National installers National
Sunrun, Tesla Energy, and Palmetto Solar are the major national installers still actively taking new Massachusetts 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.
