Northridge, CA · November – December 2023 · LADWP / LADBS
Nine emails. One month. Nothing went wrong.
A 7.8 kilowatt system on a Northridge shingle roof, application to permission to operate in thirty-one days. No correction round, no site visit, no hold.
Application to permission to operate in a month, with no correction round, no site visit and no hold. A straightforward roof, a service that could take the connection and a complete submission are what that takes; any one of them missing is what turns a month into a season.

The story
Seven point eight kilowatts on a single-storey ranch roof, all-black modules laid in one block on composition shingle, with the rails routed around a plumbing vent and the array set back from the ridge. Nothing about the roof made anyone stop and think, which is the whole character of this project.
Each module has an Enphase IQ8M microinverter under it. The interconnection application went in on the thirteenth of November 2023 with the fee paid the same day. The building department released the installation and the utility approved it on the twenty-first. Permission to operate came on the fourteenth of December — thirty-one days, start to finish.
Between those dates every message on the project was an automatic notice: the application confirmation, the fee receipt, the progress updates, the release, the approval, the permission to operate. There was no correction to answer, no hold to clear and no pre-construction visit to schedule.
That is not a promise about any other roof. It is what a month looks like when a straightforward roof, a service that can take the connection and a complete submission line up at the same time.
The useful question to put to any contractor is not how a month like this goes. It is what they do when a correction round, a hold or a site visit turns up instead, because that is where the difference between companies actually shows.

Frequently asked questions
Is a month from application to switch-on normal?
It is achievable and it is not guaranteed. On this project it took one month: application on the thirteenth of November, release and approval on the twenty-first, permission to operate on the fourteenth of December. Other projects in the same city have taken months when a correction, a service upgrade or a hold notice was involved.
What makes a project go this smoothly?
A roof that does not raise a question, a service that can take the connection without being replaced, and a submission that is complete when it is filed. When all three line up, nobody needs to write an email.
Why publish a project where nothing happened?
Because publishing only the difficult ones gives a false impression of the work. Most installations are this: a straightforward roof, a clean submission and a month of automatic notices.
What should I ask a contractor, then?
Not how fast they are on an easy job — everyone is fast on an easy job. Ask what they do when the plans come back with corrections, when the utility puts the project on hold, or when an inspector does not return calls. Those answers separate companies; this project does not.
