Solar company in Los Angeles — one utility, one permit path, thirty-four ZIP codes of our work
Yes — Cali Energy installs solar panels, battery storage, roofing and electrical upgrades across the City of Los Angeles. Our work here spans thirty-four ZIP codes, from Eagle Rock and Highland Park to Westchester, Brentwood, the Hollywood Hills and Mid-City, on systems from 1.7 kW to 16 kW. Some of those homes are shown below, with our photos from each. Everything inside the city shares two things: LADWP supplies the power and still credits exports at the retail rate, and LADBS issues the permit. What differs is the neighbourhood — heat, shade, hillside access and roof type change from one district to the next, and we keep a separate page for each area we work in most. Cali Energy is a licensed California contractor (CSLB #1032379) with a 4.9★ Google rating and in-house crews.

What is the same everywhere inside the city
Four rules that apply from San Pedro to Sylmar, and are worth knowing before you compare quotes.
NEM 3.0 does not apply
LADWP is municipal, so the CPUC’s Net Billing Tariff — what everyone calls NEM 3.0 — does not govern it. Exports inside the city are still credited against the retail rate, not an hourly avoided-cost value. Advice written for an Edison customer does not fit here.
Systems are rated in CEC-AC
LADWP sizes interconnection in CEC-AC watts rather than DC nameplate, and the two differ. One home on this page is 10.4 kW DC but 5.6 kW CEC-AC as built — the second figure is what the utility reads.
Ten kilowatts sets the timeline
Under 10 kW CEC-AC with no battery and no panel upgrade, LADWP approves in roughly 2–5 days with the meter set 1–2 weeks later. Larger systems, or any with storage or a panel upgrade, add an engineering site visit of 1–3 weeks.
Two approvals, always
LADBS issues qualifying residential solar through an online express permit, often the same day. LADWP then sets the net meter and issues the permission-to-operate email. A finished, inspected system may not legally run until that arrives.

