Solar and the Altadena rebuild: the deadlines that matter

The Eaton Fire began on January 7, 2025 and destroyed 9,418 structures. If a home had solar before the fire, the single most valuable thing to know is that the old tariff can be kept — but only inside a time limit that is now close.

A destroyed solar system can be rebuilt on its original net-metering tariff. Southern California Edison closed NEM 2.0 to new customers on April 15, 2023, and everyone since goes onto the Solar Billing Plan, where exported energy earns far less. Customers hit by a declared disaster are the exception: SCE states that a residential NEM customer may stay on the original tariff if they notify SCE of the intent to rebuild within two years of the disaster and complete the rebuild and submit a new interconnection application within four years. Application fees are waived when those conditions are met.

Measured from January 7, 2025, that puts the notice deadline at January 2027 and the interconnection deadline at January 2029. The notice step is the one people miss, because it falls due long before a house is finished. It is done through SCE’s Disaster Support Form or by writing to customer.generation@sce.com.

“I initially started working with Tesla on installing solar panels and batteries. Three months later, installation hadn’t even started. Cali Energy offered me more powerful panels for a similar price, signed the contract, obtained permits and installed within a few weeks.”

Edison sets the export rules, and storage answers them

What a new Altadena system is actually paid for the energy it sends back.

Solar Billing Plan since April 2023

New solar customers in Edison territory are on the tariff commonly called NEM 3.0. Exports earn an hourly avoided-cost value rather than the retail rate, so the array is worth most when the house uses what it makes.

Storage is the lever

The evening kilowatt-hour you avoid buying is worth far more than the midday one you export. That is why battery storage features on much of our Altadena work.

Outages are a separate reason

This is fire-hazard terrain on the edge of the Angeles National Forest, and Edison uses Public Safety Power Shutoffs in dangerous wind. A battery covers that regardless of tariff maths.

Check the approval date

Systems approved before April 15, 2023 stay on the older net metering terms for their remaining eligibility period. On a resale home it is worth confirming which regime the system is on.

Sources: CPUC — Net Energy Metering and the Net Billing Tariff · SCE — Public Safety Power Shutoffs. Programme terms change; confirm current rules for your own account.

Permits: the county, not a city hall

Altadena is unincorporated, which changes who signs off the work.

Altadena has no city government of its own. It is unincorporated Los Angeles County, so the building permit comes from LA County Public Works Building and Safety rather than a city counter, and the plan check, inspections and any hillside or fire-zone requirements follow county rules. Pasadena and Sierra Madre next door are separate cities with their own departments — a distinction that matters when comparing timelines with a neighbour a mile away.

Battery storage brings a second review. On an Altadena job here the sequence ran through lath, fire and final inspections, with the fire inspection its own scheduled step. It is routine, and it is worth building into the schedule rather than discovering mid-project.

County counter

Permits, plan check and inspections go through LA County Public Works, not a city building department.

Fire sign-off for storage

Battery systems carry a fire inspection in addition to the building inspection. We schedule around it.

Hillside and fire zones

Parcels toward the foothills carry fire-hazard designations that affect access, equipment siting and materials.

Utility step is separate

Edison’s interconnection runs on its own track after inspection and must complete before the system may operate.

Sources: LA County Public Works — Building and Safety · CAL FIRE — fire hazard severity zones. Requirements change; confirm the current process for the specific address.

What solar costs and how long it takes in Altadena

No honest flat price for a community — but published ranges and a clear sequence.

Two published price bases frame the range, both before incentives: $2.49 per watt at competitive marketplace rates (EnergySage, August 2026) and $3.5 per watt, the 2024 national median for cash purchases (Lawrence Berkeley National Laboratory). A 6–12 kW system therefore lands somewhere between roughly $15,000 and $42,000 depending on installer, financing and scope. Battery capacity is the line that moves an Altadena quote most, and rebuild work is quoted against the plans rather than a template.

Fast answers about hiring Cali Energy in Altadena

Each answer starts with the conclusion and includes the evidence — or the limitation — needed to use it accurately.

