Solar permit to PTO: a checklist for installers

General information for installers. Requirements vary by jurisdiction and utility. Check with your local permitting office and utility.

Last updated: October 6, 2026

The sale is the part most solar companies track well. The stretch after it, from permit to permission to operate (PTO), is where jobs sit. Nobody is sure who has the next step, a document is missing, or a correction came back and went into someone's inbox. This checklist is for the owner or ops manager who has to keep every job moving through that stretch.

The steps from signed contract to PTO

The exact order and names change by city and utility, but most residential jobs move through these steps.

  1. Site survey. Someone visits the home and records photos and notes on the roof, the electrical panel, and the site.
  2. Engineering and plan set. The system is designed and the plans are prepared for the permit application.
  3. Permit application. The plans and forms go to the local permitting office, often called the AHJ (authority having jurisdiction).
  4. Interconnection application. The utility is asked for approval to connect the system to the grid. In many areas this runs alongside the permit, not after it.
  5. Permit approval or corrections. The permitting office approves the plans or sends back corrections that have to be fixed and resubmitted.
  6. Install. The crew installs the system to the approved plans.
  7. Inspection. The local inspector checks the installed system. Some jobs need more than one inspection.
  8. Utility review. Depending on the utility, this can include its own inspection, a meter change, or a review of the final documents.
  9. PTO. The utility gives permission to operate, and the homeowner can turn the system on.

The checklist for every job

For each step above, you should be able to answer yes to these:

If a step fails any of these, that is the step where your jobs will wait.

After PTO: funding

PTO usually isn't the end of the job for the company. Funding milestones and rep commissions often depend on it. Keep funding status on the same job record as the permit and the inspection, so the office can see which jobs are funded and which are still waiting. See our guide to tracking solar funding milestones.

How Solar Nest tracks permit to PTO

Solar Nest tracks each step as a stage on one project record, from site survey and engineering through permitting, interconnection, installation, inspection, PTO and funding. Each job has an owner and a follow-up date. Site visit photos and crew comments stay on the job. Documents and signatures are attached to the record, and project chat between the office, reps, and crews stays on the job, not in a separate thread. Solar Nest tracks engineering as a step. It does not replace a 3D design tool.
