Precision Engineering
for Complex Solar
We provide end-to-end commercial solar design services across structural and electrical scope—from 100-kW ballasted roofmounts to Megawatt ground mounts. Our teams produce coordinated, stamped documentation that clears plan check, satisfies the utility, and survives lender diligence.
Every discipline a C&I project needs
A commercial set gets read by a structural engineer, an electrical engineer, a utility reviewer, a lender independent engineer, and the owner's facilities team — each for a different reason. We produce cohesive plan sets that all perspectives will agree on.
Plan Sets & Construction Documents
Permit and IFC packages: site plans, array layouts, string plans, three-line diagrams, electrical calculations, racking plans, structural details, labels, and placards.
Structural Engineering
Structural review and engineering stamps in all 50 states, backed by calculation packages and structural approval letters.
Electrical Design: Solar PV, Battery & EV Charger
Electrical design engineering for Solar PV, Commercial Batteries, and Level II and III EV chargers across all US manufacturers.
Energy Modeling
Industry-leading PV energy production modeling reports with iterative layout optimization.
Interconnection Support
Interconnection application and PTO request fulfillment services for all utilities across the nation.
AHJ Permitting Services
Permit application preparation, submission, and tracking with AHJs nationwide, including plan check comment responses and revisions through approval.
How we support your project end-to-end
Five stages from first submission to a stamped, ready-to-file set — scroll to walk through each one.
Project Submission
Send us your proposed system size for an instant project quote. Once approved, we'll get started!
Design & Drafting
Your assigned multi-discipline team develops the array layout, structural approach, and electrical design, all in parallel.
Engineering Review
Licensed PE's perform Structural and Electrical review before stamping the set. We coordinate internally to avoid project delays, and return the stamped plans and approval letter with industry-leading speed.
Permit & Interconnection Submission
We prepare the AHJ package and interconnection application to each reviewer's format and submit or hand off.
AHJ & Utility
We manage plan-check comments and utility review responses through approved-for-construction.
Built for teams delivering complex projects
Whether you're a contractor adding a commercial line to a residential business or an EPC running a full development pipeline, our engineering scope flexes to fill whatever your team doesn't do in-house.
C&I Contractors
Full engineering scope for companies without in-house structural or electrical capability, and additional resource for complex or fast-turnaround projects.
Solar EPC Companies
Engineering support that keeps the project pipeline moving without bottlenecks.
Developers
Bid-stage layouts and production numbers fast enough to price a site before the deadline.
Renewable Contractors
Consistent design and permitting output that slots into your existing delivery workflow.
Solar Financiers
Precise, AHJ-compliant documentation that speeds approvals and simplifies deal closing.
Asset Owners
Independent design review and documentation for projects already in motion.
Timelines you can build a schedule on
1–3 Weeks
Fully SE + EE sealed plan sets, including all structural and electrical sheets, calculations, approval letters, and stamped drawings.
24–72 Hours
Bid-stage layouts and production estimates.
One Point of Contact, Many Teams
Assigned per client, with revision cycles tracked.
Project types we cover
From rooftop arrays to ground-mount fields, our structural and electrical scope covers the full range of commercial solar, storage, and EV charging installations.
Flat-Roof Solar PV
Ballasted or fully attached, low voltage.
Ground-Mount Solar PV
Fixed-tilt and tracker, with structural and electrical scope.
Solar Carports & Canopies
We can use manufacturer-provided plans for a complete project plan set, or provide PE stamping for site-specific installations.
Solar-Plus-Storage & Standalone Storage
AC coupled, DC coupled, or both — we design your commercial energy storage system, optimized and to code.
EV Charging
Level II and Level III EV chargers, including new and existing services and load studies.
Why EPCs and developers work with us
Six reasons EPCs and developers keep bringing us their commercial and industrial pipeline.
One Partner, All Disciplines
No coordinating across multiple consultants and hoping their drawings agree.
Bid-Stage Support
Preliminary layouts and production numbers fast enough to price and win.
Diligence-Ready Documents
Sets built to survive lender and independent-engineer review.
Scalable Capacity
Take on more projects without expanding fixed engineering overhead.
Vendor-Neutral Design
We design to your specified racking, modules, inverters, and BOS.
Complete Scope, Minus Installation
Every part of a commercial solar project except laying glass.
