Enterprise residential teams
Built for centralized residential operations, permitting queues, and recurring multi-state workflows.
Enterprise residential solar design
Residential solar permit design for enterprise operations teams.
We support centralized and multi-state residential installers that need reliable permit throughput across jurisdictions. The value is not just a plan set. It is cleaner standards alignment, faster redline closure, and engineering that stays attached to the job through approval and field-change cycles.
Built for the national or centralized residential design and permitting teams inside installer organizations. Not intended for utility-scale EPC scope.
50-state
Licensed engineering support available nationwide for residential permit execution.
700+
Residential projects completed with permit and revision support.
Built on Sunrun management experience, later Sunrun contract work, and project workflows tied to SunPower and Sunnova.
Enterprise residential proof
This service is shaped by real enterprise residential solar experience.
Enterprise buyers want evidence that the standards, revision posture, and queue expectations were shaped inside national residential solar and reinforced through later enterprise contract work.
GBI leadership includes prior Sunrun management experience overseeing outsourced design operations for residential solar workflows.
That background did not stop with an internal role. It continued through later contract work supporting Sunrun after the management position ended.
Across that operating history, GBI leadership has worked through three enterprise contracts and project workflows tied to Sunrun, SunPower, and Sunnova.
Why enterprise teams use us
The differentiator is queue reliability, standards memory, and revision closure.
Centralized residential teams need engineering that can absorb volume, stay coherent through comments, and keep installers moving even when site conditions or reviewer expectations stop matching the clean version of the job.
We operate like an extension of the residential design queue, not a detached drafting vendor that disappears after first submittal.
Recurring partners build shared standards, reviewer history, and fewer repeated explanation cycles across states and utilities.
AHJ and utility comments stay on the same engineering thread so redline closure does not turn into a new intake every time.
National coverage matters when the real problem is jurisdiction variance, not just whether a plan set can be drafted once.
What we usually own
What the enterprise-residential workflow typically includes.
AHJ-ready residential solar plan sets and permit package drafting
PE-stamped structural and electrical sheets where required
Single-line diagrams, conductor sizing, equipment schedules, and load checks
Utility and interconnection support for residential volume programs
Revision support through permit approval and resubmittal
Re-stamp support when scope is unchanged
Field-change escalation support when site conditions diverge from the plan
Post-install production diagnostics after PTO when the project still needs engineering follow-through
How the work runs
How the work moves when we act like an embedded engineering partner.
01
Align on standards and project volume
We start with jurisdiction mix, client standards, and the real permit bottlenecks so the handoff fits how your team works.
02
Build the package for review reality
Plan sets are assembled for AHJ, utility, and installer handoff instead of stopping at a generic PDF output.
03
Carry redlines and revisions
Comments, resubmittals, and restamps stay attached to the same engineering context so cycle time does not get lost to handoffs.
04
Support field escalation when needed
If site conditions or post-install issues expose a mismatch, the engineering relationship stays live instead of resetting.
Next step
Your outsourced engineering partner should speed up permit approval, not add delays.
If your team needs permit throughput, revision coverage, and engineers who stay on the job through the real review cycle, send the project package or redline set and we will scope the viable path directly.
