National installers National
National installer footprints in Maine are thin — ME's strong local installer ecosystem and tight Net Energy Billing rules mean most nationals don't actively market here. Sunrun and Tesla Energy take some ME contracts; Palmetto Solar currently holds EnergySage's Elite+ tier (the platform's highest installer rating) but check current ME service status before quoting. National installers typically have 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.
