Adding rooftop solar in 2026 LA has gotten more complicated than it was a few years ago. The CPUC's Net Billing Tariff (NEM 3.0) reset export economics for SCE and other IOU customers, LADWP operates its own evolving net-metering program, interconnection queues have stretched across both, and battery storage has become essentially mandatory for solar to pencil at IOU rates. Here's what's actually happening and how to navigate it.
NEM 3.0 Reality Check
Under NEM 2.0, you got retail-rate credit for solar sent back to the grid. Under the CPUC's NEM 3.0 / Net Billing Tariff (active since April 2023 for the IOUs - SCE, PG&E, SDG&E), export credits are 70–80% lower. LADWP customers remain on LADWP's own net-metering rules, which the utility has been reviewing for its own successor program. Either way, solar-only systems now pay back in 12–15 years instead of 6–8 for IOU customers, and the most reliable way to restore the original economics is paired battery storage.
Why Battery Storage Changes Everything
Storing your daytime solar production and using it during 4–9 PM peak hours captures the full retail value of every kWh. A 10 kWh battery (Tesla Powerwall 3, Enphase IQ Battery 5P, Franklin aPower) cuts payback from 12–15 years back to 7–9 years and gives you whole-home backup during outages.
Federal Tax Credit Still 30%
The IRA's Residential Clean Energy Credit (25D) is still in effect at 30% through 2032 - covering solar, battery, and associated electrical work. A typical $35,000 LA solar+battery install nets a $10,500 federal credit. SGIP rebates for battery storage still exist for qualifying low-income, fire-zone, and medical-baseline customers.
Interconnection Queue Tips
LADWP interconnection currently runs 8–16 weeks from PTO submission. Submit complete paperwork the day after installation - incomplete submittals get bounced and start the clock over. We handle all of this in-house and follow up weekly so projects don't get lost in the queue.
Don't Wait for the Math to Get Worse
Electricity rates in LA have risen 28% since 2022 and forecasts call for 5–7% annual increases through 2030. The longer you wait, the better your solar+battery math gets - but you also pay higher utility bills in the meantime. Most homeowners hit positive cash flow in month 1 with proper financing.
