How payback works
12.5 yrs
Estimated payback

Saved per year
Solar's return is its payback period: annual bill savings against net system cost. In 2026, without the federal credit, that payback is longer but still real where rates and net metering are favorable.
Spot a fair quote in Dayton
A typical solar installation here runs $12,400–$16,200. A trustworthy quote shows a production estimate (kWh/year) and the net cost after incentives, not just a monthly payment. Be cautious of door-to-door pressure.
- Get the production estimate in kWh and the net cash price.
- Confirm the net-metering rate your utility currently pays.
- Compare buying vs lease/PPA; ownership keeps the long-run return.
What changes your price
- System size (kW). Sized to your annual usage and roof space; bigger arrays cost more but produce more.
- Panel tier & inverter. Premium high-efficiency panels and microinverters cost more per watt.
- Roof complexity. Steep, multi-plane, or shaded roofs add labor and may need more equipment.
- Battery storage. Adding storage roughly increases project cost by half but adds backup power and self-use value.

Why it matters
Why it pays to do it right
Lock in your electricity rate
Solar trades a volatile monthly bill for a fixed up-front cost, hedging against future utility rate increases over the system's life.
Payback is the real question
With the federal credit gone in 2026, the honest math is production times your local rate versus net cost. We show that payback plainly, no inflated promises.
Net metering rules drive the return
Where your utility still offers it, net metering credits the power you export, and that buyback rate is often the single biggest swing factor in your return. Several states have scaled it back, so confirm your utility's current policy.
Pairs with a sound roof
Panels last 25+ years, so install on a roof with plenty of life left. If your roof is near end-of-life, replace it first.
Local conditions
Solar in Lafayette IN
Dayton averages about 4.5 peak sun hours a day, a meaningfully better solar resource than Indiana's lake-effect north. The 30% federal residential credit (25D) expired December 31, 2025, and Indiana closed retail net metering to new customers in July 2022, so 2026 economics rest on offsetting your own usage at Duke Energy Indiana's roughly 15-cent retail rate and accepting a modest credit for exports.
Peak sun hours
~4.5/day
West-central Indiana sits south of the Lake Michigan cloud belt, so Dayton arrays out-produce comparable systems in South Bend or Elkhart over a full year.
Duke retail rate
~15¢/kWh
Every kilowatt-hour your Dayton array offsets avoids the full retail rate; after Indiana's net-metering phase-down, self-consumption is where the value concentrates.
Export credit (EDG)
Modest
New interconnections earn an excess distributed generation credit of only a few cents per kWh, so oversizing past your own load no longer pays in Dayton.
Honest 2026 economics
Two policy changes define solar math in Dayton: the federal 25D credit expired at the end of 2025 ($0 federal credit on a 2026 cash purchase), and under Indiana's SEA 309 phase-down, new Duke Energy Indiana interconnections earn an excess distributed generation (EDG) credit of roughly 125% of wholesale power cost, a few cents per kilowatt-hour, well below the retail rate you avoid by using solar power yourself. That makes right-sizing the whole game in Greater Lafayette: size to your daytime load, shift usage into solar hours, and treat exports as a small bonus. Leases and PPAs can still pass through the business 48E credit through 2027 for a lower entry price.
Permits
Rooftop solar in Dayton requires building and electrical permits plus utility interconnection approval before energizing.
FAQ
Solar questions, answered for Dayton
Is solar still worth it in Dayton without the federal credit?
It can be, with tempered expectations. A right-sized Dayton system offsetting usage at Duke's roughly 15-cent retail rate typically pays back in the 12-to-18-year range depending on how much production you consume directly. Rising rates shorten that; heavy exports lengthen it.
Does Indiana still have net metering for Dayton homeowners?
Not for new customers. Retail-rate net metering closed to new interconnections in July 2022 under SEA 309. New Dayton systems receive the EDG rate for exports, roughly 125% of the utility's wholesale cost, which is a small fraction of retail. Systems grandfathered before the cutoff keep their old terms.
Is there any federal tax credit left for Dayton solar?
Not for a homeowner cash purchase: the 30% 25D credit expired December 31, 2025 with no phase-down. Third-party leases and PPAs can still tap the business 48E credit through 2027, which is why financed offers in Dayton sometimes price below a comparable cash deal.
How should I size a system in Dayton now?
Target your actual daytime consumption rather than your total annual usage. Pairing the array with a battery or shifting big loads (EV charging, water heating, laundry) into solar hours keeps more production at retail value under the EDG framework.
Does snow hurt production much in Dayton?
Less than in northern Indiana. Greater Lafayette averages around 19 inches of snow a year, and panels typically shed it within a day or two; annual snow losses generally stay under 5%.
