One contract.
Rooftop to grid.
Engineering, permitting, interconnection, installation, and commissioning: all self-perform, under one roof, with one point of accountability.
Designed right,
before we build.
Our in-house engineering departments handle every aspect of commercial solar design — from feasibility and yield studies through stamped structural analysis and permit-ready electrical drawings.
Commercial solar is a structural and electrical problem before it's an energy problem. Every rooftop array starts with a real load analysis of the existing structure; every carport and ground mount starts with foundation design. That work is done by the same in-house structural engineers who have stamped infrastructure projects for 25 years — not outsourced to a third party.
Accurate designs from the start simplify permitting, reduce change orders, and protect your schedule.
We clear
the path.
AHJ permitting, zoning, and utility interconnection — handled in parallel with design by people who work with local authorities hundreds of times a year.
Licensed as both General Contractor and Electrical Contractor in over 250 jurisdictions, Concordia knows every local authority's quirks, timelines, and submittal requirements. We get solar projects approved faster because we've been through these counters before, everywhere.
Interconnection runs alongside permitting, not after it. Applications, utility technical screens, and agreement execution are managed so the grid connection never becomes the long pole in your schedule.
Built by our
own crews.
Self-perform racking, module, and electrical crews across the country. Commercial rooftop, carport canopies, ground mount — all installed in-house, never brokered out.
When our crews build it, our engineers designed it, and our PMs scheduled it, every team member owns the outcome. That accountability runs from the first roof penetration or pile drive to the final inverter termination.
In-house electricians and civil crews mean no markup on top of markup — one contract covers the full scope.
Every system
closed right.
Full system commissioning, utility witness testing, and monitoring activation — we don't hand off a system until it's producing.
Commissioning is where paper performance becomes real performance. Our crews verify every string, every termination, and every inverter setting against the stamped design before the utility ever shows up for the witness test.
Owners get a working monitoring platform, training on it, and a complete documentation package — not a binder of loose ends.
One team.
One outcome.
Most solar EPCs broker the work to subcontractors. We don't. Every crew on every site is Concordia.
No finger-pointing when something goes wrong. No markup on top of markup. No sub who hasn't read the engineer's intent. One accountable partner from feasibility through permission to operate.
