What Ohio Got Wrong on Solar Policy (And What's Left Standing)
Ohio once had a Solar Renewable Energy Credit (SREC) program similar to Illinois's profitable SREC structure. In 2014, the Ohio legislature froze its renewable portfolio standard under Senate Bill 310 — the first U.S. state to freeze its RPS — effectively killing the incentive for new SREC generation. Illinois went on to build a program that pays homeowners $150–$300 per SREC. Ohio homeowners got nothing comparable.
Then in 2024, the Public Utilities Commission of Ohio (PUCO) approved changes reducing AEP Ohio's net metering credit from 100% of the retail rate to approximately 87% of the retail rate for new solar customers. That means when you export excess electricity to AEP Ohio's grid, you receive 87 cents for every dollar of electricity you sell back, rather than the full retail credit.
AEP Ohio (the dominant Columbus-area utility) now credits solar exports at roughly 87% of retail. At AEP's 17.93¢/kWh rate, your exports earn approximately 15.6¢/kWh rather than the full retail rate. Self-consumption of solar power still saves you the full 17.93¢. The practical implication: right-size your system to minimize exports. Every exported kWh is worth less than every self-consumed kWh.
| Ohio Solar Incentive | Status (2026) | Notes |
|---|---|---|
| Ohio SRECs | ❌ Effectively ended | RPS frozen in 2014; no meaningful SREC market exists |
| AEP Ohio Net Metering | ⚠️ 87% of retail | Reduced from 100% for new customers in 2024 |
| Ohio Sales Tax Exemption | ✅ Active | Solar equipment exempt from Ohio 5.75% sales tax |
| Property Tax Exemption | ✅ Active (partial) | Applies to certain qualifying residential systems |
| Federal Tax Credit | ❌ Eliminated | Section 25D ended Dec 31, 2025 |
| Columbus City Programs | ⚠️ Limited | No direct rebate; some community solar through AEP Ohio |
The Ohio sales tax exemption is the most meaningful remaining incentive. On a typical $22,000 Columbus installation, the 5.75% sales tax exemption saves approximately $1,265 at point of purchase. It's not an SREC program worth $20,000+ over 15 years, but it helps.
Columbus Four-Season Solar: The Winter Production Reality
Columbus, Ohio sits at 40° north latitude — similar to Denver and Beijing — with a genuine four-season climate. This creates dramatic swings in solar production that installers here need to plan around honestly. Columbus averages 4.5 peak sun hours per day annually, but that number conceals wide seasonal variation.
Month-by-Month Production Expectations
For a 7 kW south-facing system in Columbus:
| Season / Month | Avg Daily Peak Sun Hours | Monthly Production (7kW) | Notes |
|---|---|---|---|
| January–February (winter) | 2.5–3.0 hrs | 490–590 kWh/mo | Low angle sun, frequent overcast, snow events |
| March–April (early spring) | 3.5–4.5 hrs | 690–885 kWh/mo | Rapidly improving; some cloud cover |
| May–June (late spring) | 5.0–5.8 hrs | 980–1,140 kWh/mo | Peak season begins; long days |
| July–August (summer) | 5.2–5.6 hrs | 1,020–1,100 kWh/mo | Best months; some afternoon thunderstorms |
| September–October (fall) | 4.0–4.8 hrs | 785–945 kWh/mo | Shoulder season; good output |
| November–December (late fall) | 2.8–3.3 hrs | 550–650 kWh/mo | Short days, early darkness, increased cloud cover |
The takeaway: Columbus summer production (July) runs about twice the output of winter (January). A system producing 1,050 kWh in July might produce only 520 kWh in January. Your electric bills will be significantly lower in summer and still substantial in winter — budget accordingly. Annual production for a 7 kW Columbus system runs roughly 8,400–9,000 kWh, compared to 11,000–13,000 kWh in Las Vegas with the same system.
Columbus averages 28 inches of snow annually — less than Cleveland but still meaningful. Snow accumulation can reduce production to near zero for 1–3 days after a significant storm, but panels shed snow relatively quickly as they warm up during daylight. Consider panel tilt when planning your install: steeper tilts shed snow faster. South-facing roofs at 20–30° pitch are common in Columbus's housing stock and handle snow reasonably well.
Ohio's Deregulated Electricity Market and What It Means for Columbus Solar
Ohio is a deregulated electricity state, which means residential customers in Columbus can choose their electricity generation supplier — though the distribution (delivery) side remains AEP Ohio's monopoly. This creates an opportunity and a complexity for solar owners.
AEP Ohio vs. Third-Party Suppliers
If you're currently using a third-party electricity supplier (common in Columbus — companies like IGS Energy, AEP Energy, or Constellation serve many AEP Ohio distribution customers), your bill is split between generation charges (from your supplier) and distribution/delivery charges (from AEP Ohio). Solar net metering credits appear on the AEP Ohio distribution portion of your bill. If your generation rate with a third-party supplier is lower than AEP Ohio's standard offer, your solar system effectively saves you more on the delivery/distribution components than on generation.
