Glenn County solar companies: rankings and reviews
Ranked by recent installs from CPUC records through May 2026, with review scores from every published customer review. Click any column to re-sort, or select companies to compare reviews side by side.What this data covers: These counts come from PG&E interconnection records, the investor-owned utility service in Glenn County. Homes served by municipal or cooperative utilities interconnect through their local utility instead and do not appear in these records, so installers focused on those areas show fewer installs here than they actually build.
Every company with 50 or more verified Glenn County installs, ranked by recent 2025-26 activity. All columns are Glenn County-specific. The county's 42 active installers in 2025 include smaller and occasional operations below that bar. Acquired brands count under their current parent: SolarCity under Tesla Energy, Vivint Solar under Sunrun. No per-installer price is published in the table.
Verified installs
Residential systems in Glenn County public records listing that company as installer of record, all time. Real local activity, not review stars.
% leased
The share of that company's Glenn County systems recorded as third party owned, a lease or power purchase agreement. Ownership mix, not quality.

Solar.com Scores are live for 9 of the 13 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.

Who is the best solar company in Glenn County?
The best company depends on your roof, utility, equipment needs, and whether you want to own the system or use a lease-style agreement. The table ranks installers by verified Glenn County interconnection activity, not by ratings or paid placement.
How are Glenn County installers ranked here?
The list includes every company with at least 250 verified Glenn County installs in CPUC Rule 21 public records through May 2026, ranked by recent 2025-26 activity with all-time installs as the tiebreak. Every column is Glenn County-specific. Acquired brands are combined with their current parent, so SolarCity records count under Tesla Energy and Vivint Solar records count under Sunrun.
What does % leased (TPO) mean?
% leased (TPO) is the share of that installer's recorded systems that appear as third-party owned. It helps you see whether an installer historically skews toward owned systems, leases, or a mix.

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.
