Solar panels in Pasadena
Pasadena is not on Edison. The city runs its own electric utility — Pasadena Water and Power — so the CPUC's NEM 3.0 decision that cut export credits for SCE customers has no force on your roof. PWP writes its own solar rules, credits your exports on its own formula, and in 2026 is paying rooftop solar rebates that most of California no longer has. Collective Solar is based in Northridge and serves Pasadena. We design to PWP's rules, not to a statewide template.
Why Pasadena solar math is different from the rest of LA County
Pasadena has owned its electric department since 1906, and today Pasadena Water and Power delivers electricity to more than 65,000 customers inside the city. Because it is municipal, it sits outside CPUC jurisdiction. Every quote you read online about NEM 3.0 slashing the value of exported solar was written about Edison, PG&E and SDG&E customers. None of it governs a Pasadena address.
PWP's program is Net Surplus Compensation, also written as net energy metering, set out in Pasadena Municipal Code 13.04.177. Power you send to the grid comes back as a credit on your electric bill, and you pick how it settles. Under annual reconciliation you are billed once a year and net surplus is paid at PWP's average energy charge for that year plus 2.5 cents per kWh for the renewable attributes. Under monthly or bi-monthly settlement, surplus earns the energy charge plus the same 2.5 cents plus a further 6.6 cents per kWh. The higher rate is not automatically the better deal: settling once a year lets a strong summer bank against a weak winter, while settling monthly cashes out more often at a better price. Which one wins depends on how seasonal your production runs against your usage, so we pull twelve months of your PWP bills and model both before recommending a system size.
The other half of the 2026 picture is money on the table. The federal residential solar tax credit ended December 31, 2025 — details in our 2026 tax credit guide — and nothing local fully replaces it. What Pasadena does have is its own money on the table, which most of California does not. On April 7, 2026 PWP opened a solar and battery rebate pilot: $0.60 per watt for a new or expanded residential rooftop system, $1.00 per watt for customers enrolled in PWP's income-qualified bill assistance programs, and up to $550 per kWh for battery storage. The conditions matter as much as the numbers. The system has to be installed on or after January 1, 2026; it has to be customer-owned, so leased and PPA systems are excluded; PWP requires the work to be done by a licensed contractor, so we scope that into the project rather than leaving it to you to sort out; there is a lifetime cap of one rebate per residential service address; and the completed application has to reach PWP within 180 days of interconnection. PWP is waiving its own plan review and inspection fees during the pilot, and says plainly that program funds are limited and terms can change — so we confirm what is actually still open before any of it goes in your estimate. If a zero-down structure suits you better than owning, our lease-vs-buy guide walks the trade-off, and giving up this rebate is part of it.
Craftsman bungalows, Hastings Ranch tracts, foothill rebuilds
Pasadena's roofs are older than almost anywhere we work. The city's landmark districts — Bungalow Heaven, Garfield Heights, Normandie Heights, Washington Square — are named for early-1900s neighborhoods built around Craftsman bungalows, with period revival houses and their heavier tile filling in around them. Upper Hastings Ranch reads as postwar tract. Linda Vista and the San Rafael hills run to one-off hillside houses where the roof breaks into several planes and the slope behind the house takes the late afternoon. No single layout covers that spread, so the array gets drawn from a shade study of your specific roof rather than off a template.
On a house this old the first honest question is not the array, it is what sits under it. A Pasadena roof that has already been through a couple of recoats can look sound from the driveway and still be near the end of its deck life, and pulling an array off and putting it back is the most expensive way to find that out. So we call it up front: if a reroof belongs first, we say so. Homes that already have solar and need roof work go through our panel removal and reinstall service, and an existing system that stopped earning its keep — whoever put it up — goes to our solar repair service.
Historic designation worries people here more than it should. Pasadena designates both landmark districts and individual landmarks, and its design review turns heavily on what the street can see — exterior work that is not visible from the street is generally exempt from Certificate of Appropriateness review. That is exactly the lever a solar layout has. Keeping panels low and off the street-facing plane, where production allows, is both the better-looking answer and usually the one that keeps the array out of a design-review queue. On a landmark or Mills Act address we check the district's own conservation plan with city preservation staff early instead of assuming, because assuming is what turns a short permit into a hearing.
The foothill neighborhoods carry a harder recent history. The January 2025 Eaton Fire destroyed 185 structures inside Pasadena city limits, most of them in Upper Hastings Ranch and the hillside blocks beside it, and the city is still working through those rebuilds. Pasadena runs a Fire Rebuild Fee Waiver and Refund Program that waives city plan check and permit fees for eligible red-tagged single-family sites, and PWP is separately waiving its solar plan review and inspection fees during the rebate pilot — two different fee waivers landing on the same project. A rebuild is also the cheapest moment a house will ever have to take solar and storage, because the roof, the conduit runs and the main panel are all open at once. If you are rebuilding, bring us in while the plans are still moving.
