Complete Guide to Solar Energy in Kentucky
Your complete resource for solar energy. Everything you need to know about solar laws, solar costs, solar financing, and solar installation in Kentucky.
Why Kentucky is Excellent for Solar Energy
Reliable Solar Potential
Kentucky receives 189 sunny days per year, which gives homeowners enough solar exposure to make rooftop solar practical across much of the state. Even with humid summers and variable seasonal weather, Kentucky still offers solid year-round production for properly designed residential systems.
Rising Electricity Costs
Residential electricity prices in Kentucky reached 14.27¢/kWh, making solar more attractive for homeowners looking to control long-term energy costs. As utility bills rise, locking in more of your own power production can provide meaningful savings over the life of the system.
Strong Utility-Based Net Metering in Key Service Areas
Kentucky does not offer broad statewide residential solar tax incentives, but net metering remains an important part of the value equation. LG&E and KU still offer full retail net metering, while Duke Energy Kentucky moved new customers to an avoided-cost structure starting in 2025, with earlier customers grandfathered for 25 years. That makes utility territory especially important when evaluating savings.
Growing State Solar Market
Kentucky’s solar market has expanded rapidly, with 1,707 MWdc installed, enough to power 174,375 homes. The state now supports 1,724 solar jobs and 50 solar companies, giving homeowners a stronger installer base and more market experience than in earlier years.

Important 2026 Updates
Federal Residential Solar Credit Has Ended
The Residential Clean Energy Credit is no longer available for expenditures made after December 31, 2025. For Kentucky homeowners, that means new residential solar projects in 2026 need to be evaluated based on utility savings, financing, and local net metering value rather than the former federal 30% credit.
Kentucky Net Metering Depends More on Utility Territory
Kentucky’s solar economics now vary more by utility. LG&E and KU continue to offer full retail net metering, while Duke Energy Kentucky shifted new customers to a lower avoided-cost credit structure in 2025. Rural co-ops and municipal or TVA-served utilities can follow different rules, so homeowners should check local policy before sizing a system.
Kentucky Solar Laws & Regulations
Utility Rules Drive Solar Value
Kentucky’s residential solar market is shaped more by utility regulation than by state tax incentives. The federal residential credit has expired for new post-2025 projects, so system value now depends more heavily on electricity savings, utility crediting rules, and system design.
Solar Easements & HOA Review
Kentucky law recognizes solar easements, allowing property owners to create written agreements that protect access to sunlight for solar energy systems. Unlike some states, Kentucky does not have a strong statewide HOA solar-rights statute, so homeowners should review association rules carefully before installation.
Net Metering by Utility
Kentucky also requires certain investor-owned utilities and electric cooperatives to offer net metering, while TVA utilities are exempt from that statewide requirement. Current interconnection and net metering policy is overseen by the Kentucky Public Service Commission, and compensation terms can differ significantly between utility territories.
