Complete Guide to Solar Energy in Ohio
Your complete resource for solar energy. Everything you need to know about solar laws, solar costs, solar financing, and solar installation in Ohio.
Why Ohio is Excellent for Solar Energy
Reliable Solar Potential
Ohio averages about 173 sunny days per year, which is enough to support strong residential solar production when systems are properly sized and installed. While Ohio is not one of the sunniest states, modern rooftop systems still perform well across much of the state.
Strong Savings Potential
As of March 2026, the average installed solar cost in Ohio is about $2.74 per watt, with EnergySage estimating an average 12.59-year payback and roughly $48,573 in 25-year savings. With January 2026 residential electricity prices at 17.59¢/kWh, Ohio solar economics are stronger than many homeowners expect.
One of the Midwest’s Largest Solar Markets
Ohio already has [6,339 MWdc of installed solar], enough to power [776,993 homes], along with [8,179 solar jobs], [253 solar companies], and $8.8 billion in total solar investment. That makes Ohio one of the more substantial solar markets in the Midwest, with deep installer and supply-chain activity.
Statewide Net Metering and Solar Access Rules
Ohio’s statewide net metering rules allow eligible customer-generators to size systems to offset up to 120% of their own electricity needs. Ohio also recognizes formal solar access easements under Ohio Revised Code 5301.63, and state law provides protections for solar installations in planned communities and certain condominium properties.

Laws & Regulations
Ohio homeowners should understand the state’s net metering rules through PUCO, solar access easements under ORC 5301.63, and additional protections for solar panels in planned communities and some condominium properties. These legal protections make Ohio more solar-friendly than many people realize.
Residential Solar
Complete guide for Ohio homeowners covering system sizing, roof suitability, installer comparison, equipment selection, and the way statewide net metering plus local utility implementation affects actual bill savings. Ohio’s average bill-covering system is relatively large, so accurate sizing matters.
Costs & Savings
As of 2026, the average Ohio solar system costs about $2.74/W, and the average system size needed to cover the typical electric bill is 13.89 kW. EnergySage estimates an average 12.59-year payback and $48,573 in lifetime savings over 25 years.
Financing Options
Ohio’s financing picture is stronger than in many neighboring states because homeowners can combine utility-bill savings with SREC income and programs such as the Energy Conservation for Ohioans (ECO-Link) reduced-rate loan program. Cash purchase, loans, leases, and PPAs can all work, but project economics should still be modeled against local utility rules.
Installation Guide
Before installing solar in Ohio, homeowners should confirm local permitting, interconnection requirements, and meter requirements with the serving utility. AEP Ohio says most homeowner interconnection requests are completed in under 35 days when applications are complete, and utilities generally require bi-directional or advanced metering for net metering service.
Solar 101
Learn how net metering works in Ohio, how exported electricity is credited, why system size is usually capped to your own usage profile, and how SRECs can add modest extra value to a residential project. In Ohio, solar economics are built on a combination of self-consumption, bill credits, and marketable clean-energy attributes.
Community Solar
Ohio’s investor-owned utilities generally follow statewide PUCO net metering rules, but each utility still applies its own interconnection paperwork and tariff structure. AEP Ohio says its NEMS tariff determines the rate credited for excess energy and that monthly excess generation becomes a bill credit carried into future bills. FirstEnergy’s Ohio net metering rider application shows similar eligibility concepts for Ohio Edison, Toledo Edison, and The Illuminating Company, including qualifying renewable technologies, on-site generation, and bi-directional metering. Duke Energy Ohio also allows customers to apply to safely connect self-generation to the grid.

Important 2026 Updates
The Federal Residential Credit Has Ended
The IRS Form 5695 instructions say homeowners cannot claim the residential clean energy credit for expenditures made after December 31, 2025. In Ohio, that makes net metering, SRECs, financing, and electricity-rate avoidance more important than before.
Ohio Still Has Strong State-Level Project Economics
Even after the federal residential credit ended, Ohio remains one of the stronger Midwest markets for homeowners because of statewide net metering, continuing SREC value through January 2028, and favorable project treatment such as Ohio’s qualified energy property tax exemption for projects 250 kW or less.
Ohio Solar Laws & Regulations
Ohio’s solar-access framework starts with Ohio Revised Code 5301.63, which allows property owners to create formal solar access easements in writing. Those easements can define the burdened and benefited properties, permissible development limits, termination terms, and legal remedies if access to sunlight is obstructed.
For homeowners in associations, Ohio also has meaningful statutory protection. In planned communities, owners may install solar energy collection devices unless the declaration specifically prohibits them, although associations may still impose reasonable restrictions on size, placement, and manner. In certain condominium properties, owners of “solar appropriate units” receive similar rights, again subject to reasonable restrictions and declaration terms.
Ohio’s statewide net metering rules are administered by PUCO. Eligible systems must be intended primarily to offset the customer’s own electricity requirements, up to 120% of annual usage, and credits can carry forward continuously on future bills while service remains at the same premises. However, only the energy portion is credited, not transmission or distribution charges, and rural cooperatives and municipal utilities are not required to offer net metering.
On taxes, Ohio does offer favorable treatment for many projects, but not in the same simple “broad homeowner sales-tax holiday” format seen in some states. The most relevant clean rule for small solar systems is Ohio’s qualified energy project/property tax exemption, under which projects below 250 kW are exempt as a matter of law.
