A Commercial Solar EPC Built for Serious Buildings
Ferrius Energy is a commercial solar EPC headquartered in Saugus, Massachusetts. We engineer, procure, and build commercial solar systems, utility-scale solar farms, and battery storage for hotels, condominiums, supermarkets, industrial facilities, and investors across eight U.S. states.
Everything is delivered in-house, under one roof, with our own licensed crews.
One accountable team, from design to O&M
Most commercial solar projects pass through a chain of subcontractors, where design, permitting, construction, and maintenance each sit with a different company.
Ferrius Energy was built to remove that friction. Our in-house team handles engineering, procurement, and construction as a single EPC contract, so there are no subcontractor chains, no scope drift, and one point of accountability for the life of the system.
