East Los Angeles, CA · March – September 2022 · Southern California Edison / LA County

East Los Angeles: the final was turned back over the color of a label.

The array was up, the battery was in, the fire inspection was booked. The job stopped on a placard.

Written by the Cali Energy project team · California contractor license 1032379 · Updated September 2026

A photovoltaic system carries warning labels at its disconnects, along its conduit and at the point of connection, and the rules cover more than the wording: color and contrast, durability, and where each label goes are all specified, and an inspector checks them as an item like any other. On this East Los Angeles project — unincorporated county, so county building, county fire and Southern California Edison rather than the city agencies — the final had to be rescheduled because the placards were the wrong color. Cali Energy replaced them and the permit passed two weeks later.

The story

The array went up on a Monday in March, along with a battery and the sub panel it needed. By the following Thursday the final was booked for the first of April, and the project looked finished.

Two things then happened in the same week, and both are worth knowing about before they happen to you.

The first: a fire inspection was required before the building final. Not after it, not alongside it — before. That is a jurisdiction question rather than a solar question, and it is one people get wrong because of where this address sits.

East Los Angeles is not part of the City of Los Angeles. It is unincorporated county territory, which means the county building department issues the permit, county fire runs the fire inspection, and the electricity comes from Southern California Edison and not from LADWP. Everything an owner has read about LADBS timelines and LADWP interconnection applies to an address a few miles west and not to this one.

The second thing: the final was rescheduled, and the reason was the placards.

Not missing placards. Wrong color.

This is the part that sounds like bureaucracy and is not. A solar installation is labeled so that somebody who did not build it can understand it quickly and under pressure. A firefighter on a roof at night needs to know that conductors between the array and the disconnect stay live even after the main breaker is off. An electrician opening a panel four owners later needs to know there is a second source of supply behind it.

So the labeling rules cover what a label has to survive and how it has to read, not only what it says. Specified color and contrast, so it is recognizable before it is legible. Weather and ultraviolet resistance, because a placard that fades to nothing in three summers has failed at its job. Placement at every point where somebody might act on the wrong assumption: the disconnects, the conduit runs, the service equipment, the point of connection.

An inspector treats a label of the wrong color the way they would treat no label at all, because in the situation the label exists for, it will not be read as a warning.

New placards went on, the fire inspection was held on the eighth of April, and the final passed on the fifteenth.

One more thing belongs to the same week. At the point the inspections were being cleared, the microinverters were reporting but the gateway and the battery had not been commissioned, and the monitoring account was still being straightened out. Passing a final and having a system in service are different events, and they do not always arrive in the order an owner expects.

In September the household reported a single module not producing. The manufacturer read it as the connection between that module and its microinverter, and a technician went out.

Cali Energy installed, finaled and serviced this system in East Los Angeles.

How it ran

Two weeks between the fire inspection and the final, on a system that was otherwise finished.

What we did

• Scoped the battery and the sub panel alongside the array rather than after it.
• Booked the fire inspection ahead of the building final once it was clear one was required.
• Replaced the placards to specification and rebooked rather than arguing the point.
• Attended in September when a single module stopped producing.

System specifications

Is your project like this one?

• Your final was rescheduled and the reason sounded trivial.
• You have been told your solar labels are wrong.
• Your address is in an unincorporated area and you assumed the city rules applied.
• Your system has passed its final and is still not reporting properly.

Frequently asked questions

Why do solar systems need warning labels?

So that somebody who did not build the system can understand it quickly and under pressure. Conductors between the array and the disconnect stay live with the main breaker off, and anyone opening equipment years later needs to know there is a second source of supply behind it.

Can the wrong color placard fail an inspection?

Yes. The specification covers color and contrast, weather and ultraviolet resistance and placement, not only the wording. A label of the wrong color is treated as no label, because in the situation it exists for it will not be read as a warning.

Is East Los Angeles part of the City of Los Angeles?

No. It is unincorporated Los Angeles County, so the county building department issues the permit, county fire handles the fire inspection, and the electricity is supplied by Southern California Edison rather than LADWP. Advice written for the city does not transfer to this address.

Does a solar project need a separate fire inspection?

In some jurisdictions yes, as its own step before the building final rather than part of it. On this project the fire inspection had to be held first, which changes the order of the calendar and is worth confirming at the start rather than the end.

Does Cali Energy install solar in East Los Angeles?

Yes, including systems with a battery and a sub panel. Because this is unincorporated county rather than the city, the permit, the fire inspection and the interconnection all run through different agencies than a Los Angeles address a few miles west, and the sequence has to be set up for that from the beginning.
