A permit approval doesn't mean your system is live. Before it can operate, it needs utility interconnection approval and Permission to Operate (PTO) — often the slowest, most unpredictable part of a solar project. We manage this process end-to-end, so installers aren't stuck chasing utility paperwork.
We prepare and submit your utility interconnection application, matched to your specific utility's requirements and net metering program.
We track your application status, respond to utility requests, and follow up directly — so delays don't sit unnoticed in a queue.
Once your system passes inspection, we submit your Permission to Operate application, ensuring your customer can switch their system on.