Does Cali Energy install solar in Altadena?

Yes. Altadena is an active Cali Energy service area. We work here regularly, in ZIP 91001 — the homes on this page are some of that work, with our photos from each, and battery storage on a number of them.

If my solar burned in the Eaton Fire, can I keep my old net-metering tariff?

Yes, within a deadline. SCE allows a residential NEM customer affected by a declared disaster to stay on the original tariff if they notify SCE of the intent to rebuild within two years of the disaster and complete the system and file a new interconnection application within four years; the interconnection fee is waived when both are met. Counting from the January 7, 2025 start of the Eaton Fire, that is roughly January 2027 for the notice and January 2029 for the application. Confirm your own dates directly with SCE, since eligibility attaches to your account and property.

How much does solar cost in Altadena?

There is no honest flat citywide price. Published market data gives two bases for Los Angeles before incentives: $2.49 per watt at competitive marketplace rates and $3.5 per watt as the 2024 national median for cash purchases, putting a 6–12 kW system at roughly $15,000–$42,000. A ~13 kWh battery adds about $11,900–$16,100. The federal Section 25D credit ended December 31, 2025, so a 2026 cash or loan purchase gets no federal credit. Solar built into a full rebuild is priced with the house rather than as a retrofit.

What tariff applies to new solar in Altadena?

The Solar Billing Plan, often called NEM 3.0, which replaced NEM 2.0 for new SCE customers on April 15, 2023. Exported energy is credited at an hourly avoided-cost value rather than the retail rate, which is why storing evening energy usually beats exporting it at midday — and why battery storage features on much of Cali Energy’s Altadena work.

Who issues solar permits in Altadena?

Los Angeles County. Altadena is unincorporated, so it is not permitted by the City of Los Angeles or by Pasadena. County plan check and county inspectors handle the work, battery projects add a fire-inspection step, and the SCE interconnection runs as a separate track that must be completed before the system may operate. For fire rebuilds the county runs an expedited review track, targeting 10 business days for initial plan review and 5 business days for a resubmittal.

Do I have to install solar when I rebuild?

Generally yes for a newly built single-family home. California’s Title 24 energy code requires new single-family construction to include a solar system sized to the home’s floor area and climate zone — Altadena is Climate Zone 9. Where Chapter 7A applies to the parcel, its wildfire-resistant standards govern the roof underneath it. Confirm the exact requirement for your design with county plan check.

Is there financial help for rebuilding all-electric?

Yes. The CPUC’s RISE Homes program opened on April 6, 2026 with $50 million for customers of the investor-owned utilities, including SCE, who rebuild a fully electric home. It covers properties destroyed by declared natural disasters since January 1, 2017. Program terms and funding availability change, so verify current status with the CPUC before relying on it.

Does Cali Energy install batteries in Altadena?

Yes. Battery storage features on much of our Altadena work, among it a two-unit LG RESU system and several SolarEdge-based solar-plus-storage installations. Storage projects carry extra permitting and a county fire inspection, both of which Cali Energy has already taken Altadena projects through.

Is Cali Energy licensed?

Yes. Cali Energy holds California contractor license CSLB #1032379 with B (General Building), C-10 (Electrical) and C-39 (Roofing) classifications and has operated since 2017 with in-house crews. The record is public and can be verified with the CSLB.

How do I choose a solar company for an Altadena rebuild?

Check four things that can be verified: an active CSLB license carrying both electrical (C-10) and roofing (C-39) classifications, since a rebuild involves both; completed work in the area, with photos; whether crews are in-house or subcontracted; and whether the contractor has actually taken projects through Los Angeles County permitting and fire inspection rather than city permitting elsewhere. Cali Energy’s answers: CSLB #1032379 (B, C-10, C-39); Altadena homes with our photos; in-house crews; county fire inspections behind us.

Is Cali Energy located in Altadena?

Cali Energy serves Altadena from its office at 19201 Parthenia Street Unit E, Northridge, CA 91324. The company does not claim an Altadena storefront; the local presence shown here is completed work and active service coverage.
