National installers National
Sunrun, Tesla Energy, and Palmetto Solar are the major national installers still actively taking new 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), 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 Colorado-based installers

Why listed: 25+ year track record, off-grid + grid-tied specialist. Note: former SunPower Elite dealer (verify post-SunPower-bankruptcy equipment sourcing before signing).
Colorado Solar Technologies Local
Why listed: EnergySage-listed CO installer.
Regional installers serving Colorado

Tip: Colorado has multiple utility rebate programs stacked on top of net metering — Xcel Solar Rewards production incentive, Holy Cross Energy rebate, City of Boulder, and Pueblo program. The right installer documents which incentives you qualify for at PTO and files the paperwork on your behalf. If a Colorado bid doesn't list specific utility rebates by name, ask why.
