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.
