National installers National
Sunrun, Tesla Energy, and Palmetto Solar are the major national installers still actively taking new New Hampshire 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), and Freedom Forever (Chapter 11 April 2026, converted to Chapter 7 liquidation August 2026). If a salesperson contacts you under any of these brand names, ask which legal entity is actually signing the contract and warranty.
