Are Solar Panels Worth It in Kentucky?
Last updated July 1, 2026 · based on Kentucky energy prices
In Kentucky, where residential electricity averages about 13¢/kWh and rooftop solar yields roughly 1,300 kWh per kW per year, solar has a longer payback here (about 21.0 years) because electricity is relatively cheap — it makes the most sense if your rate is rising or you value energy independence.
Kentucky solar cost & savings (typical 7 kW system)
| Metric | Estimate |
|---|---|
| Annual production | 9,100 kWh |
| Installed cost (before incentives) | $21,000 |
| Estimated annual savings | $1,001 |
| Payback period | 21.0 years |
| 25-year net savings | +$2,580 |
Figures use Kentucky average prices, a 7 kW system at $3.00/watt, 50% self-consumption at retail plus a conservative 9¢/kWh net-metering credit, and ~0.5%/yr panel degradation. Sources: EIA electricity prices and NREL PVWatts production modeling.
What this means for Kentucky homeowners in 2026
The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, so a 2026 installation in Kentucky carries the full upfront cost unless a state or utility incentive applies. Because Kentucky electricity costs relatively little, the payback case is more marginal — strongest for high electricity users, south-facing roofs, and homeowners who plan to stay long term.
Frequently asked questions
Are solar panels worth it in Kentucky in 2026?
At Kentucky's electricity price of 13¢/kWh, a typical 7 kW system saves about $1,001 per year and pays for itself in roughly 21.0 years. There is no federal solar tax credit in 2026 (Section 25D expired December 31, 2025), so these figures reflect bill savings and net metering only.
How much do solar panels cost in Kentucky?
A 7 kW system costs roughly $21,000 installed at about $3.00/watt before any state or utility incentive. Costs vary by installer, equipment, and roof complexity.
How much electricity will solar produce in Kentucky?
About 1,300 kWh per year per kW installed in Kentucky, so a 7 kW system produces roughly 9,100 kWh/year. Your exact output depends on roof orientation, tilt, and shading.
