Net metering, tax credits and incentives in 2026
Kentucky pays less than retail for exported solar power. Under Net metering service (NMS-2), power you send to the grid earns about 7.3¢/kWh, against 14.3¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 10.1¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
LG&E and KU credit exports at about 7.1¢ and 7.5¢ per kWh (March 2026 Kentucky PSC orders); other Kentucky utilities set their own rates. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
Kentucky and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Kentucky and ask installers which programs they apply for you.
