Is solar worth it in Ohio?

Ohio gets limited sunshine — about 3.9 peak sun hours a day — and residential electricity runs around $0.16/kWh. For a typical $150-a-month power bill, that points to roughly a 9.9-kW system costing about $29,636 — with no federal tax credit, which ended for installations completed after December 31, 2025 — paying for itself in about 16.5 years and netting on the order of $31,728 over 25 years. Your own numbers will differ — the calculator above uses your real bill.

Ohio has modest sun and average rates, with a small SREC market. Payback is middle-of-the-road, and longer now the federal credit has ended, so accurate cost and usage numbers matter most here.

What changes the math in Ohio

• Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. Ohio sits at about $0.16.
• Sun hours — more sun means a smaller, cheaper system covers the same usage. Ohio averages ~3.9 hours.
• Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
• Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.

Ohio: the rules that actually decide your payback

Who your utility is, and why it matters

AEP Ohio, FirstEnergy (Illuminating Company, Ohio Edison, Toledo Edison), Duke Energy Ohio, and AES Ohio (Dayton) split the state — all bound by Ohio's statewide net-metering mandate, which applies regardless of when your system was installed.

What your exported power is worth

Ohio's net metering rolls excess credits forward continuously, but the export credit value under utility tariffs is modest — roughly 4-5¢/kWh on some tariffs. The structural answer is SRECs: Ohio's renewable standard sustains a certificate market paying on the order of $27 per SREC (each 1,000 kWh generated), sold separately from the metering credits.

The Ohio incentive layer

No state tax credit. The SREC income is the state-level economics: a 10 kW system generating ~13,000 kWh/yr in Ohio's ~4.2 peak-sun-hour zone mints about 13 SRECs a year — a few hundred dollars annually that belongs in any honest payback model.

Battery and self-consumption

Ohio sits in the middle: export credits are modest but SREC income is real. Self-consumption still earns the retail spread, and SRECs pay the same regardless of when you generate, so the battery decision is resilience-first here. Summer thunderstorm and winter ice-storm outages — both facts of Ohio weather — are what the storage question actually turns on. A pack that covers a well pump, a furnace fan and a fridge for a day turns a grid failure from an emergency into an inconvenience, and the SREC stream quietly helps pay for it.

What to check on a Ohio quote

• Ask whether the payback model includes SREC income at a named price, and whether the installer brokers the sale or you do it yourself through the market.
• Confirm which utility tariff's export rate the model used — 4-5¢/kWh is typical, and 'net metering' in a pitch can hide that number.
• Credits roll forward indefinitely but do not cash out; size against usage, not against the idea of banking a surplus cheque.
• Get the interconnection terms in writing: Ohio's mandate is stable, but each utility's rider has its own paperwork and timing.
