Stamped electrical design for solar and storage.
FreeSource Engineering provides electrical engineer-of-record services for commercial and industrial photovoltaic and battery energy storage projects, from early layout through permit-ready, stamped plan sets.
Start a project What we doElectrical engineering for C&I and utility-scale energy projects
Licensed PE oversight on every drawing, with designs built to pass plan check and utility review. Licensed in California, Nevada and Washington.
Solar PV design
Rooftop, carport and ground-mount systems: single-lines, string and inverter design, conductor and protection sizing.
Battery energy storage
BESS integration and interconnection design, including AC- and DC-coupled configurations and fire-code coordination.
Stamped plan sets
Permit-ready electrical drawings and calculations, sealed by a licensed professional engineer as engineer of record.
Utility-scale PV & BESS
Electrical design for utility-scale solar and battery storage, from preliminary layouts through 30% design sets.
Electrical studies
Load flow, losses, short-circuit and fault current, and arc flash studies.
Review & support
Design review, plan-check and utility comment responses, and engineering support through construction.
One engineer, accountable from first sketch to final stamp.
Every project starts by understanding what you need, and ends with engineering that delivers it. You work directly with the licensed engineer.
