Why this number
A kilowatt of panels in Columbus produces about 1,263 kWh a year, the highest of the 2 Ohio cities modeled here — ahead of Cleveland at 1,209. On an 8 kW system that is a payback of about 20.6 years, against 21.4 years in Cleveland, on identical hardware at the same 19.45¢/kWh.
Columbus against the rest of Ohio
Two Ohio cities have their own modeled figures, and they are only 4.5% apart — Cleveland at 1,209 kWh per kW against Columbus at 1,263, which is a remarkably narrow gap by the standards of this dataset. The rate, the export rule and the $2.69/W installed cost are identical for both; only production moves.
| Location | kWh per kW per year | 8 kW output | Annual value | Payback |
|---|---|---|---|---|
| Columbus (this page) | 1,263 | 9,094 kWh | $1,026 | 20.6 yrs |
| Cleveland | 1,209 | 8,705 kWh | $982 | 21.4 yrs |
| Ohio state average | 1,215 | 8,748 kWh | $987 | 21.3 yrs |
Against the state figure, Columbus runs 4.0% above Ohio’s 1,215 kWh per kW — a payback 0.6 years shorter than the statewide 21.3-year estimate on the same hardware at the same price.
What sets Columbus apart
AEP Ohio (Ohio Power) territory; five-point cluster around downtown.
Your utility, officially
Ohio’s average residential rate is 19.4¢/kWh, and Columbus’s AEP Ohio bills almost exactly that, at 19.33¢. These are the residential figures Columbus’s utility reported to the U.S. Energy Information Administration on Form EIA-861 for 2024 — computed as revenue ÷ sales from the official file, not estimated:
| Utility | EIA ID | Residential avg price | Residential customers | Net-metering (residential, self-reported) |
|---|---|---|---|---|
| AEP Ohio | 14006 | 19.33¢/kWh | 550,768 | 11036 customers / 78.455 MW |
How exports are treated matters as much as the headline price: AEP Ohio is modeled here under the state’s net billing rules, and that treatment is baked into every payback figure on this page.
Columbus is served by Ohio Power Co, doing business as AEP Ohio — investor-owned, and the utility behind the single most misleading-looking number on this page. The 2024 EIA-861 bundled residential average is 19.33¢/kWh, but that is a standard-service average, and in AEP Ohio’s territory standard service is the minority product: roughly 788,000 of 1.34 million households buy their generation from a third-party supplier and pay that contract instead. Ohio’s retail-choice market is not a footnote here — it is the main event. If you shop for generation, or your community runs an aggregation program, the 19.33¢ figure describes someone else’s bill. Use your own supplier rate, from your own contract, and re-run the math before you talk to an installer.
The sun side is straightforward: PVGIS models Columbus at 1,263 kWh per kW per year from a five-point cluster around downtown. That is about 4% better than Cleveland’s lake-effect-trimmed 1,209, and paired with AEP’s higher default rate — 19.33¢ against the Illuminating Company’s 16.76¢ — Columbus comes out clearly ahead of Cleveland on default-rate economics: about $244 of first-year offset per kilowatt of panels versus roughly $203 up north. Same state, same export statute, meaningfully different math.
That export statute deserves plain language. Ohio is not a full-retail net-metering state: our data classifies it as net billing under OAC 4901:1-10-28, a long-standing rule we carry at high confidence. Exports are credited under that framework rather than simply erasing retail-priced kilowatt-hours, so the exact value of your surplus depends on your tariff — get it from AEP Ohio in writing. That makes self-consumption worth more than export here, and sizing a system to your daytime load matters more than in a full-retail state.
Do not expect the state to help. Ohio has no state-level solar incentive, and — despite what many sources claim — no sales-tax exemption for solar either; our data confirms that with the Ohio Department of Taxation. There is an SREC market, and the installed-cost average is $2.69 per watt. AEP Ohio’s 2024 filing shows 11,036 residential net-metered customers and 78.455 MW, about 7.1 kW per system — a thin fleet for a territory of 1.34 million households, which is roughly what you would predict from net billing, no incentives, and a default rate most customers do not actually pay.

An 8 kW system in Columbus, priced out
| Metric | Estimate for Columbus | Ohio statewide |
|---|---|---|
| Production, unshaded 20° south | 1,263 kWh per kW/yr | 1,215 kWh per kW/yr |
| 8 kW output after a 10% roof derate | ~9,094 kWh/yr | ~8,748 kWh/yr |
| Average residential rate | 19.4¢/kWh (EIA) | 19.4¢/kWh |
| Installed cost, 8 kW | ~$21,520 at $2.69/watt | ~$21,520 |
| 2026 federal credit | $0 | $0 |
| Export rule | Net billing — exports credited below retail | Net billing — exports credited below retail |
| Export credit modeled | 5.83¢/kWh | 5.83¢/kWh |
| Annual value of that output | ~$1,026 | ~$987 |
| Rough payback (your utility) | 20.7 years | 21.3 years (state-average model) |
| 25-year net position | $5,536 | — |
Only the first two rows differ. Everything financial — rate, tariff, price per watt — is inherited from Ohio without change, which is the point: a city page that quietly used a different electricity rate from its state page would be guessing, not measuring.
