Solar.com Scores are live for 19 of the 47 ranked companies. Companies marked “Not yet scored” have fewer than 20published reviews or are still being analyzed; scores appear as each company's full review record is processed. Select up to 4 companies to compare them category by category.

% leased counts systems recorded as third party owned, meaning a lease or power purchase agreement. The remainder are customer owned. Active installer counts include every company that filed an interconnection that year, down to small and occasional operations. Counts come from PG&E, SCE, and SDG&E interconnection records; homes served by municipal utilities like LADWP, SMUD, and city power departments interconnect through their local utility instead, so companies focused on those territories show fewer records here. The Solar.com Score is computed from the full text of each company's published customer reviews (star ratings and review counts sourced from Google and Yelp); it is separate from the install ranking and never for sale.

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.
