Solar panels in Long Beach

The city says it plainly in its own solar permitting bulletin: Southern California Edison is the utility providing electrical power for the City of Long Beach. Because SCE is investor-owned, it follows the CPUC's Net Billing Tariff — the rules most people call NEM 3.0 — rather than a city-run solar program like the ones in Burbank or Glendale.

Under net billing, the power you export is credited using the state's Avoided Cost Calculator, which sets a separate value for each combination of month, hour, and weekday or weekend — not the retail rate you pay when you buy power back. A kilowatt-hour sent to the grid on a mild spring morning and one sent on a hot September evening are worth very different amounts.

The practical consequence is simple: a kilowatt-hour you keep is worth more than one you sell. So the design question in Long Beach is not how many panels the roof will hold, it is how much of the array's output lands inside the hours you are actually drawing power. That sum works out differently here than it does inland, because the coastal morning cloud shaves the front of the production curve — a Long Beach roof tends to deliver a later, flatter day, which changes how much of it you can absorb yourself before the evening peak arrives. Storage is worth pricing on some of these homes and not on others. We run it both ways and hand you both sets of numbers.

One thing Long Beach does not have is a second layer of rules on top of Edison's. The city has studied community choice aggregation more than once without joining a program, so unlike Downey and Whittier next door — both Clean Power Alliance cities, where the generation and delivery halves of an export credit come from two different organizations — a Long Beach solar account settles under a single set of program terms rather than two.

Two calendar dates do most of the work here. The Net Billing Tariff applies to interconnection applications submitted on or after April 15, 2023, so a system already interconnected before then sits under the older rules and should not be changed casually. And the federal residential purchase tax credit ended December 31, 2025 — zero-down lease and PPA structures still pass incentives through, and our lease-vs-buy guide walks through the trade-offs.

Belmont Shore, Naples, the Peninsula, and the streets around Alamitos Bay sit close enough to the water that hardware selection matters more than panel branding. Salt mist works on module frames, fasteners, and junction boxes, and any place two different metals meet at a mounting point is a candidate for galvanic corrosion. There is a published test for this — IEC 61701 salt-mist corrosion testing — and coastal blocks get modules and racking rated for that exposure, with corrosion-resistant fasteners, instead of the inland default spec.

The weather is a design input here, not small talk. The marine layer locals call May Gray and June Gloom lays low cloud over these blocks on late-spring mornings and usually burns off around midday, and the water keeps summer afternoons off the highs an inland Valley address reaches. Production leans late in the day and the bill you are offsetting has a different shape than a Woodland Hills bill. That changes the sizing, not the verdict.

Commercially, the port shapes the building stock. Warehouse, logistics and industrial space runs up the I-710 corridor from the harbor, and the offices at Douglas Park sit on the old aircraft plant grounds beside Long Beach Airport. What those buildings share is a load that happens in daylight, and net billing treats a building that burns its own production far better than one that exports it. That is why the commercial case here can still hold up on a roof where the house across the fence is marginal.

Two Long Beach details are worth knowing before a commercial budget. The 38.4 kW express permit path is open to nonresidential and multi-family roofs, not just houses — but fire review is required on both, so the express label does not mean no review. And on the federal side, the residential purchase credit is gone while the commercial 48E investment credit is not; what changed in 2026 is the timing, so when construction starts and when the system is placed in service now decide whether a project qualifies.
