How much does solar cost and save in Kentucky in 2026?

A typical 9 kW system (23 × 400 W panels) costs about $27,000 installed and produces roughly 12,391 kWh/year at 4.6 peak sun hours. At 14.27¢/kWh with net billing / reduced export credit, that is worth about $1,238 in the first year — a ~21.8-year simple payback with no federal tax credit.

Does Kentucky have net metering?

Net billing / reduced export credit. Kentucky allows utilities to credit exports at a PSC-set rate below retail for new customers.

Because exports are credited below retail, every kWh you use as it is produced is worth more than one you send to the grid. Time-of-use plans and daytime load shifting improve payback.

What solar incentives are available in Kentucky?

Federal: no credit for 2026 installs

The 30% Residential Clean Energy Credit (§25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Systems finished in 2025 are claimed on the 2025 return, and unused credit from earlier years can still carry forward. Leases and PPAs are the exception: the company that owns the system can still use the commercial §48E credit for systems placed in service by the end of 2027 and may pass some of that value to you.

Program details change often — verify on DSIRE and with your utility. Policy checked September 29, 2026.

Is solar worth it in Kentucky in 2026?

For a typical cash purchase, the math is weak: a ~21.8-year payback at average prices. Consider efficiency upgrades first, get quotes well under $3/W, size to daytime use, or compare lease/PPA offers — and treat backup power (with a battery) as the main benefit rather than savings.
