How Solar Incentives Work in 2026
Solar in 2026 is supported by four types of incentives: the federal 25D Residential Clean Energy Credit, state solar rebates and tax credits, Solar Renewable Energy Certificates (SRECs), and net metering from your utility. These work differently — some reduce upfront cost, others generate ongoing revenue.
Federal 25D Tax Credit (30%)
30% of full system cost — panels, inverters, battery, installation. No cap. Claimed on IRS Form 5695. Nonrefundable but can carry forward. Locked at 30% through 2032.
State Credits & Rebates
New York up to $5,000. New Mexico 10% state credit. Oregon up to $6,000. Massachusetts SMART program. Each state is different — see table below.
Net Metering
Credits you for excess solar sent to the grid. Best in states with full retail-rate net metering. California's NEM 3.0 reduced export rates significantly in 2023.
SRECs / RECs
In some states (NJ, MA, IL), your system generates tradeable certificates you sell to utilities. Can add $500–$3,000/year depending on state SREC market price.
Solar Cost & Federal Credit by System Size
National averages for installed solar systems (panels + inverter + installation). State rebates reduce costs further. Prices vary significantly by region and installer.
| System Size | Avg Installed Cost | Federal Credit (30%) | After-Credit Cost | Est. Annual Savings |
|---|
| 5 kW (small home) | $13,000–$17,000 | $3,900–$5,100 | $9,100–$11,900 | $800–$1,200 |
| 8 kW (average home) | $20,000–$26,000 | $6,000–$7,800 | $14,000–$18,200 | $1,200–$1,800 |
| 10 kW (larger home) | $25,000–$32,000 | $7,500–$9,600 | $17,500–$22,400 | $1,500–$2,200 |
| 12 kW (with battery) | $35,000–$45,000 | $10,500–$13,500 | $24,500–$31,500 | $1,800–$2,600 |

FAQ — Solar Rebates
Can I get the 30% solar credit if I don't owe that much in taxes?
The 25D solar credit is nonrefundable — it reduces your tax bill to zero but won't generate a refund beyond what you owe. However, you can carry forward unused credit to future tax years. If your credit is $6,000 and you only owe $4,000 this year, you carry $2,000 forward to next year's return.
Does solar battery storage qualify for the 30% credit?
Yes — battery storage installed alongside solar panels qualifies for the full 30% credit. As of 2023, standalone battery storage (without solar) also qualifies for the 30% credit if it has capacity of at least 3 kWh. A $10,000 battery system would generate a $3,000 credit.
What is net metering and how much does it save?
Net metering credits you for excess solar electricity sent back to the grid, typically at retail electricity rates. The savings depend on your system size, local electricity rates, and how much you produce vs. consume. In states with full retail net metering and rates of $0.15–$0.25/kWh, a properly sized system can eliminate 70–100% of your electricity bill.
How long does it take to pay off solar panels?
The average solar payback period in the US is 7–12 years, depending on local electricity rates, solar resource, incentives, and system cost. After payback, the remaining 15–20 years of system life produce essentially free electricity. States with high electricity rates (California, New York, Massachusetts) typically see the fastest payback.
