What the Dataset Shows

  • California has more observed records in the source dataset (1,921,220 vs 161,816)
  • California has lower average cost ($4.46/W vs $4.47/W)
  • California has more total capacity (17,997 MW vs 7,765 MW)

Record counts and reported capacity reflect coverage in the LBNL release, not an overall ranking of state solar quality. A homeowner decision also depends on roof orientation, current utility tariffs, financing and local programs.

Primary dataset: LBNL Tracking the Sun 2024 release. Values are aggregates of observed records, not complete statewide totals.
