9.9 kW rooftop solar — Porter Ranch
A 9.9 kW system in Porter Ranch. Installed 2022. Clean, low-profile panel layout that follows the roof lines.
Cali Energy is a local, full-stack-licensed solar installer and battery-storage company serving Porter Ranch — part of the City of Los Angeles served by LADWP. Because LADWP isn't on the CPUC's NEM 3.0 tariff, net metering in Porter Ranch stays more favorable than in neighboring SCE areas, so paybacks remain strong. We're based in Northridge and do every step in-house — solar panels, battery backup, roofing and electrical — under one CSLB license (#1032379: B, C-10, C-39). Below are real Porter Ranch installs, from a 2.32 kW rooftop to a 9.9 kW system.

Thirteen Porter Ranch case studies go further than the photographs above — what the roof was, what the service took, how the permit and the interconnection actually ran, and what happened after the system was switched on.
A Porter Ranch address can show up in utility records as Porter Ranch, Northridge or Los Angeles, because the neighborhood is inside Los Angeles city limits and shares ZIP code 91326 with Northridge; LADBS issues the permits and LADWP connects the systems. On a 2022 job whose interconnection paperwork named two different cities, Cali Energy carried a thirty-nine-module, 14.4 kW array from plan check to permission to operate in twelve weeks, and the system was switched on in September.
On three Porter Ranch jobs the main panel could not take a solar breaker as it was, and each got its own answer. A breaker that fed nothing came out to free a space, and that house had permission to operate under four weeks after the site visit; on another, the household circuits moved to a 200-amp sub panel, leaving the main with only the service and the solar; and where the roof could take thirty-four modules but the panel nine, the household chose nine over a 225-amp upgrade and was switched on in December 2025.
Main panel upgrades in Porter Ranch →ZIP code 91326 has more systems on our monitoring than any other place we serve: twenty-six, and eleven have been running for over five years. On one of them, two years after installation, a single microinverter was replaced under warranty while the rest of the array kept producing.
Solar repair in Porter Ranch →The chimney flashing on a Porter Ranch tile roof needed replacing, so in late 2023 we renewed it, taking up about 400 square feet of tile, before a single module went on; the system's meter was set on 16 December.
Roofing in Porter Ranch →One licensed contractor covers solar, battery, roofing and electrical, so the job does not get handed between companies.
Based in Northridge, we know LADWP permitting and net metering inside out.
