Cosmic Solar and Roofing
Cosmic Solar and Roofing earns a spot on a North County shortlist, with one name caveat and one paperwork demand. The name caveat: no entity called Cosmic Solar and Roofing exists at CSLB. The licensee is Cosmic Solar Inc, license 831831, at the same Vista address and phone, with the license originally issued in February 2004 and reissued to another entity in March 2009. BBB displays that same license number for the brand, so the link is direct, but the exact name on your contract should be Cosmic Solar Inc. The license is current and active with C-46 Solar, C-10 Electrical, B General Building, and C-39 Roofing, and its workers comp policy carries a roofing high wage labor code, which is what you would expect from a company doing its own roof work rather than brokering it.
The complaint record is the lightest in this track: 2 BBB complaints in three years, none closed in the last 12 months, against an A+ rating. Both deserve a read. A March 2023 complaint reported roof leaks the company verified came from a defect in its own solar installation, and a December 2023 complaint said a 2015-installed inverter that broke in August stayed unfixed into December despite warranty coverage, and alleged the website claimed BBB accreditation when BBB lists the company as not accredited. Both BBB pages read on August 27, 2026 still show not accredited. That is a consumer allegation, not an enforcement finding, but it is an honesty flag worth asking about directly.
The real gap is the warranty. The site offers an unconditional guarantee for complete customer satisfaction with no duration, no scope, and no document. For a company whose own complaint file includes a verified installation-caused roof leak, that is not good enough. Volume, at least, has a third-party anchor: rank 64 on the 2025 Top California Solar Contractors list at 1,987.65 kW, and a Solar Power World supplier page reporting 33,795 kW installed since founding. Get the workmanship and roof-penetration terms in writing with a number of years on them, and this is a solid two-decade local operator.
The evidence
License 831831 was originally issued February 4, 2004, matching BBB's business start date, and was reissued to another entity March 13, 2009, matching BBB's incorporation date; BBB counts 21 years in business, while the Solar Power World supplier page states a 2007 founding, so the operating history is two decades even though the exact corporate lineage shifted in 2009.

No complaint disclosure link displayed on license 831831, meaning nothing publicly disclosable rather than no complaint ever; BBB shows an A+ rating with only 2 complaints in three years, one reporting roof leaks the company verified came from a defect in its solar installation and one alleging a slow warranty repair plus a website claim of BBB accreditation that BBB's own not-accredited listing contradicts, and the searches run found no government enforcement action against Cosmic Solar Inc.
Solar Power World ranks Cosmic Solar 64th on the 2025 Top California Solar Contractors list at 1,987.65 kW as a primary-service installer, and its supplier page reports 33,795 kW installed since founding; the company is absent from the populated 2026 national contractor and installer tables.

CSLB lists Cosmic Solar Inc as a current and active Vista corporation on license 831831 with C-46, C-10, B, and C-39 classifications expiring March 31, 2027, with a $25,000 contractor bond effective February 13, 2026, qualifier Bahram Shadzi holding 10 percent or more ownership, and State Fund workers comp to March 1, 2027; the consumer brand name Cosmic Solar and Roofing does not appear on the CSLB record, so confirm the contract names Cosmic Solar Inc.

The site states an unconditional guarantee for complete customer satisfaction with no duration or scope, a company blog post notes that most systems come with installer workmanship warranties without stating Cosmic's own term, and no published workmanship warranty duration was found anywhere read, so every warranty term must come from the signed contract.

How to read this
This B rewards a long, quiet license record and docks the things the company will not put in writing. Nothing here suggests you should avoid a quote; it suggests you should negotiate one properly. Ask for the workmanship and roof leak warranty as a document with a stated number of years, confirm the contract names Cosmic Solar Inc and license 831831, and ask directly why the website and BBB disagree about accreditation. Straight answers to those three raise your confidence past what any letter grade can. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
