Solar Panels in Dayton, OH: 2026 Cost, AES Ohio Net Metering & Savings

Dayton and the bill

AES Ohio serves Dayton. AEP Ohio and Duke Energy Ohio are different companies even though all three operate in Ohio. Dayton's resource resembles Columbus more than Cleveland, and the utility is AES Ohio. Net metering follows AES Ohio's PUCO tariff. Do not paste an AEP rider into a Dayton bid. Roof stock is a mix of older city houses and Wright-Patterson-area suburban roofs. Base housing is not a private contract. The 2025 EIA residential average for Ohio was 16.90 cents per kWh. That statewide figure is what our calculator uses. It is not the AES Ohio tariff. A rounded solar resource for this metro is about 4.2 peak sun hours a day.

Export credits and any SREC or REC

AES Ohio sets the export credit for Dayton. AEP Ohio, the FirstEnergy companies (Toledo Edison, Ohio Edison, and The Illuminating Company), Duke Energy Ohio, and AES Ohio do not share a rider. Ohio-sited SRECs can be registered. Prices there have often been lower than in Maryland or Pennsylvania, and they still move, so no dollar figure is printed here. Ask for the current rider name and, if the bid counts credits, the contract that actually pays them.

Roofs, climate, permits, and HOAs

Ranches and modest two-stories. Many are straightforward if the roof is young. Older services may need an upgrade. A Dayton permit comes from the local building department, not from AES Ohio. An HOA can add its own review. This page does not quote a OH permit fee or an approval, because both depend on the address. Name AES Ohio. Ask which rate components are credited. Ignore a Duke Cincinnati sheet.

Estimated cost range

Estimated cost range for Dayton, labeled as an estimate and not a local quote: Berkeley Lab's August 2026 update put 2025 host-owned residential systems at about $3.60 per watt before incentives, about $3.00 per watt in the cash subset, and about $4.50 per watt in the loan subset. The median size in that set was 7.7 kW. Dayton is about 4.2 peak sun hours a day, against about 4.0 statewide. The federal residential credit under 26 U.S.C. § 25D ended for systems placed in service after December 31, 2025. The IRS treats that expenditure as made when the original installation is completed.