Permits, interconnection, and commercial buildings on South Lake
Pasadena runs its approvals in a specific order, and getting it backwards costs weeks. PWP reviews and approves the system first, through its online application, before anyone applies for a building permit. The building permit then goes through the City of Pasadena's own Permit Center at 175 N. Garfield Ave — not LADBS and not LA County. After inspection, PWP sets the solar meter, moves the account onto net energy metering billing, and issues the Permission to Operate letter that lets the system legally switch on. We prepare and file all of it as part of every solar installation.
PWP's rules also shape the design itself. A system has to fall between 1 kW and 1,000 kW CEC-AC and may not be sized to produce more than 150% of the average annual consumption on your PWP billing record for the year before you apply. On a new build or an addition with no billing history to point at, PWP sizes it instead at 2 watts DC per square foot of conditioned floor area. Combined solar and storage inverter nameplate above 15 kW AC pushes the project onto PWP's Qualifying Facility interconnection and metering agreement and a heavier review; at or under that, it stays on the simpler track. The AC disconnect has to sit within eight feet of the PWP meter and in line of sight of it, which on an older Craftsman with a side-yard meter quietly decides where the rest of the equipment goes. If your service panel is too small to carry the array plus a battery, an electrical panel upgrade gets designed in from the start instead of surfacing as a change order.
Commercially, Pasadena's core is offices and retail rather than round-the-clock industry — the South Lake Avenue office corridor, the Playhouse District, Old Pasadena's retail blocks. Buildings like those tend to draw hardest during business hours, and the closer a building's peak sits to the middle of the day, the more of its own solar it consumes on site instead of exporting it at PWP's surplus rate. That is worth checking against your actual interval data rather than assuming, and it is the first thing we look at. Two things make 2026 unusually good for building owners here: the federal 48E investment tax credit is still available for commercial projects, and PWP's rebate pilot extends to commercial customers with tiered rebates up to $80,000 per meter. Start with our commercial solar page or the commercial solar Los Angeles overview.
We work the neighboring municipal-utility cities too — Glendale, on Glendale Water and Power, and Burbank, which moved new solar customers to net billing in 2026. Three cities, three different sets of rules, all within a few miles of each other. See the full service area list.
Pasadena solar questions
Who is the electric utility in Pasadena — is it SCE?
No. Pasadena is served by Pasadena Water and Power, a municipal utility owned by the City of Pasadena, which has run its own electric department since 1906. It is not Southern California Edison and not LADWP. PWP sets its own electric rates, runs its own solar program under Pasadena Municipal Code 13.04.177, and approves its own interconnections.
Does California's NEM 3.0 apply to solar in Pasadena?
No. NEM 3.0 is a California Public Utilities Commission decision, and the CPUC regulates investor-owned utilities such as SCE, PG&E and SDG&E. As a city-owned municipal utility, PWP is outside that jurisdiction. Pasadena solar exports are credited under PWP's own Net Surplus Compensation program. You can settle annually, where surplus earns PWP's average energy charge for the year plus 2.5 cents per kWh for renewable attributes, or monthly or bi-monthly, which adds a further 6.6 cents per kWh. We model both against twelve months of your bills.
Are there solar rebates in Pasadena in 2026?
Yes, locally. The federal residential solar tax credit ended December 31, 2025. PWP opened a solar and battery rebate pilot on April 7, 2026: $0.60 per watt for residential rooftop solar, $1.00 per watt for customers enrolled in PWP income-qualified bill assistance programs, up to $550 per kWh for battery storage, and tiered commercial rebates up to $80,000 per meter. The system must be installed on or after January 1, 2026 and must be customer-owned, so leased and PPA systems do not qualify. There is a lifetime limit of one rebate per residential service address, applications are due within 180 days of interconnection, and PWP states that program funds are limited and terms can change. We confirm what is still open with PWP before quoting it.
Do solar panels need historic review in a Pasadena landmark district?
Usually not. Pasadena's design review is driven by street visibility — exterior work that cannot be seen from the street is generally exempt from Certificate of Appropriateness review — which is why we lay arrays low and off street-facing roof planes wherever production allows. On a landmark or Mills Act address we check the district's conservation plan with city preservation staff before drawing anything. The building permit still goes through the City of Pasadena Permit Center at 175 N. Garfield Ave, and PWP must approve the system before that permit application is filed.
