Home solar in Kentucky: prices, net metering, what is left in 2026
What Kentucky homeowners pay for solar in 2026, how the state's export rules work, and which incentives survived - verified against state sources, town by town.
Installed home solar in Kentucky compares against the U.S. marketplace average of about $2.58 a watt - roughly $30,960 for 12 kW.
The 30% federal solar credit ended December 31, 2025 - Kentucky installations completed in 2026 get $0 from it.
A home battery in Kentucky runs about $12,000-$16,000 installed, before any state storage incentive.
Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.
Kentucky rules that decide your payback
| Rule | Kentucky status |
|---|---|
| Export compensation (net metering) | Net metering must still be offered, but 2019's Senate Bill 100 replaced 1:1 retail crediting with a dollar-denominated bill credit whose rate the Kentucky PSC sets utility-by-utility in a rate case — generally well below retail — with excess credits carrying forward and never refunded in cash. |
| State incentive | No state-level incentive; utility rebates may apply |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | No exclusion on record |
Systems energized before their utility's new PSC net-metering order keep the old 1:1 kilowatt-hour credit for a full 25 years, and that grandfathering runs with the property — it survives a sale of the home — so an older solar house can be worth notably more than a new install.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Common questions
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
