RISE, formerly known as RISE Engineering, has been Rhode Island's leading energy services company for 19 years. Based in Cranston, they have built their business on a comprehensive approach to building energy performance, with solar installation as a major component of their service portfolio.
What earned RISE the top ranking in Rhode Island was their institutional credibility and 4.6-star rating from 407 reviews. In the smallest state in the country, reputation travels fast, and RISE has maintained their standing through consistent work quality and a deep understanding of Rhode Island's energy landscape.
The company is NABCEP certified and takes advantage of Rhode Island's Renewable Energy Growth Program, which provides fixed incentive payments for solar production over a 20-year term. Their team helps homeowners navigate this program alongside the state's property and sales tax exemptions for solar.
RISE's broader energy services background means they often identify insulation, air sealing, and HVAC improvements that work alongside solar to reduce total energy costs.
With a composite score of 71.7, RISE is our top-ranked solar company in Rhode Island for 2026.

Isaksen Solar is a locally owned solar installation company headquartered in Fall River, Massachusetts, that has built a significant portion of its business serving homeowners across Rhode Island. Since its founding nine years ago, the company has carved out a strong position in the southern New England solar market by combining full in-house project execution with a level of customer service that larger regional and national competitors struggle to match.
One of Isaksen Solar's defining characteristics is that they handle every phase of a solar installation internally, from initial site assessment and system design through permitting, installation, and post-activation monitoring. They do not subcontract any portion of the work, which gives them direct control over quality and timeline at every stage. Each project is assigned a dedicated project manager who serves as a single point of contact throughout the process, a structure that reduces the communication breakdowns that frequently generate complaints in the solar industry.
The company installs residential rooftop systems, commercial arrays, ground-mount systems, and Tesla Solar Roof products. They also offer battery storage solutions for homeowners seeking backup power or greater energy independence. Their NABCEP-certified installation team works across Rhode Island's Providence, Kent, Washington, and Newport counties, as well as the Massachusetts Southcoast and Cape Cod regions. Rhode Island's strong net metering policies and the state's Renewable Energy Fund incentives make it one of the more favorable markets for residential solar in the Northeast, and Isaksen has positioned itself to help homeowners navigate those programs.
Isaksen Solar's 4.9-star Google rating across 594 reviews is among the highest in the Rhode Island market. The company also provides a proprietary monitoring app that gives customers 24/7 visibility into their system's performance, along with a guaranteed service call response time of under 72 hours. That combination of volume, rating consistency, and concrete service commitments points to an operation that has scaled its capacity without diluting the customer experience.
With a composite score of 71.4 out of 100, Isaksen Solar holds the second-ranked position among solar providers in Rhode Island for 2026.

Rooftop Power is a privately owned solar integrator headquartered in Warwick, Rhode Island, that has grown rapidly since its founding nine years ago to become one of the Northeast's most active residential and commercial solar installers. The company operates from its facility on West Natick Road in Warwick and serves customers throughout Rhode Island and into southeastern Massachusetts, positioning itself squarely in one of the country's most favorable state markets for distributed solar energy.
Like the strongest installers in the Rhode Island market, Rooftop Power handles the full project lifecycle in-house. Their team manages system design, engineering, permitting, roof work, electrical installation, and post-installation support without relying on subcontractors. This vertically integrated model gives them tighter quality control and typically shorter project timelines compared to companies that farm out portions of the work. The company also performs electrical panel upgrades, roofing repairs, and battery system installations, which means they can address common prerequisites for solar readiness without bringing in outside trades.
Rhode Island has consistently ranked among the top states for residential solar economics, thanks to generous net metering rules, the Rhode Island Renewable Energy Growth program, and relatively high retail electricity rates from National Grid. Rooftop Power's local expertise in navigating those incentive structures and utility interconnection requirements gives them an operational advantage over national brands entering the state. Their team understands the specific permitting quirks of Rhode Island municipalities and the timeline realities of National Grid's interconnection queue, knowledge that directly affects how quickly a customer's system goes live.
Rooftop Power's NABCEP-certified installation team has accumulated a 4.8-star Google rating across 816 reviews, one of the larger verified review pools in the state's solar market. That volume of feedback provides a statistically meaningful picture of customer experience, and the high average rating suggests that the company's rapid growth has not come at the expense of installation quality or communication. As with any fast-growing installer, prospective customers should verify current project timelines during the sales process.
With a composite score of 70.7 out of 100, Rooftop Power earns the third-ranked position among solar providers in Rhode Island for 2026.

*Companies displaying 15 or more years in business are typically established electrical, roofing, or general contracting firms that expanded into solar installation in more recent years. The years shown may reflect the age of the parent organization or a strategic partner, not necessarily the solar division itself. This distinction is worth considering when comparing to dedicated solar installers, as purpose-built solar companies may offer more specialized expertise despite a shorter operating history.
