The best solar installers in Kentucky
A geographically balanced top picks list spanning Louisville, Lexington, and Northern Kentucky (Cincinnati metro side). Kentucky is a smaller solar market than its neighbors — there are fewer in-state residential installers, so the regional installer from Ohio is a legitimate top pick for Northern KY homeowners. For Bowling Green / Western KY, see the Honorable mentions below.
Solar Energy Solutions Local
Why listed: Lexington-headquartered residential and commercial installer — one of the longest-tenured Kentucky-HQ solar contractors. Covers KY plus neighboring states. NABCEP certified, BBB-listed, handles LG&E/KU, Duke KY, and Kentucky Power interconnection routinely.
Synergy Home Local
Why listed: Louisville-based home services company combining solar with HVAC, insulation, and whole-home efficiency. The strongest in-state pick for the Louisville metro and surrounding LG&E/KU service territory. Useful for homeowners who want a single contractor handling efficiency upgrades alongside the PV install.
ICON Solar Local
Why listed: Lexington-area residential installer with strong Northern Kentucky and Cincinnati-metro coverage — useful for homeowners on Duke Energy Kentucky in Boone, Kenton, and Campbell counties. NABCEP-certified.
Pure Power Solar Local
Why listed: Louisville-area family-owned residential installer founded 2017. Selected three years running as the Solarize Louisville campaign installer in partnership with Louisville Metro Government. Strong smaller-shop alternative to Synergy Home for Louisville-metro homeowners.
Third Sun Solar Regional
Why listed: Ohio-HQ regional installer with deep multi-state experience, operating since 2000. NABCEP certified, B Corp, and one of the longest-tenured installers in the Ohio Valley. Strong Northern and Eastern Kentucky coverage from their Ohio base.
National installers National
Sunrun, Tesla Energy, and Palmetto Solar are the major national installers still actively taking new Kentucky residential contracts as of 2026 (Kentucky has thinner national coverage than its neighbors — many national brands skip the state). Palmetto Solar currently holds EnergySage's Elite+ tier — the platform's highest installer rating. National installers typically have larger sales footprints but also higher financing markup and more variable local service quality than the state-based installers above.
Avoid — recently bankrupt or exited: Pink Energy / Power Home Solar (Chapter 7 September 2022 — caused widespread customer harm in Kentucky; do not sign with anyone claiming to honor a Pink Energy warranty without verifying the legal entity), Sunnova (Chapter 11 June 2025), the original SunPower (Chapter 11 August 2024 — the current "SunPower Inc." is rebranded Complete Solaria, a separate company), ADT Solar (exited residential solar January 2024 — warranty service only), Trinity Solar (East Coast — doesn't serve Kentucky), and Freedom Forever (Chapter 11 April 2026). If a salesperson contacts you under any of these brand names, ask which legal entity is actually signing the contract and warranty.

Other Kentucky-based installers
Southern Solar & Electrical Contracting Local
Why listed: Louisville-headquartered combined solar + electrical contractor in business since 2016. Useful third quote in the Louisville market alongside Synergy Home and Bluegrass Solar — and a strong pick for installs that need service-panel upgrades or other electrical work integrated with the PV.
Regional installers serving Kentucky
Worth a quote if you're in Northern KY (Cincinnati metro side), Eastern KY (closer to Ohio/West Virginia), or Western KY (closer to Tennessee). Expect longer drive times for service calls than a fully KY-based installer.
Bluegrass Solar Local
Why listed: Whitesburg-based residential and small commercial installer serving the Eastern KY coalfields — a region where Lexington and Louisville installers face long drives. Useful for homeowners in Letcher, Perry, and Pike counties wanting a same-region installer.
Tip: KY transitioned new residential solar customers from full net metering to Net Billing with export rates well below retail — payback math is more sensitive to system sizing and self-consumption in KY than in states with 1:1 net metering. Make sure your installer's production estimate uses your actual usage profile, not a generic "annual offset" number. Battery storage can meaningfully improve KY economics by raising self-consumption — get a bid with and without storage.
