Solar savings calculator.
Modeled with PVWatts - the U.S. government's solar production model (National Laboratory of the Rockies, formerly NREL). Enter your city and average electric bill.
How this works
How much can solar panels save me?
For a typical US home: $1,500-$2,500 per year in avoided electricity, with payback in 8-14 years depending on local sun, rates, and system cost. After payback, production is effectively free power for the panels' 25+ year life.
Why is this more accurate than other calculators?
Production comes from PVWatts - the Department of Energy's standard photovoltaic model (National Laboratory of the Rockies, formerly NREL) - instead of a flat sun-hours guess. The savings math uses current 2026 incentive rules, 0.5%/yr panel degradation, and 2.5%/yr utility rate escalation.
Is there still a federal solar tax credit in 2026?
Not for systems you buy: the 30% residential credit (Section 25D) ended December 31, 2025. Leased and PPA systems can still benefit - the installer's business claims a credit (Section 48E, through 2027) that can lower your rate. Many states also run their own incentives; check DSIRE for local programs.
Is this a quote?
No - it's a planning estimate from modeled production and typical installed costs. An installer confirms pricing with a site survey, roof measurements, and your utility's net-metering terms.
