National installers National
Sunrun, Tesla Energy, and Palmetto Solar are the major national installers still actively taking new Missouri residential contracts as of 2026. 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: 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 only, doesn't serve most states), Freedom Forever (Chapter 11 April 2026, converted to Chapter 7 liquidation August 2026), and Shine Solar (Chapter 7 March 2025 — Arkansas-based; previously held Missouri service offices, no longer operating). If a salesperson contacts you under any of these brand names, ask which legal entity is actually signing the contract and warranty.

Missouri does not have a statewide solar contractor license — verify your installer's local jurisdiction electrical license and ask for proof of general liability and workers comp insurance before signing.
