QE Solar

What QE Solar does

QE Solar is a US-based, privately held renewable energy operations and maintenance (O&M) provider headquartered in Springfield, New Jersey, founded in 2010. The company delivers a comprehensive lifecycle service platform for utility-scale and commercial/industrial solar PV, battery energy storage systems (BESS), and associated energy infrastructure, spanning operations and maintenance, utility and GOP (Grid Operations Provider) services, repowering, high- and medium-voltage services (via the QE MV Services / former S3 Power subsidiary), vegetation management (via the acquired Quercus team), troubleshooting and repair, aerial thermography, diagnostic testing, and certified wildfire defense and emergency response. QE Solar manages more than 8 GW of operational PV/BESS assets and has over 10 GW of PV plus 7.5 GWh of BESS under contract across 44+ states, with hundreds of engineers, electricians, and technicians supported by 24/7 NERC/CIP-compliant control rooms in Scottsdale, AZ and Springfield, NJ.

Revenue is generated primarily through recurring, subscription-style O&M contracts with asset owners, developers, investment groups, utilities, and BESS manufacturers, supplemented by project-based repower, engineering, and medium-voltage construction work and a small but differentiated emergency response offering. Proprietary, customizable reporting software sits atop a technology stack that integrates environmental and satellite data with monitoring systems to enable proactive diagnostics and prioritized issue escalation. Distribution is exclusively direct-to-enterprise via a sales-led model with dedicated portfolio managers, and the company has executed a sustained acquisition program since 2024 (S3 Power, Donahue & Sons, Doman Energy Group, Quercus Land Stewardship, and the Vanguard Energy Partners O&M division) that materially broadens its vertical scope and adds in-house engineering capacity.
