Orange 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 SCE and SDG&E interconnection records, which cover most of Orange County. Anaheim homes are served by Anaheim Public Utilities, a municipal utility that does not publish comparable records, so installers focused on Anaheim show fewer installs here than they actually build.

Every company with 250 or more verified Orange County installs, ranked by recent 2025-26 activity. All columns are Orange County-specific. The county's 621 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.

Recent installs

Orange County installs recorded in 2025 and 2026. A big historical name with thin recent activity is a different signal than a company building every week.

Verified installs

Residential systems in Orange 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 Orange County systems recorded as third party owned, a lease or power purchase agreement. Ownership mix, not quality.

Solar.com Scores are live for 42 of the 83 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.

FAQ

Who has the best solar company reviews in Orange County?

The Solar.com Score column ranks review quality directly: we read the full text of every published customer review of the county's established installers and score what reviewers actually report, 0-10, across sales integrity, price transparency, communication, timeline reliability, workmanship, and after-install support. Sort the table by Solar.com Score or select companies to compare their reviews side by side.

Who is the best solar company in Orange 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 Orange County interconnection activity, not by ratings or paid placement.

How are Orange County installers ranked here?

The list includes every company with at least 250 verified Orange 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 Orange 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.

How does solar.com pricing compare in Orange County?

Orange County has a median reported install cost of $4.13/W for owned CPUC records. Solar.com base pricing starts from $2.54/W, before site adders, with direct bids backed by the Best Price Guarantee.

Does being listed mean solar.com recommends that installer?

No. The public table reports verified installation volume only. The companies that bid on your home are separately vetted before they can compete through solar.com, and nobody can buy public placement here.

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.
