State Solar Incentives & Rebates 2025

The federal 30% ITC is just the start. Stack it with your state's tax credits, cash rebates, SREC income, and property tax exemptions to dramatically reduce your net solar cost. Here's what every major state offers.

Key State Programs Explained

🗽

New York — NY-Sun Initiative + State Tax Credit

New York has one of the strongest combined solar incentive packages in the US. The NY-Sun initiative provides additional incentives through utility programs (ranging from $0.20–$0.60/W depending on region and system size). On top of that, NY residents get a 25% state income tax credit on solar costs, up to a $5,000 maximum. Combined with strong net metering and a full property and sales tax exemption, New York is consistently ranked among the top solar states.

State tax credit: 25%, max $5,000
NY-Sun rebate: Varies by utility ($0.20–$0.60/W)
Net metering: Full retail credit

Massachusetts — SMART Program + State Credit

Massachusetts runs the Solar Massachusetts Renewable Target (SMART) program, a fixed-rate incentive paid by Eversource, National Grid, and Unitil to solar system owners for every kWh generated. Rates vary by utility and "capacity block" — earlier blocks get higher rates. MA also has a 15% state income tax credit (up to $1,000), full sales and property tax exemptions, and historically strong SREC income. One of the most comprehensive solar packages in the country.

SMART rate: Varies by block (~3–5¢/kWh additional)
State credit: 15%, max $1,000
SREC market: Active (SREC-I legacy)

New Jersey — TREC Program (Successor to SRECs)

New Jersey replaced its SREC market with Transition Renewable Energy Certificates (TRECs) for new systems. TRECs earn approximately $91 per MWh generated for residential systems, paid over 15 years — providing predictable long-term income. NJ also has full property and sales tax exemptions on solar equipment. Older NJ systems may still be earning under the legacy SREC-II program at higher prices.

TREC rate: ~$91/MWh (residential)
Contract: 15 years
Tax: No property or sales tax

California — SGIP Battery Rebate

Since NEM 3.0 significantly reduced California's solar export credits (to ~5¢/kWh), battery storage has become far more valuable for CA homeowners. The Self-Generation Incentive Program (SGIP) offers rebates on battery storage: standard rate is around $200/kWh, with enhanced rates up to $1,000/kWh for low-income households or those in high fire-risk areas. Applications are waitlisted by PG&E, SCE, and SoCalGas service territories.

SGIP standard: ~$200/kWh battery
Equity rate: Up to $1,000/kWh
NEM 3.0 export: ~5¢/kWh

Net Metering — What to Check in Your State

Net metering policies vary widely and can dramatically affect your solar ROI. Here's what matters most when evaluating your state's net metering rules:

Key questions to ask

  • ✦ Is credit at retail or wholesale rate?
  • ✦ Do unused credits roll over month-to-month?
  • ✦ Do credits expire annually?
  • ✦ Is there a system size cap for net metering?
  • ✦ Are there fixed charges that reduce savings?

Best & worst net metering states

Florida✅ Full retail NEM
New York✅ Full retail NEM
Texas✅ Varies by utility
California (NEM 3.0)⚠️ ~5¢/kWh
Alabama / TN❌ No mandate

🔍 Find every incentive for your address

The Database of State Incentives for Renewables & Efficiency (DSIRE) is the most comprehensive and up-to-date source of US solar incentives, maintained by NC State University with US Department of Energy funding. Enter your state at dsireusa.org to see every available incentive including local utility rebates.

Always verify current program availability — state budgets run out, programs open and close, and net metering rules change.

Frequently Asked Questions

Which state has the best solar incentives? ▼
New York and Massachusetts are consistently ranked among the best, offering substantial state income tax credits (NY up to $5,000; MA 15% up to $1,000), strong net metering rules, SREC markets, and active utility rebate programs. New Jersey leads on SREC value. California's SGIP battery rebate is the best battery-specific program. Texas and Florida have no state income tax, so state-level tax credits aren't applicable, but both offer strong property tax exemptions and good net metering.
Can I stack state incentives with the federal 30% ITC? ▼
Yes — state incentives stack on top of the federal ITC. However, note that if your state gives you a cash rebate, you'll typically reduce your federal ITC basis by the rebate amount (because your net cost is lower). State tax credits generally don't reduce your ITC basis. Always confirm with a CPA, as the interaction between incentives can be complex.
What is net metering and does my state have it? ▼
Net metering lets you send surplus solar electricity to the grid and receive credit at (or near) the retail electricity rate. 40+ states have mandatory net metering policies. California switched to NEM 3.0 in April 2023, which reduced export credits to around 5¢/kWh (down from ~30¢), making battery storage much more valuable there. States like Florida, New York, and Texas still have strong net metering. Check your utility's current interconnection tariff for exact rates.
What are SRECs and is my state eligible? ▼
Solar Renewable Energy Credits (SRECs) are certificates you earn for every 1,000 kWh your system generates. Utilities in states with solar carve-outs in their Renewable Portfolio Standards must buy these certificates to comply with the law, creating a market where you can sell your SRECs. Active SREC markets include New Jersey, Massachusetts, Maryland, Pennsylvania, Illinois, Ohio, and Washington DC. SREC prices vary widely — NJ trades at $200–$300 while PA is much lower.
Does going solar increase my property taxes? ▼
Solar typically adds 3–4% to home value. In most states this would normally trigger a property tax increase — but 36+ states specifically exempt the added value of solar installations from property tax reassessment. These exemptions are often automatic (no application needed), though rules vary. States with strong property tax exemptions include Arizona, California, Florida, Massachusetts, New Jersey, New York, and Texas.
Do I pay sales tax on solar panels? ▼
Around 25 states exempt solar equipment from sales tax, saving you 5–10% of system cost upfront. States with full sales tax exemptions include Arizona, Colorado, Massachusetts, Minnesota, New Jersey, New York, and Texas. Some states exempt only certain components (e.g., just the panels, not inverters), so confirm with your installer what's covered in your state.
