Installer profile
Option One Solar
Option One Solar is a reasonable company to invite into a competitive bid process. CSLB lists Option One Corporation, doing business as Option One Solar, with active C-10 Electrical and C-46 Solar classifications issued in 2013. The record showed no complaint-disclosure section, citation, accusation, or civil-judgment section on the research date. The company says it handles design, engineering, procurement, permitting, construction, and interconnection in-house, and says licensed crews take care of construction through utility interconnection. That is a stronger operating claim than a generic sales-only pitch.
It still needs specifics. The homepage advertises a 25-year warranty, but does not identify its workmanship coverage, exclusions, carrier, or whether it is standard in every contract. The same page claims Trusted Since 1970, 54+ Years in Business, and Est. 2013, while the CSLB license was issued in 2013. Those statements do not produce a clean origin story. BBB's profile is A+ but its complaints page displays no count or published complaint theme; a recent review includes consumer allegations that are not independent BBB findings. This is a B because the active licensing record is solid and the gaps are clarifiable, not because the marketing language deserves a free pass. Make the labor warranty and contracting responsibility specific before choosing the bid.
The evidence
CSLB issued license 985340 on July 22, 2013, providing a multi-year licensed record, while the homepage simultaneously claims Trusted Since 1970, 54+ Years in Business, and a 2013 establishment and BBB lists 54 years in business, conflicting statements that leave the company's origin year unconfirmed rather than verified.

The CSLB detail page displayed no complaint-disclosure section, citation, accusation, or civil-judgment section, meaning nothing publicly disclosable was displayed as of August 24, 2026 rather than a certified absence of all complaints, while BBB shows an A+ rating without a displayed complaint count or theme and recent BBB review text includes consumer allegations about bait and switch, contract changes, and battery-status or contract issues that are not independent BBB findings, with no separate government enforcement action confirmed.

Option One Solar was absent from the 2026 national, 2025 California, and 2026 installer Solar Power World lists, and the company's Southern California service description and stated in-house project model do not provide an independently reported installation total, employee count, or megawatt figure.
CSLB lists Option One Corporation, doing business as Option One Solar, at 13581 John Glenn Road, Suite A, Apple Valley, with active C-10 Electrical and C-46 Solar license 985340 through July 31, 2027 plus a contractor bond and workers compensation, while the company's stated in-house model is a company claim rather than a CSLB finding but gives a buyer a concrete scope question to put in the contract.

Option One Solar advertises a 25-year warranty and dedicated support, but the reviewed page does not identify it as workmanship coverage or publish coverage, exclusions, or carrier details, so treat it as a company claim until the agreement specifies the labor work covered, duration, and correction responsibility.

How to read this
A B grade says the evidence is broadly favorable, but it does not turn an undefined warranty into a guarantee. Use this profile to push the quote past headline claims. The contract should spell out the installation labor warranty, each project handoff, the legal entity that performs the work, equipment responsibility, and the escalation path after PTO. The useful grade is the one that makes the buyer ask better questions. 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.