This matters because: if you're on a particularly cheap third-party generation contract, solar's self-consumption savings are calculated against that cheap rate — which can reduce the per-kWh value of solar slightly. Check your current total bill rate (generation + distribution + all charges) rather than just the generation rate when calculating solar savings potential.
AEP Ohio's Community Solar Program
AEP Ohio offers a community solar subscription for customers in central Ohio, including Columbus. Community solar allows you to subscribe to a share of a solar project (typically a utility-scale farm in central or western Ohio) and receive bill credits proportional to your share's production. This is the primary solar option for Columbus renters, condo owners, and homeowners with shaded or north-facing roofs.
Current community solar credits through AEP Ohio run at a rate that typically saves subscribers 5–10% on generation costs. It's not transformative, but it's low-effort and renewable.
Ohio State University's Solar Footprint and the Columbus Energy Ecosystem
Ohio State University is one of the largest campuses in the country and a significant driver of Columbus's energy and sustainability economy. OSU's solar commitments have real knock-on effects for the residential market.
OSU Campus Solar Projects
OSU has pursued ambitious solar projects as part of its commitment to carbon neutrality. The university operates solar installations across multiple facilities and has partnered with AEP Ohio on large-scale renewable procurement agreements. The OSU Solar Farm, located at the university's research farm south of Columbus, is one of the visible anchors of this commitment.
More practically: OSU's solar programs have trained hundreds of engineers, energy managers, and policy professionals who now work throughout central Ohio's solar ecosystem. Columbus has a stronger base of solar-literate professionals — from contractors to city planning staff to finance officers — than most Midwestern cities its size, partly because of OSU's continuous pipeline.
Neighborhoods with High Solar Adoption
In Columbus, the neighborhoods with the highest visible solar adoption include:
- German Village and Merion Village — older stock with south-facing slopes; historically conscious homeowners. Note that German Village has Historic District overlay requirements that may affect panel visibility.
- Clintonville — established neighborhood with bungalow and ranch homes that accept solar well; high environmental consciousness among residents
- Worthington and Dublin — northwest Columbus suburbs with newer subdivisions and higher income levels; strong solar adoption in Worthington Estates and Dublin Bridge Street district areas
- Upper Arlington — affluent westside suburb with good roofscapes; strong installer presence
- Westerville and New Albany — growing eastern suburbs with newer homes and excellent south-facing exposures
Historic District Considerations
If your home is in German Village, Victorian Village, or another Columbus historic overlay district, your solar installation may require Historic Resource Commission review. Columbus's HRC generally allows rooftop solar when panels are not visible from the primary street facing — a constraint that limits some installations but doesn't prohibit them outright. Installations visible from the street in designated historic districts require special approval and may face aesthetic requirements on panel color or frame.
Columbus Solar Costs and Honest Payback Expectations
Columbus has a solid installer ecosystem despite Ohio's policy challenges. AEP Ohio's territory serves most of the Columbus metro, though Groveport, Canal Winchester, and some outlying areas fall under different utility territories. Confirm your utility before getting quotes.
| System Size | Installed Cost | Annual Production (Columbus) | Annual Savings at 17.93¢ |
|---|---|---|---|
| 6 kW | $15,000–$19,000 | ~7,200 kWh | ~$1,291/yr |
| 8 kW | $20,000–$25,000 | ~9,600 kWh | ~$1,721/yr |
| 10 kW | $25,000–$31,000 | ~12,000 kWh | ~$2,152/yr |
Note: Annual savings estimate assumes approximately 80% self-consumption at full retail rate and 20% exported at 87% of retail (AEP Ohio's 2024 NEM structure).
At these numbers, an 8 kW system costing $22,000 (net of Ohio's sales tax exemption) achieves payback in approximately 10–12 years. This is honest — not great by national standards, but not terrible given AEP Ohio's relatively high rates (17.93¢/kWh is above the national average). The absence of SRECs is the biggest differentiator between Columbus and, say, Chicago — Chicagoans can shave 4–6 years off payback via SRECs. Columbus homeowners can't.
Columbus-area solar installers with established track records include:
- Ohio Energy Solutions — Columbus-based, strong in central Ohio residential
- Sunrise Solar Solutions — Ohio-focused installer serving Columbus metro
- Sunrun — national presence with Columbus crews; useful for lease/financing options
- Impact Energy — multi-state installer with Ohio operations
- SunPower by AEP Energy — AEP-affiliated solar offering targeting existing AEP Ohio customers
Get 3 quotes minimum. Columbus's competitive installer market means $2,000–$4,000 price variation is common for identical system specifications.
