Future Energy Solar

WoburnLocation

Future Energy Solar has been serving southern New Hampshire and the Merrimack Valley from their Massachusetts base for 11 years. In a state where electricity costs are among the highest in the country and net metering provides strong economic incentives for solar, Future Energy has positioned themselves as a company that helps homeowners make sense of the numbers. What earned Future Energy Solar the top ranking in New Hampshire was their 4.9-star rating from 114 reviews and their focused approach to customer education. New Hampshire's solar incentive landscape is less generous than neighboring Massachusetts, which means the sales conversation is different. Future Energy's team is honest about payback timelines and does not oversell, which reviewers consistently appreciate. The company is NABCEP certified and works with the permitting requirements of New Hampshire's various municipalities, which can vary significantly from one town to the next. Their experience with Eversource and Liberty Utilities interconnection processes streamlines installation timelines. With a composite score of 78.2, Future Energy Solar is our top-ranked solar company in New Hampshire for 2026.

ReVision Energy

BrentwoodLocation

ReVision Energy is one of the most established and mission-driven solar companies operating in New England, with 20 years of experience and a Brentwood, New Hampshire headquarters that anchors their operations across the state. The company is structured as an employee-owned cooperative and holds B Corporation certification, a designation that reflects a verified commitment to social and environmental performance standards that go beyond the typical solar installer's marketing claims. The scale of ReVision Energy's operation sets them apart from most regional competitors. With more than 400 employee-owners spread across offices in Maine, New Hampshire, Massachusetts, and Vermont, they have the infrastructure to handle projects ranging from modest residential rooftop systems to large commercial and institutional installations. Their Brentwood facility includes a showroom, design offices, and a 7,000-square-foot warehouse that supports their installation teams. Solar Power World has ranked ReVision as the number one rooftop solar installer in New England for five consecutive years, a distinction that reflects both volume and consistency. Their NABCEP-certified installation crews work across solar electric, solar heat pump, and EV charger installations, giving homeowners access to a broader energy transition toolkit than most single-service solar firms can offer. The company's 4.8-star Google rating across 194 reviews demonstrates solid customer satisfaction, with particular praise for system design quality, project management communication, and post-installation support. The employee-ownership structure is worth noting because it tends to produce different incentive alignment than privately held or venture-backed solar companies. When the installation crew and the design team have a direct financial stake in long-term customer satisfaction and company reputation, the pressure to cut corners or oversell system capacity is meaningfully reduced. That structural advantage does not guarantee a perfect experience for every customer, but it creates a framework where quality tends to be prioritized over speed. ReVision Energy earns a composite score of 73.1 out of 100, securing the number two ranking among New Hampshire solar installers for 2026.

Granite State Solar

0BBB Complaints
18*Years in Business
BowLocation

Granite State Solar has been a dedicated New Hampshire installer for 18 years, operating from their base in Bow to serve homeowners across the Granite State. In a market where national chains and out-of-state companies periodically enter and exit, the company's nearly two-decade commitment to a single state gives them an intimate familiarity with New Hampshire's permitting landscape, utility interconnection requirements, and the specific incentive programs that make solar economics work for local homeowners. The company has earned consistent recognition within the state, including being voted Best of Business for solar for close to a decade and winning the Best of the 603 award every year the competition has been held from 2021 through 2024. These are community-driven honors rather than pay-to-play industry awards, which makes them a more reliable signal of genuine local reputation. Their 4.8-star Google rating across 223 reviews reinforces that picture, with customers regularly citing professionalism, system design quality, and a smooth installation experience from initial quote through final commissioning. Granite State Solar focuses on both residential solar panel systems and backup power solutions, a combination that has become increasingly relevant as New Hampshire homeowners seek resilience against winter storms and occasional grid instability. Their installation teams handle the full project lifecycle in-house, from site assessment and design through permitting, installation, and utility interconnection, avoiding the subcontractor handoffs that can introduce quality control gaps. Some customer feedback has flagged occasional delays in post-installation service visits, a pattern that is not uncommon among successful regional installers whose growth sometimes outpaces their service department staffing. For homeowners considering Granite State Solar, it is worth asking about current service response timelines during the sales process. That caveat aside, the company's track record of repeat business and community recognition speaks to a level of operational consistency that is difficult to manufacture. Granite State Solar earns a composite score of 73.1 out of 100, placing them at number three among New Hampshire solar installers 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.