What changes is your neighbourhood
Same utility, same permit counter — and completely different roofs. Each of these has its own page with the local detail.
Los Angeles is not one climate or one housing stock. A roof in the west Valley bakes at temperatures the coast side never sees; a lot in Sherman Oaks may be shaded by trees the city legally protects; an Encino household can run three times the electricity of an average home. None of that changes LADWP’s rules — it changes the design. These are the areas we work in most, each with the specifics that actually decide a system:
Northridge
Where our office is. Also where we cover the SGIP battery incentive, taking over abandoned installations and adding capacity to a system already running.
Woodland Hills
The hottest place ever officially recorded in the county, at 121°F. How extreme heat suppresses module output and what to do about it.
Sherman Oaks
Mature trees the city protects by ordinance, so the array is designed around shade rather than removing the oak causing it.
Encino
Large houses and large bills — one home sized against roughly 18,600 kWh a year. Plus what hillside access changes in 91436.
Granada Hills
Big lots, outbuildings and horsekeeping zoning — and the clearest explanation of the 10 kW CEC-AC approval threshold.
Chatsworth
The full range, from a 2.38 kW home system to a 567 kW commercial rooftop, plus stripping a tile roof and re-decking before the array.
West Hills
Tile roofs, a 400-amp service upgrade and the LADWP interconnection sequence explained step by step.
Canoga Park
A dated example of the fast track: LADWP application to net meter in about two weeks, and what puts a project on the slower path.
Solar work across Los Angeles
A few of the homes we have done inside the city. Street numbers stay off the page out of respect for the owners. The full photo set lives in the Los Angeles project gallery.
16 kW on forty modules
Forty high-efficiency modules on Enphase IQ8 microinverters in the hills above Hollywood — the largest array on this page, and firmly on LADWP’s standard approval path.
10.28 kW on REC and IQ8X
Premium REC modules with Enphase IQ8X microinverters, approved by LADWP — module-level conversion on a roof broken into several planes.
6.84 kW with an EV charger
Nineteen REC modules with a SolarEdge EV charger built into the inverter, designed around roughly 9,800 kWh a year — the car charges off the same equipment that runs the array.
5.41 kW with storage
Solar paired with home battery storage for backup power — bought here for resilience rather than export value, since LADWP still credits exports at retail.
Photos are ours, taken on site. Sizes are stated on the basis they were recorded on — DC nameplate or CEC-AC — because the two are not interchangeable.
A closer look at the Los Angeles jobs
What this work has in common across a very large city.
| Detail | Value | Notes |
|---|---|---|
| Homes shown here | A selection | Some of our city work, with our photos from each — what we have done inside Los Angeles goes well beyond this page |
| Spread | 34 ZIP codes | From Eagle Rock, Highland Park and El Sereno through Mid-City and Palms to Westchester, Brentwood and the Hollywood Hills |
| System sizes | 1.7–16 kW | Stated on the basis each was recorded on; the spread reflects households, not a house-shaped default |
| Utility | LADWP | Municipal on every address inside the city — retail-rate net metering throughout |
| Roof types | Shingle, flat, tile, metal | Composition shingle predominates citywide; flat roofs are common in the older and mid-century stock; tile and metal appear as well |
| Equipment we have used | REC, Q CELLS, Enphase, SolarEdge | REC 460 W modules, Q CELLS, Enphase IQ8 and IQ8X microinverters, SolarEdge inverters including one with EV charging built in |
| Battery storage | Installed | Solar-plus-storage systems for backup, since retail-rate crediting means storage here is about resilience |
| Beyond the array | Roofing | Full roof replacements paired with a new array, and an existing system removed and reinstated after a re-roof |
| Years of work | 2021–2025 | Steady work across the city throughout those years |
Four roof types, four different jobs
Across a city this size the covering varies more than anything else — and it decides the method.
Composition shingle is the citywide default and the most straightforward: flush mounting with proper flashing at every penetration. Flat and low-slope roofs — common on the mid-century and older stock — take tilt racking so modules reach a working angle, engineered for wind uplift and spaced so rows do not shade each other in winter. Tile, whether concrete, clay or S-profile, needs profile-specific hardware, a layout that follows the tile course, and replacement tiles on site because some will crack on an older roof. Metal roofs bring their own attachment methods, often clamping to the seam rather than penetrating at all.
Underneath all four sits the same question: how much life is left in the covering. A solar array is warrantied for around twenty-five years, so mounting one onto a roof with five or ten left means paying later to remove the system, redo the roof and reinstall it. We have done both sequences in the city — a full roof replacement paired with a new array, and an existing array removed and reinstated after a re-roof. Because roofing is in-house under our C-39, the assessment comes from the trade that would have to do the work.
Shingle
Flush mounting with flashed penetrations — the quickest and most common install in the city.
Flat and low-slope
Tilt racking to reach a working angle, engineered for uplift and spaced for winter sun.
Tile
Profile-specific hardware, layout from the tile course, replacement tiles carried as standard.
Metal
Seam clamps and dedicated attachments — frequently without penetrating the roof at all.
What solar costs and how long it takes in Los Angeles
No honest flat citywide price — but published ranges and one threshold that sets the schedule.
The systems we have installed inside the city run from 1.7 to 16 kW, and that spread is the honest answer: size follows consumption, roof geometry and electrical capacity. Two published price bases frame the budget, 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.
| Item | Figure | Basis |
|---|---|---|
| System sizes we have installed here | 1.7 – 16 kW | Our installations |
| Solar at marketplace rates | $2.49/W → 6 kW ≈ $14,900 · 10 kW ≈ $24,900 · 16 kW ≈ $39,800 | Market estimate — EnergySage |
| Solar at typical installer rates | $3.5/W (2024 national cash median) → 6 kW ≈ $21,000 · 16 kW ≈ $56,000 | Market estimate — LBNL 2025 Data Update |
| Battery storage (~13 kWh) | $11,864–$16,052 before incentives (average $13,958) | Market estimate — EnergySage California |
| Roof replacement with solar | Priced per job: covering, tear-off and roof geometry, quoted with the array | Scope-dependent |
| Federal tax credit | Homeowner (25D) credit ended Dec 31, 2025 — $0 on a 2026 cash or loan purchase; leased and PPA systems can still capture the 30% credit through the system owner | Official source — IRS FAQs on P.L. 119-21 |
| Time on the roof | Most residential installs: 1–3 working days; tile, tilt racking and re-roof scopes run longer | Cali Energy company figure |
| LADBS permit | Express e-permit for qualifying systems: issued online, often same day | Official process — LADBS |
| LADWP path | Under 10 kW CEC-AC without battery or panel upgrade: approval 2–5 days, meter set 1–2 weeks. Otherwise add an engineering site visit of 1–3 weeks | Official — LADWP Guide to Electric Service, p. 22 |

| Electricity | LADWP everywhere inside the city — retail-rate net metering, no CPUC net billing |
| Permitting authority | Los Angeles Department of Building and Safety (LADBS), citywide |
| Where our city work sits | Thirty-four ZIP codes, including 90065, 90045, 90049, 90068, 90064, 90026, 90041, 90032, 90046, 90016 and 90019 |
| Neighbourhoods with their own page | Northridge, Woodland Hills, Sherman Oaks, Encino, Granada Hills, Chatsworth, West Hills and Canoga Park |
| Right next door, different rules | Burbank and Glendale run their own municipal utilities; Santa Monica, Culver City, Beverly Hills and the unincorporated county areas are on Edison |
| Terrain | Hillside parcels across the Santa Monica and Verdugo ranges carry fire-hazard designations affecting access, siting and materials |
| What we verify first | Whether the address is actually inside the city, and which utility account serves it |

Reviews and verifiable trust
A public rating, a public license record and named, quotable reviews.
“Cali Energy did a great job from their proposal through installation and in the years since with follow up monitoring of our system. We have saved 1000s while contributing to lower carbon emissions.”
“I contacted Cali Energy after my inverter stopped working after about 9 years. Before them, a few other solar companies came out, but none could fix it. They diagnosed it quickly, worked with the manufacturer and got me a replacement under warranty.”
“I like that they are a local solar installation company based here in Northridge, not a sales office somewhere else.”

