What E2SOL does

E2SOL (Efficient Energy Solutions, LLC) is a Providence, Rhode Island-based renewable energy design-build firm founded in 2010 that develops intelligent Net-Zero and PlusEnergy building infrastructures for commercial, industrial, government, maritime, and transportation customers. The company's core offering integrates solar power systems (roof-mounted, ground-mounted, and carport configurations supplied via its SunPower Commercial Partnership), lithium iron phosphate energy storage systems ranging from 5 kWh to 450 kWh (via Blue Planet Energy and Fortress Power partnerships), and EV charging infrastructure into turnkey project deliveries. Project teams are comprised of LEED Accredited Architects and Engineers, and the firm follows US Green Building LEED v4.1, Architecture 2030, and Zero Energy New Building Institute standards. E2SOL also operates a wholly-owned subsidiary, PowerDocks LLC, focused on marine floating photovoltaic systems and has filed three patents covering power generation devices.

E2SOL generates revenue through hardware sales (solar installations and storage systems), professional services (energy audits, feasibility studies, design, engineering, construction management, commissioning, and O&M), and PPA facilitation fees for third-party-financed projects. The go-to-market is sales-led and direct, targeting enterprise customers across diverse sectors with custom-quoted, project-specific pricing and multiple financing structures (PPA, PACE, lease, cash). The firm operates four offices across the US Northeast, Florida, and Puerto Rico and has pursued international expansion through the Smart Solar Highway platform with deployments targeted at Dubai. In January-March 2025, E2SOL signed three strategic MOUs—at CES 2025 with BK Energy (floating PV) and HOGREEN AIR (hydrogen), and in March 2025 with Yotta Energy (highway median infrastructure)—signaling an expansion from traditional commercial solar into broader clean energy infrastructure categories.

Scale indicators5 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Sunrun: Largest U.S. residential solar, battery, and EV charging installer operating a national subscription/PPA model. Comparable on solar+storage+EV bundle but at much larger scale and broader geographic footprint than E2SOL's commercial/government focus.
• Tesla Energy: Solar roof, Powerwall, and large-scale Megapack storage plus EV charging all sold as an integrated energy portfolio. Overlaps with E2SOL's solar + storage + EV charging menu but operates at vastly larger scale as a broad incumbent.
• ENGIE North America: Major utility-scale renewable IPP and EPC operating wind/solar/storage projects across North America. Overlaps in scope (C&I microgrids, EV charging infrastructure, storage) but operates with substantially greater capital, scale, and asset ownership than E2SOL.

Direct peers

• Pivot Energy: Commercial and community solar developer with in-house EPC that integrates solar + storage for C&I customers. Mirrors E2SOL's design-build model and emphasis on storage pairing plus distributed generation project finance expertise.
• Namaste Solar: Employee-owned commercial solar EPC with design-build practice covering solar, storage, and EV charging across Colorado and select Western markets. Comparable design-build commercial solar + storage + EV charging product mix.
• Borrego Solar: Commercial and utility-scale solar EPC and O&M provider offering design-build services to public, commercial, and utility buyers across the U.S. Closely comparable to E2SOL's project-based, integrated solar+storage commercial go-to-market and similar size tier before its 2021 Goldman Sachs recapitalization.
• ChargePoint: EV charging network and infrastructure provider with extensive Level 2, DC fast charger, and fleet offerings. Directly overlaps with E2SOL's EV charging infrastructure product line across transit buses, private vehicles, cargo, and electric vessels.
• DSD Renewables: Developer, EPC, and O&M provider for community solar, C&I solar, and storage projects across multiple U.S. states. Closely mirrors E2SOL's full-lifecycle development-to-O&M GTM and emphasis on integrating solar with storage solutions.
• Trinity Solar: One of the largest Northeast regional solar installers serving residential and small commercial customers in MA, RI, CT, NY, and NJ. Comparable regional concentration to E2SOL and similar reliance on state incentive structures (Smart/NEPGA/SREC) in the same geography.
• ReVision Energy: New England-based (Maine/MA/NH) solar EPC offering design, installation, and service of solar, storage, and EV charging. Highly comparable given E2SOL's Providence RI HQ and overlapping design-build + storage + EV charging product mix in the same Northeast geography.
