What the Dataset Shows

  • Arizona has more observed records in the source dataset (293,541 vs 204,286)
  • Texas has lower average cost ($3.92/W vs $4.47/W)
  • Arizona has more total capacity (7,216 MW vs 2,252 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.
