Treepublic

Yes, get a quote. Treepublic is one of the few Los Angeles metro installers whose volume you can actually check. The 2026 Solar Power World lists rank it 143rd among all contractors nationally and 19th among installers, with 13,643.37 kW installed in 2025, and the 2025 California list puts it 32nd in the state at 11,711.32 kW. That is third-party published data, not a brochure claim, and most companies this size have nothing comparable on record.

The paperwork checks out with one naming wrinkle. The licensed entity is Treepublic Inc, doing business as Treepublic Solar, on license 996593, active with C-46 Solar and C-10 Electrical classifications, issued September 10, 2014 and expiring April 30, 2028. The website brands itself Treepublic and, on project pages, Treepublic Energy, which is a previous name on the same license, so all three names trace to one record. Note that CSLB reissued the license to another entity on April 26, 2022, the same date qualifying individual Omar Nasser certified 10 percent or more ownership. The complaint side is quiet: no publicly disclosable CSLB action appeared on the record when read, and BBB shows exactly 1 complaint in the last three years. The A- rating instead of A+ exists only because the company never responded to that one complaint, which is careless but not a pattern.

The gap that keeps this at B: no workmanship warranty terms are published on any company page we fetched. A third-party review site says the company site mentions a 25-year warranty, without specifying coverage, and that is not evidence of terms. The company also does not state a founding year on its own site; the about page says it has been investing in next economy ideas since 2008, while BBB dates the business start to September 10, 2014, matching the license. One more thing worth knowing: Treepublic also operates as an equipment distributor to over 20 countries, a dual installer-distributor model you rarely see at this scale. Before signing, get the warranty duration, scope, and exclusions in writing, because right now they exist nowhere in public.
