Porter Ranch, CA · September – October 2023 · LADWP / LADBS
Porter Ranch: the panel was full, and one breaker fed nothing.
A dead circuit made room for the array. A solar water heater had to come off the roof first. And the association application never went in.
Three obstacles turned up on this Porter Ranch house in one site visit, and none of them was the array. The service panel was full, until an existing breaker turned out to feed nothing and could be removed. A solar thermal collector occupied the roof space the modules needed and had to come off the roof first. And the household chose to opt out of the association application rather than file it. Cali Energy took the project from site visit to permission to operate in under four weeks.

The story
This house is across the street from another project of ours, which is how it came to us. The site visit turned up three separate obstacles in one morning, and each of them is worth knowing about because they repeat on houses of this age.
The first was the service panel. It was full — every position used, no space for the solar breaker. That is normally the moment a quote grows by the price of a panel upgrade. Here it did not, because one of the breakers in it was not connected to anything. Somewhere in the history of the house a circuit had been abandoned and the breaker left in place. Removing it opened the space the array needed.
Worth saying what this is not: it is not a trick, and it is not something to assume. A breaker is removed only after the circuit behind it is confirmed dead. But it is a check worth making before anyone quotes a service upgrade, and it is not always made.
The second obstacle was on the roof. The house had a solar thermal collector — a panel that heats water rather than making electricity — sitting in the area the modules needed. It had to come off before anything could be mounted, and taking it off is water work rather than electrical: the collector is plumbed into the house's hot water system and has to be drained and disconnected on that side first. The household arranged that, the roof was clear by the middle of October, and the installation followed within the week.
It is a quietly common conflict in neighborhoods built in the era when solar water heating was the solar people bought. The roof area is finite and two generations of solar technology want the same square feet.
The third was the association, and this one went the other way from most. The household chose not to file an architectural application at all, and told us so in writing. That is their decision to make about their own property; what matters for us is that it was recorded rather than assumed, because the question of who was supposed to file what has a way of coming back a year later.
After that the project was short. The work request went in on the seventeenth of October, the installation received its final release from LADBS on the twenty-fourth, the utility completed its interconnection review the same day, and permission to operate was authorized on the twenty-fifth.
Under four weeks from a full panel and an occupied roof to a system authorized to run — and the service upgrade that first morning seemed to require was never bought.
Cali Energy designed, permitted and installed this array in Porter Ranch.

- Waited for the roof to be clear of the collector before mounting anything.
- Recorded the association opt-out in writing rather than assuming it.
- Took the project from site visit to permission to operate in under four weeks.

This installation is on the Porter Ranch projects page alongside the others, and what the work covers is set out on the Porter Ranch service area page.

Frequently asked questions
My electrical panel is full. Do I need an upgrade for solar?
Not always. Panels often carry breakers for circuits that no longer exist, and removing a confirmed dead breaker frees the space the solar circuit needs. The check costs nothing and can save a service upgrade.
Can solar panels go where a solar water heater is?
Only after the collector is removed, and that removal is water work rather than electrical: the collector is plumbed into the hot water system and has to be drained and disconnected on that side first.
Do I have to file an application with my homeowner association?
That is the owner's decision and it depends on the association's rules and on state law, which limits what an association can prohibit. What matters practically is that the choice is recorded, so that nobody is later unclear about who was supposed to file what.
How fast can a solar project go once everything is ready?
On this one the site visit and permission to operate were under four weeks apart. That happens when the panel question is answered, the roof is clear and the paperwork does not wait on anything.
Does Cali Energy install solar in Porter Ranch?
Yes. Projects here permit through LADBS and interconnect through LADWP. On houses of this generation we check the service panel and the roof for older solar equipment at the first visit.
