Solar Savings Calculator by State: What You’ll Actually Save in 2026
Solar savings used to be a fairly simple national number: knock 30% off the system cost, then calculate payback from there. That’s no longer true. With the federal credit gone for owner-installed systems, your savings now depend almost entirely on which state you live in — specifically, your electricity rate, your net metering policy, and whatever state-level incentives are still on the books.

Why state matters more than it used to
Three factors now do all the work the federal credit used to help with:
- Electricity rate. States with high per-kWh rates (much of the Northeast and California) see solar pay off faster simply because every kWh you generate is worth more.
- Net metering policy. Full retail net metering (you’re credited the same rate you’d pay) makes solar far more valuable than states that pay a lower wholesale rate for excess power sent back to the grid.
- State tax credits and rebates. A shrinking number of states still offer their own credit or rebate program on top of net metering — check the current list at your state energy office or the DSIRE database (Database of State Incentives for Renewables & Efficiency), since these change often and shouldn’t be assumed from an old article.
What didn’t change
Panel efficiency, average system lifespan (25+ years), and the basic economics of “the sun is free after installation” are unaffected by the 2026 policy shift. What changed is how fast you get your money back, not whether solar works.
Should you wait for federal policy to change again?
Federal energy policy has shifted twice in the last four years already. Waiting for another change is a bet, not a plan — the more reliable approach is to calculate your payback period using current state and utility numbers, decide if that timeline works for you, and treat any future federal reinstatement as a bonus rather than something to plan around.

FAQ
it varies significantly. Some states still have meaningful credits or rebates; others rely entirely on net metering with no additional state credit. Check DSIRE or your state energy office for what’s current.
It depends heavily on your state’s electricity rate and net metering policy. In high-rate states with full retail net metering, the case is still strong. In low-rate states that also cut the federal credit’s benefit, the payback period can stretch considerably.
The full system cost now applies with no federal reduction for owner-installed systems (unless you go the lease/PPA route — see our solar tax credit article). Get quotes from installers for your specific home rather than relying on national averages, since local labor and permitting costs vary widely.
Yes — third-party-owned systems (leases and PPAs) can still access the federal 48E credit through 2027, which the leasing company typically factors into your rate.
