Cost and timing
Solar in Los Angeles: $18,000 to $40,000
Half of 3,193 installs from January 2021 to December 2023 cost an amount in this range.
How to read this range
These are prices homeowners paid, as installers reported them to state programs. Lawrence Berkeley National Laboratory collects them in its Tracking the Sun data. A quarter paid less than this range, and a quarter paid more. The prices are before the federal tax credit.
Permit timeline
Across Los Angeles, a solar system permit stays open about about 8 months, from permit to final inspection
This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. Waiting for the permit adds about 62 days. How long solar system jobs take.
