The inspection is the moment your solar system gets the official green light. After installation, a local inspector confirms the work matches the approved plans and meets code, and then your utility grants permission to operate. For Los Angeles homeowners, understanding these final steps takes the mystery out of the home stretch — and shows why working with a licensed installer matters. This page explains what inspectors check, what PTO means, and what happens at each step.

There are usually two approvals at the end of a project. First, the local building department's inspection confirms the system is safe and built to plan. Then your utility issues permission to operate (PTO) — the final approval to energize the system and interconnect with the grid. Until PTO is granted, the system should stay off. We track both steps so nothing stalls, and we explain where your project stands at each stage.
Inspection and PTO are the last steps after design, permitting, and installation. They connect to a couple of earlier decisions: a sound roof avoids complications at attachment, and your utility interconnection or municipal utility approval is what PTO formalizes before activation.
We build to the approved plans and coordinate inspection and PTO so your system can move toward activation with clear next steps.

Inspectors typically verify the roof attachment and mounting, wiring and conduit, the inverter and electrical connections, labeling, and that the installed system matches the permitted plans. A battery, if included, has its own electrical checks.
PTO is the final approval from your utility allowing you to turn the system on and interconnect with the grid. It usually comes after the local inspection passes. Until PTO is granted, the system should not be operated.
If an inspector flags an item, your installer makes the correction and schedules a re-inspection. As your contractor, we document correction items and coordinate follow-up so the project can keep moving toward activation.
