The best solar installers in Rhode Island
Rhode Island is small enough that the entire state is effectively two metros — Providence and Newport. The four strongest RI-HQ residential installers are below, balanced across both. For other coverage, see the Honorable mentions including a regional CT-HQ option for homeowners near the western border.
ISM Solar Local
Why listed: East Providence-based residential and commercial installer operating since 2009 — one of the longest-tenured RI-HQ solar firms. NABCEP-certified leads with strong RI Energy REG program experience. The default Providence-metro pick.
Newport Solar Local
Why listed: Newport-based residential and small commercial installer with deep Aquidneck Island and South County experience. The right pick for homeowners in Newport, Middletown, Portsmouth, Jamestown, and the Sakonnet shore.
Sol Power Co. Local
Why listed: Pawtucket-based residential installer operating since 2009. EnergySage-screened, NABCEP-certified, with strong reviews on design quality and post-install service. A solid Providence-metro alternative to ISM Solar.
Newport Solar Local
Why listed: North Kingstown-headquartered RI residential and commercial installer operating since 2009 with 1,000+ in-state installs. Strong Newport County and South County coverage — useful for coastal RI homeowners where Providence-based installers have longer drive times. Locally owned and operated.
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). If a salesperson contacts you under any of these brand names, ask which legal entity is actually signing the contract and warranty.

Additional installers worth getting a quote from — regional installers that serve Rhode Island from neighboring states.
Regional installers serving Rhode Island
Worth a quote if you want a fifth bid or are near the CT or MA border. Expect longer drive times for service calls than a fully RI-based installer.
C-TEC Solar Regional
Why listed: CT-HQ residential and commercial installer operating since 2007 with active RI coverage. NABCEP-certified, EnergySage-screened, and experienced with the RI Energy REG program. A useful out-of-state comparison bid for Providence-metro homeowners.
Trinity Solar Regional
Why listed: Large NJ-HQ regional with 100,000+ Northeast installs and a meaningful RI presence. Caution: sales volume comes with a substantial complaint trail — get a written project timeline, a fixed cash price, and RI Energy REG program registration commitment in writing before signing.
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.
