% of system cost.
The federal Investment Tax Credit (ITC) — how it works
The federal solar ITC, extended through 2032 by the Inflation Reduction Act, gives homeowners a 30% credit on their federal income tax for the total installed cost of a solar system — panels, inverter, labor, permits, and an optional battery.
- Eligible: New solar system, battery storage (≥3 kWh), and associated soft costs (permits, interconnection fees).
- Not eligible: Roof repairs unrelated to the mount, extended service warranties, landscaping.
- How to claim: IRS Form 5695, filed with your annual return. The credit is non-refundable — you need enough tax liability to absorb it, but unused portions carry forward up to 5 years.
- Add-on bonuses: +10% for domestic content (panels from US-manufactured cells), +10% for low-income or energy community qualifying zones. Check with a tax professional.
- Step-down schedule: 30% through 2032, 26% in 2033, 22% in 2034, 0% for residential after 2034 (subject to legislative change).

SREC markets explained
A Solar Renewable Energy Credit (SREC) is a tradable certificate issued for every 1,000 kWh (1 MWh) your solar system produces. Utilities in SREC states must source a minimum percentage of their electricity from solar — they buy SRECs from homeowners to meet that quota. The price fluctuates based on supply and demand in each state's market.
- Strong SREC markets ($40–$85 per MWh in 2026): New Jersey (SuSI TRECs), Massachusetts (SMART), Maryland, Illinois (Adjustable Block).
- Moderate SREC markets ($20–$40): Pennsylvania, Washington DC.
- Weak SREC markets ($4–$20): Ohio — low solar carve-out makes these nearly worthless.
A typical 8 kW system produces ~11 SRECs per year. At $80/SREC in NJ, that's $880/year — $13,200 over the 15-year program term.
How incentives stack
The key rules for stacking in 2026:
- Federal ITC + state tax credits: Always stack. Claim both in the same tax year.
- Federal ITC + utility rebate: Stacks, but the rebate reduces the ITC basis. A $3,000 utility rebate on a $25,000 system lowers the ITC basis to $22,000, dropping the credit by ~$900.
- Federal ITC + SRECs: Stack cleanly. SREC income is reported separately as taxable income.
- State rebate + state tax credit + property tax exemption: Generally all stack. Confirm with state DOR.
- SGIP (CA) + ITC: Stacks. SGIP is considered a rebate, not a grant, so the ITC basis is reduced slightly.
Example stack: New Jersey homeowner, 8 kW system, $24,000 gross cost
- Federal ITC (30% × $24,000): −$7,200
- NJ sales tax exemption (6.625% waived): saves $1,590 upfront
- Property tax exemption: no added assessment (preserves ~$300/year)
- SuSI TRECs (11/year × $85 × 15 years): +$14,025 lifetime
- Effective net cost after ITC and TRECs: ~$2,775 over 15 years
This level of combined incentive is why NJ consistently ranks among the top 3 U.S. states for residential solar ROI.

Frequently asked questions
What is the federal solar tax credit in 2026?
The federal solar Investment Tax Credit (ITC) is 30% of the total installed cost of a solar system, including labor, permits, and an optional battery. It remains at 30% through 2032, steps down to 26% in 2033 and 22% in 2034, and is zero for residential after 2034 under current law.
Which states have the best solar incentives in 2026?
New Jersey, Massachusetts, Illinois, and Maryland rank highest in combined value, with SREC markets paying \$40–\$85 per MWh for 15 years on top of the federal 30% credit. In some stacks, total incentives cover 45–60% of installed system cost.
Can I stack state and federal solar incentives?
Yes. State tax credits and property tax exemptions stack cleanly with the federal 30% ITC. Utility rebates also stack but reduce the ITC basis — a \$3,000 rebate lowers the ITC-eligible cost by \$3,000, shrinking the credit by about \$900.
What is an SREC and how much is it worth?
An SREC (Solar Renewable Energy Credit) is a tradable certificate issued for every 1,000 kWh a solar system produces. In 2026, NJ SuSI TRECs pay ~\$85 each, MD and IL SRECs pay \$50–\$80, PA runs ~\$40, and Ohio SRECs are nearly worthless at \$4–\$12.
