Three Numbers That Change Everything
Solar economics reduce to three numbers. Your current bill. The savings solar produces against it. And what you actually keep paying. Every other figure on this site flows from these.
The monthly utility bill you pay today, on a $0.14/kWh national average.
The portion replaced by your rooftop solar production over a 25-year system life.
What's left: small grid connection fees and minor draw on cloudy days.
Federal residential credit: $0.
The 30% federal residential solar credit has ended. Under P.L. 119-21, the §25D Residential Clean Energy Credit terminated for expenditures made after Dec 31, 2025 — a system installed in 2026 cannot claim it. So the honest question in 2026 is: does solar still pay in your state without the federal credit? Run the math with $0 federal credit plus your state's incentives.

Commercial solar is a different credit from the residential one that ended. Commonly cited Section 48E percentages and depreciation benefits are not a settled quote.
Commercial solar (§48E) is different — but the clock moved. Projects that missed the Jul 4, 2026 beginning-of-construction deadline generally must be placed in service by Dec 31, 2027. Figures on this page are general information, reviewed Oct 2026, not tax advice.
Explore by Incentive Type
The federal residential credit is $0 for a 2026 install. What remains is state credit, net metering, SRECs, exemptions, and utility rebates.
Net metering credits homeowners for excess solar energy sent back to the grid, often at retail or near-retail rates.
Solar Renewable Energy Certificates (SRECs) are tradable credits earned for every megawatt-hour of solar electricity produced.
A solar property tax exemption excludes the added home value from solar from your annual property tax assessment.
Solar sales tax exemptions remove state and local sales tax from solar equipment purchases at the point of sale.
Several states still offer their own income tax credits for residential solar. The federal residential credit does not apply to a 2026 install.
Many electric utilities offer upfront rebates that lower the cost of solar installation, typically distributed first-come, first-served.
