Mass Renewables

What Mass Renewables does

Mass Renewables is a privately held, family-owned solar photovoltaic (PV) installation company founded in 2009 and headquartered in Bellingham, Massachusetts, serving residential and commercial customers across six Massachusetts counties (Worcester, Middlesex, Norfolk, Plymouth, Bristol, Barnstable) and Providence County, Rhode Island. The company's core offering is the design, permitting, and installation of complete solar PV systems spanning roof-mounted arrays, ground-mounted arrays, and AllEarth dual-axis sun-tracking arrays, alongside complementary services including Tesla Powerwall battery storage (Powerwall 2, Powerwall+, and Powerwall 3), residential and commercial EV charging stations, electrical service upgrades, mini-split HVAC integration, and critter guard protection. Its product stack is differentiated by integration of partner-supplied technologies rather than internally developed hardware.

The company operates a fully in-house, no-subcontractor delivery model staffed by NABCEP-certified PV installers, OSHA-certified technicians, master electricians, and licensed builders. Founding partners Mike Kelley and Jeff Herman, business partners since 1989, continue to lead the company alongside Lead Master Electrician Nick Hurder, who formally joined the in-house team in 2015 after serving as a subcontractor since founding. Mass Renewables was selected to lead the Tesla Powerwall pilot in Massachusetts, installed the state's first Tesla Powerwall in 2016, and has accumulated over 150 verified five-star reviews on SolarReviews and an A+ BBB rating.

Revenue is generated primarily through one-time installation fees for residential and commercial solar systems and hardware sales (panels, inverters, mounting hardware, batteries, EV chargers), supplemented by a subscription-based residential solar leasing program that bundles monitoring, maintenance, and protection. The company also derives revenue from professional services including electrical upgrades, mini-split installation, and EV charger deployment. GTM is sales-led and consultative, leveraging in-home and remote (satellite-image-based) proposals, neighborhood and community referrals, and a strong presence on SolarReviews and EnergySage. Pricing is quote-based with flexible purchase and lease options, and the company participates in the Mass Save 0% Heat Loan program for battery financing.

Direct peers

• Trinity Solar: Long-established Northeast (NJ/MA/CT) residential and commercial solar installer offering roof-mount and ground-mount systems with in-house installation crews. Closest comparable peer by geography, customer mix, and range of solar services.
• ReVision Energy: Maine-based residential and commercial solar installer with in-house NABCEP-certified crews and a focus on integrated solar + battery storage systems. Comparable peer in adjacent New England geography with similar mission-driven, employee-owned positioning.
• Solar Energy World: Mid-Atlantic (Maryland) residential and commercial solar EPC with in-house installation teams and a similar focus on roof- and ground-mounted arrays plus battery storage. Comparable by business model and customer segment, though serving a different (but adjacent) geography.
• PV Squared: Vermont-headquartered residential and commercial PV installer offering grid-tied solar, off-grid systems, and battery storage. Comparable peer in terms of regional size, NABCEP-certified workforce, and similar mix of residential and light-commercial customers.
• Boston Solar: Massachusetts-based residential solar installer serving homeowners across the state with roof-mounted PV, battery storage, and EV charger offerings. Direct regional competitor to Mass Renewables for the same residential customer base in MA.

Broad incumbents

• Momentum Solar: National residential solar installer with strong Northeast (NJ-based) operations offering roof-mounted PV, battery storage, and EV charging. Competes for the same residential customer segment at substantially larger scale and broader geographic reach.
• Sunrun: Largest U.S. residential solar, battery storage, and energy services company, operating a national dealer/installer and direct-sales platform with significant Massachusetts exposure. Overlaps with Mass Renewables across residential solar and Tesla Powerwall installation, but at vastly greater scale and with proprietary financing/lease products.
• Tesla Energy: Tesla's solar + Powerwall business selling directly and via certified installers; the underlying vendor of the Powerwall hardware Mass Renewables integrates. Overlapping technology stack and customer base, though Tesla's rooftop solar operations have been repeatedly deemphasized.
