KentuckySolar Incentives 2026: Tax Credits, Rebates & Net Metering

Kentucky does not offer a state income tax credit specifically for residential solar. Most homeowners rely on the 30% federal Residential Clean Energy Credit as the primary up-front incentive.

Kentucky requires investor-owned utilities to offer net metering on residential solar systems. The credit rate is the full retail electricity rate.

In practice, this means a properly sized Kentucky system can drive net annual electricity costs to within tens of dollars of zero. Top utilities operating under KY net metering rules include LG&E, KU, Duke Energy KY.

Kentucky credits exported solar at roughly ~100% of retail of the retail rate. See full Kentuckynet metering rates & rollover rules →

Solar installs in Kentucky average $2.95 per watt in 2026. A typical 8 kW system runs about $23,600 before incentives. After the 30% federal credit, the net cost drops to roughly $16,520 — the real number most KY homeowners pay.

Your price moves with system size, roof complexity, and equipment tier. Run the Kentucky savings calculator for a number matched to your actual electricity bill.

No — there is no government program handing out free solar in Kentucky. “Free solar” and “no-cost solar program” ads are leases or power purchase agreements (PPAs): a company owns the panels, claims the 30% federal credit for itself, and bills you for the power.

Buying your system — with the incentives in your name — almost always wins on lifetime savings. Read the full breakdown of “free solar” offers →

3 major utilities operate in Kentucky: LG&E, KU, Duke Energy KY. Specific rebate availability varies year to year and is typically distributed first-come, first-served until annual budget caps are reached.

Before scheduling any installation, verify current rebate status directly with your utility — programs open and close throughout the year. Most Kentucky installers will pull up-to-date rebate data during a site assessment.

Kentucky does not currently offer a property tax exemption for solar. The added home value from a solar installation is generally included in the next assessment cycle.

Kentucky does not exempt solar equipment from sales tax, so installation invoices include standard sales tax on hardware components.
