The best solar installers in Rhode Island
Rhode Island is small enough that the entire state is effectively two metros — Providence and Newport. Our top picks below are local installers we re-verified in October 2026 — each has a verified website or Google business listing (use the Google listing for current phone numbers and hours). For other coverage, see the Honorable mentions including a regional CT-HQ option for homeowners near the western border.

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

Tip: Most RI homeowners pick the RI Energy Growth (REG) program over standard net metering — REG pays a fixed rate for kWh produced over a 15-year contract, which usually beats avoided-cost crediting. Make sure your installer models both options against your specific load and roof.
