Quick Answer
Ohio uses net billing (not net metering)—exports earn only $0.04-$0.06/kWh vs. $0.12-$0.15/kWh retail. This means batteries are almost essential to capture full value. An 8 kW system costs $22,000-$29,000 with 12-16 year payback. Property tax exemption applies. Self-consumption is key—focus on using your solar directly rather than exporting.
Ohio Solar Overview
From my experience:
Ohio is one of those states where the marketing says "net metering" but the reality is net billing. It is an important distinction that catches a lot of homeowners off guard. You are exporting power for $0.04-$0.06 per kWh but paying $0.12-$0.15 to buy it back. That math is rough. If you are considering solar in Ohio, batteries become almost essential to capture the full value of your production.
Ohio's solar market is growing, but homeowners need to understand an important distinction: Ohio uses "net billing," not true "net metering." This means excess solar energy is credited at a lower rate than you pay for electricity, affecting your overall economics.
[Editor's Note, Jan 2026]:Ohio utility solar policies continue to evolve. AEP, Duke, and FirstEnergy may have different export rates and program terms. Verify current compensation structure with your specific utility before installation.

Why Ohio Is Challenging for Solar
- Net billing, not net metering: Low export compensation
- Moderate sunshine: Midwest weather reduces production
- No state tax credit: No income tax incentive
- Utility pressure: Some utilities seeking to reduce compensation further
Why Ohio Can Still Work
- Competitive costs: Installation prices reasonable
- Self-consumption value: Solar you use = full retail savings
- Battery opportunity: Store excess instead of exporting cheap
- Environmental value: Beyond just economics
Solar Costs in Ohio

Cost Per Watt
- Ohio average: $2.75-$3.50 per watt
- Columbus/Cleveland: $2.80-$3.60 per watt
- National average: $2.75-$3.50 per watt
Ohio Solar Incentives
Federal Tax Credit (2026)
- Purchased systems: The 30% residential credit (Section 25D) ended December 31, 2025
- PPA/Lease: Section 48E still provides 30% through 2027—passed to you as lower payments
- Already installed: Systems installed before 2026 still qualify
State Incentives
- State tax credit: None available
- SRECs: Ohio has an SREC program but values are very low
- Property tax exemption: Solar is generally exempt
- Sales tax: Solar equipment is taxable
Ohio SRECs
Ohio has a renewable portfolio standard that creates an SREC market, but:
- Very low values: Often only $5-$15 per SREC
- Not significant: Unlike NJ or MD markets
- Worth registering: But don't count on meaningful income
Net Billing (Not Net Metering)
This is the most important thing to understand about Ohio solar. Ohio uses "net billing" which is very different from true "net metering."
Net Billing vs. Net Metering
True Net Metering: Export 1 kWh, get credit for 1 kWh at retail rate
Ohio Net Billing: Export 1 kWh, get credit at generation rate only (~$0.04-$0.06/kWh)
This is NOT the same thing. (Source: utility tariff filings and DSIRE Database)
Ohio Net Billing: Export 1 kWh, get credit at generation rate only (~$0.04-$0.06/kWh)
This is NOT the same thing. (Source: utility tariff filings and DSIRE Database)
How Ohio Net Billing Works
- Self-consumption: Solar you use directly = full retail savings (~$0.12-$0.15/kWh)
- Exports: Excess sent to grid = generation rate credit only (~$0.04-$0.06/kWh)
- The gap: You get 1/3 to 1/2 as much for exports as for self-use
- Monetary credits: Not kWh banking—it's dollar credits
What This Means for You
- Self-consumption is key: Use solar directly for best value
- Don't oversize: Exporting earns little
- Battery storage helps: Store excess for evening use
- Longer payback: Than true net metering states
Common Misconception
Many people believe Ohio has net metering because utilities use the term. Technically, Ohio requires "net metering" but the law allows utilities to credit exports at the generation rate (avoided cost), not the full retail rate.

OH-Specific Considerations
Weather and Production
- Annual production: ~1,100-1,200 kWh per kW installed
- Lake effect: Northern Ohio can have more clouds
- Four seasons: Significant seasonal variation
- Snow: Winter production reduced
Making Solar Work in Ohio
Strategy 1: Maximize Self-Consumption
- Right-size system: Match daytime usage, don't oversize
- Shift usage: Run appliances during solar production hours
- Work from home: Daytime usage benefits most
Strategy 2: Add Battery Storage
- Store excess: Use at $0.12+ value instead of exporting at $0.05
- Evening use: Power evening loads with stored solar
- Better economics: Batteries more valuable in net billing states
Strategy 3: Consider PPA/Lease
- Lower risk: Company handles complexity
- Still has 48E credit: Through 2027
- May make sense: Given Ohio's challenging policies
Batteries Make More Sense in Ohio
In true net metering states, batteries are optional—you can "bank" energy on the grid. In Ohio, batteries let you capture full retail value instead of low export rates. Consider them seriously. (Source: utility tariff filings and DSIRE Database)
HOA Rules
- Ohio protections: Check local HOA restrictions
- Generally allowed: Most HOAs cannot prohibit solar
- Follow process: Submit to architectural review
The Bottom Line
Is Ohio Good for Solar?
Ohio is challenging but workable:
- Net billing hurts: Low export value is real drawback
- Self-consumption works: Solar you use = full value
- Battery storage helps: Capture value from excess
- Longer payback: 12-16 years typical
Best Candidates for Ohio Solar
- High daytime usage: Work from home, pool pumps
- Willing to add battery: Maximize self-consumption
- Long-term view: Accept longer payback period
- Environmental priority: Beyond just economics
Who Should Think Twice
- Expecting fast payback: Ohio's policies don't support it
- Away during day: Low self-consumption opportunity
- Won't add battery: Export value too low
- Short-term homeowner: May not see payback
Questions to Ask Installers
- What's my utility's actual export credit rate?
- How much will I self-consume vs. export?
- Does battery storage make sense for my situation?
- What's my realistic payback period?
- How does a PPA compare given Ohio's net billing?
