9.75 kW on a tile roof — Tarzana
A 9.75 kW system on a tile roof in Tarzana. Installed 2024. Fully permitted through LADWP with Permission to Operate granted in April 2024.
Cali Energy is a local, full-stack-licensed solar installer and battery-storage company serving Tarzana — 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 Tarzana 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 Tarzana installs, from a 2.61 kW rooftop to a 9.75 kW system.

Nine Tarzana 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 detached ADU that shares the main house's meter carries two addresses through the paperwork: LADBS permits its solar under the ADU's address, while LADWP interconnects it under the house's. On one Tarzana lot Cali Energy matched the two records by hand, had a pending meter-panel request on the same service withdrawn, and the unit's array had permission to operate in July 2026.
When a Tarzana meter panel is replaced for solar, LADWP's meter spot decides where the new one goes. On a 2022 job it named the existing location, so the new panel went in exactly where the old one stood, the utility inspected the new service on 13 August, and the meter was seated the following week.
Main panel upgrades in Tarzana →Nine systems in ZIP code 91356 report to our monitoring. When a Tarzana system we installed in 2019 underproduced in April 2025 with no error code for the manufacturer to act on, our technician was there the next day, found the fault by measuring DC voltage at the inverter, corrected it, and moved the monitoring gateway closer; production was confirmed normal nine days later.
Solar repair: how we do it →A re-roof under an old array is also the moment to decide whether that array goes back. On a Tarzana house in 2022 the older modules and their two string inverters were retired, the low-slope roof was rebuilt on new solid sheathing, and a new fifty-seven-module array went on, with permission to operate that August.
Solar removal and reinstall: how we do it →On a hipped S-tile roof in Tarzana, where no single plane could take the whole array, the modules went on in seven small groups, and every attachment reached a rafter through lifted tile, on hooks or flashed tile-replacement kits, with each tile reset over it; the final passed in December 2022.
Roofing: how we do it →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.
