THE WORKFLOW

How we fit into your process.

From engineering to permit approval, we handle it all. Stamped plans, AHJ submissions, corrections, and follow-through.

01
You land the job
Close the deal. We handle the engineering paperwork. You focus on what you do best: Selling and installing.
02
Send us the project brief
Utility bill, roof photos or aerial, AHJ info, and target size. A one-page intake form or a quick email. Whichever fits your workflow.
03
We design and stamp
Your dedicated project engineer runs the layout, calcs, and permit drawings. You see a draft before we finalize anything.
04
Permit-ready in a week
The full stamped package lands in your inbox, ready to submit. Your name on the front sheet. Our PE stamp inside.
05
We stay on through PTO
Comments? RFIs? Inspection questions? We're reachable throughout the project, not just until we send the drawings.
Workflow
ENGINEERED BY SONORA SOLAR
Every plan set is designed, calculated, and stamped in-house by our licensed engineers - and it shows on the paperwork.
THAT'S IT — FIVE STEPS FROM SIGNED CONTRACT TO PERMIT-READY PLANS.

contractor faq

Questions we hear from new partners

Do you put my company's name on the plans?

We list Sonora Solar Engineering as the engineer of record on all deliverables, as required. Our focus is the engineering: Accurate designs, code-compliant calculations, and a stamp AHJs trust, so your submittal moves through review without friction.

What do you need from me to get started?

Just the basics: a copy of the utility bill, roof or site photos, the AHJ's jurisdiction, and your target system size. Send those over and our engineers take it from there.

How long does it take to get stamped plans back?

Most projects come back permit-ready within a week of us receiving your project brief. Larger or more complex jobs may take a bit longer — we'll flag that upfront.

What if the AHJ requests revisions?

We handle comment responses directly — included in the original project price. If a revision requires new engineering (change of scope), we'll quote the additional work before proceeding. Our 90%+ first-cycle rate means revisions are the exception, not the rule.

Can you work in States where I'm bidding new work?

Yes. Our engineers hold — or can obtain — PE licensure across all 50 states, so wherever you're bidding, we can stamp for that jurisdiction. Just flag the state and AHJ in your project brief and we'll take it from there.