Fast answers about hiring Cali Energy in Los Angeles
Each answer starts with the conclusion.
Does Cali Energy install solar in Los Angeles?
Yes, across the city. Our work inside Los Angeles spans thirty-four ZIP codes and systems from 1.7 kW to 16 kW, on shingle, flat, tile and metal roofs. We also keep separate local pages for the neighbourhoods we work in most — Northridge, Woodland Hills, Sherman Oaks, Encino, Granada Hills, Chatsworth, West Hills and Canoga Park.
Who is my electricity provider in Los Angeles?
The Los Angeles Department of Water and Power, everywhere inside the city. LADWP is municipal — owned by the city rather than investor-owned — which is why its solar rules differ from Southern California Edison’s.
Does NEM 3.0 apply in Los Angeles?
No. NEM 3.0 — properly the Net Billing Tariff — is a CPUC rule for investor-owned utilities such as Edison, PG&E and SDG&E. LADWP is not governed by it, so exported energy inside the city is still credited against the retail rate. Most national advice about solar economics is written for the other kind of utility.
Why does 10 kW matter for my project?
It sets your timeline. A system under 10 kW CEC-AC with no battery and no main-panel upgrade takes LADWP’s fast track — approval in roughly 2–5 days and the meter set 1–2 weeks later. Anything larger, or with storage or a panel upgrade, follows the standard path with an engineering site visit of 1–3 weeks first.
Is the threshold in DC or CEC-AC?
CEC-AC. The two ratings are not interchangeable: one city home on this page was built as 10.4 kW DC but 5.6 kW CEC-AC. LADWP reads the CEC-AC figure, so a proposal written only in DC can misrepresent which approval path a project falls into.
Do the rules change between neighbourhoods?
The rules do not — LADWP and LADBS apply citywide. What changes is physical: summer heat is far more severe in the west Valley than near the coast, mature trees shade roofs in some areas, hillside parcels bring access and fire-hazard designations, and roof coverings vary by era and district. That is why each of our area pages covers what actually differs there.
My address says Los Angeles. Am I definitely on LADWP?
Not necessarily. A Los Angeles postal address is not proof of a City of Los Angeles parcel — neighbouring Burbank and Glendale run their own municipal utilities, and Santa Monica, Culver City, Beverly Hills and unincorporated county areas are on Edison. We verify the service address and the utility account before designing.
Do I need a battery in Los Angeles?
Not for tariff reasons. Because LADWP still credits exports at the retail rate, storage here is bought mainly for backup power rather than to rescue export value — which matters most on hillside parcels and in fire-hazard areas. Note that adding a battery moves the project onto LADWP’s longer approval path regardless of array size.
Can you replace my roof at the same time?
Yes, and we have done both sequences in the city: a full roof replacement paired with a new array, and an existing array removed and reinstated after a re-roof. If a covering has under about ten years left, replacing it first costs less than paying later to lift the system, redo the roof and reinstall everything. Roofing is in-house under our C-39.
Can I charge an electric car from the same system?
Yes. One city home on this page runs a SolarEdge inverter with the EV charger built in, on a nineteen-module REC system designed around roughly 9,800 kWh a year — one piece of equipment instead of a separate wall unit and circuit. Where a separate charger suits better, that is quoted with the electrical scope.
How long does a Los Angeles solar project take?
The roof work itself is usually 1–3 working days, longer for tile, tilt racking or a re-roof. LADBS issues qualifying residential permits online, often the same day. The variable is LADWP: fast track runs about 2–5 days to approval plus 1–2 weeks to the meter set; the standard path adds an engineering site visit of 1–3 weeks beforehand.
What does solar cost in Los Angeles?
There is no honest flat citywide price — the city is too varied. Published rates frame it: $2.49 per watt at marketplace rates and $3.5 per watt as the 2024 national cash median, putting a 6–12 kW system at roughly $15,000–$42,000 before incentives. A ~13 kWh battery adds about $11,900–$16,100. The federal 25D homeowner credit ended December 31, 2025, so a 2026 cash or loan purchase gets no federal credit. The estimate for your own home is free.
How do I check that Cali Energy is legitimate?
Compare four things rather than ad claims: (1) an active CSLB license with electrical and roofing classifications, (2) completed work in your specific area, with photos, (3) whether the company uses its own crews or subcontracts, and (4) the review pattern. Our answers: CSLB #1032379 (B, C-10, C-39); city work across thirty-four ZIP codes with our photos; in-house crews; a 4.9★ Google rating. Our office is at 19201 Parthenia St Unit E, Northridge, CA 91324 — inside the city.