Doing nothing is not free either. Twenty-five years of the electricity an 8 kW Columbus array would produce, with rates rising at 2.5% a year, comes to roughly $60,425.
If a battery is part of the plan, the battery buy vs. TPO calculator prices owning one against a lease or TPO deal.
Run it with your own bill
Shared methodology · identical on every city page
- Production figures are unshaded, south-facing, 20° PVGIS values. A real roof — its own pitch, orientation, a tree or a chimney — typically produces 10–25% less; every payback here already carries a 10% real-roof derate.
- Paybacks include $150/yr of running costs and one $2,000 inverter replacement in year 14, which is why they run longer than paybacks quoted elsewhere.
- State export rules cover investor-owned, state-regulated utilities. Municipal utilities and rural electric cooperatives are exempt in most states and set their own terms.
- Installed cost is the state-level EnergySage market figure, not a city quote; a swing of 50¢/W moves payback by roughly a year and a half either way. Get three quotes before trusting any payback — including ours.
Columbus against the rest of Ohio
Same rate, same export rule, same installed price per watt — only the sunshine changes:
| City | kWh per kW | Payback |
|---|---|---|
| Columbus | 1,263 | 20.6 years |
| Cleveland | 1,209 | 21.4 years |
A 4.5% production span across one state is the reason a single statewide number is only ever a starting point.
What Ohio pays Columbus for exported power
Ohio does not credit exports at the retail rate, and that rule reaches Columbus unchanged. The program is OAC 4901:1-10-28 , crediting surplus power at an assumed 5.8¢/kWh, about 30% of retail, because no per-kWh figure is published against a retail rate of 19.4¢.
Because a typical home uses only about 40% of its generation as it is produced, most of what a Columbus array makes is sold at that lower rate. That is why the payback above is 20.7 years and not the 11.8 years the same hardware would return under full-retail net metering. Raising self-consumption is the lever that closes the gap.
Sources and method
- Production: modeled with PVGIS v5.2 PVcalc (European Commission JRC) using the PVGIS-NSRDB radiation database — the same NREL satellite dataset PVWatts draws on for the Americas. Assumptions: 4 kWp, standard c-Si, 14% system loss, roof mounting, 20-degree tilt, due south, horizon shading on. The 1,263 kWh per kW figure for Columbus is a modeled location point, not an interpolation from the Ohio average. PVGIS is free to use with JRC attribution requested; the underlying NSRDB is public domain (NREL/DOE).
- Real-roof derate: a separate 10% deduction for azimuth, pitch and shading, applied in the shared model rather than folded into the production data — so you can adjust it if your roof is genuinely unobstructed.
- Electricity rate: U.S. Energy Information Administration, average price by state . This is Ohio’s residential average; EIA does not publish a Columbus figure, so the state rate is used and labeled as such.
- Export rules: OAC 4901:1-10-28 , from our Ohio state page and the shared export-rules dataset behind it.
- State average rate: EIA Table 5.6.A, July 2026 data (released Sep 2026), used for every state-average comparison on this page.
- Payback model: shared with the solar savings calculator and the state pages — 2.5%/yr utility inflation, 0.5%/yr degradation, $150/yr running costs, one $2,000 inverter replacement in year 14, federal credit $0. The rest of the toolset — battery, sizing, financing — is under all calculators .
- Incentives: DSIRE . City and utility programs change more often than state ones — check yours directly.
Electricity rate, export regime, production figure and installed cost on this page were last verified on 30 August 2026. Export credits reset on annual tariff cycles and incentive budgets run out mid-year, so treat every figure as a snapshot at that date and confirm current terms before acting. Nothing here is tax or financial advice.
Frequently asked questions
How much do solar panels cost in Columbus in 2026?
About $21,520 for a typical 8 kW system at $2.69 per watt, before any incentive. With the federal credit at $0 in 2026 that is close to your net cost. Note that the price per watt is a Ohio market average — there is no reliable city-level cost data, so treat it as a starting point and get three quotes.
What is the solar payback in Columbus?
Roughly 20.7 years on this model, using Columbus’s own production figure of 1,263 kWh per kW and its own utility tariff (19.33¢/kWh) with each utility’s real export treatment. That includes $150 a year of running costs and one inverter replacement, which many published paybacks leave out.
Is Columbus better or worse for solar than the rest of Ohio?
Against the state figure, Columbus runs 4.0% above Ohio’s 1,215 kWh per kW — a payback 0.6 years shorter than the statewide 21.3-year estimate on the same hardware at the same price.
Is solar worth it in Columbus in 2026?
At 19.45¢/kWh and 1,263 kWh per kW, an 8 kW system in Columbus pays back in about 20.6 years on this model. Treat that as a starting point for reading real quotes rather than as a quote: your roof’s orientation, its shading and the price you are actually offered will move it more than your city does.
How we calculated this
Year-1 saving = production (kW × the city’s modeled kWh per kW) × the blended kWh value (retail rate for self-use, the state export rule for exports). Payback = net cost ÷ year-1 saving, with the federal credit at $0 for 2026 purchases and cost per watt from the state’s installed-price band. Production is modeled from PVGIS/NSRDB irradiance for the city.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
