About this data
- Counts are City of LA electrical permits for 1-or-2-family homes, by issue year: a permit means the work was approved, not that it finished. Revisions to an earlier permit aren't counted again.
- Solar sizes come from the permit's work description; batteries are found by keywords (battery, energy storage, Powerwall) because the data has no battery flag.
- LADBS doesn't record installer names or prices, so those figures aren't available for the City of LA.
