The interconnection process runs in parallel with the permitting process. During this process, the AHJ (Authority Having Jurisdiction) verifies your array has been installed according to National Electric Code, fire code and other local standards.
In short, interconnection means your solar array is connected to the grid. Formal approval must be issued by the utility company who verifies a solar system’s compliance to its requirements.
Generally, they look for confirmation of:
- That the power exported to the grid is measurable and compliant with the grid’s standards in terms of voltage, frequency, power quality and that the equipment used is certified.
- The AC side of the PV system meetings the utility’s safety requirements.
- The power and energy generated meet the net metering program requirements.
