Solar Installation Cost in Los Angeles, CA (2026)
A solar installation in Los Angeles costs $2.75–$3.75 per watt installed (pre-incentive), with a typical mid-size solar system running $18k–$29k. Small projects start around $13k; large or high-end work can reach $45k or more.
Costs in Los Angeles sit near the LA County baseline, shaped by LADBS permit complexity, dense urban logistics, and elevated trade-labor rates.

What Affects Solar Installation Cost in Los Angeles?
- System size (kW): drives 60–70% of cost; size to your last 12 months of bills, not your roof area.
- Panel brand: Tier-1 panels (REC, Q-Cells, Panasonic) add $0.20–$0.40/W over generic Tier-2.
- Roof condition: a roof with <10 years remaining should be replaced first; removing/reinstalling later costs $3k–$8k.
- Battery storage: Tesla Powerwall 3 adds $13k–$18k installed; under NEM 3.0 the payback math usually favors batteries.
- NEM 3.0 export rate: post-2023 LA solar exports earn ~75% less than NEM 2.0, which changes sizing strategy.
- LADWP / SCE interconnection: PTO (permission to operate) adds 2–8 weeks after install.

Solar Panels Only vs Solar + Battery Storage
Solar-only systems run $15k–$45k pre-ITC but lose 70–80% of export value under NEM 3.0; adding a battery ($13k–$18k) recovers most of that and provides outage backup.
Solar for EV Charging vs Solar Panels Only
EV-sized systems (10–14 kW) cost $27k–$51k but offset both home and vehicle electricity; right-sizing to your annual kWh including EV miles maximizes the 30% ITC.
How to Get the Best Price on a Solar Installation in Los Angeles
- Get 3 bids through Keystone Connect with the same panel + inverter SKU on each — prices vary $0.40–$0.80/W between installers.
- Claim the 30% federal ITC the year you install; LA-specific rebates (DAC-SASH) may also apply if income-qualified.
- Size to your last 12 months of bills, not future projections — oversizing wastes capital under NEM 3.0.
- If your roof is 10+ years old, bundle re-roof + solar to avoid a $3k–$8k removal-and-reinstall later.
