Installer profile
POCO Solar Energy Inc
POCO is one of the few Bay Area solar companies whose age claim can be traced through state records rather than taken on faith. The current license, 879366 with B General Building and C46 Solar, was issued June 13, 2006 and runs current and active through June 2028 with no complaint disclosure. Cofounder Gregory Allen Cordero's CSLB personnel record ties him to two expired predecessor Santa Clara licenses, POCO Services from July 1984 and POCO Solar Energy from 1995, corroborating continuous licensing under the POCO name back to the year the founders say they started. BBB rates the company A+ and dates the business start to January 1, 1984.
Know what kind of solar company this is. The headquarters is Santa Clara, at 3345 Keller St, despite the Mountain View listing; Mountain View is one of many Santa Clara County cities in its service area, which covers five counties from San Mateo down to Monterey. And the business is weighted toward solar pool heating alongside PV. The heritage story centers on solar-heated swimming pools, the workers comp policy carries a plumbing classification consistent with pool work, and its flagship offering includes the CoolPV hybrid that generates electricity and heats the pool at once. The company claims over 12,000 systems installed and over 4,000,000 square feet of collectors, but those are self-reported figures with no third-party verification, and POCO appears in neither 2026 Solar Power World list.
Two blind spots to press on before signing. No workmanship warranty is published anywhere fetched; the FAQ points only to the typical 25-year manufacturer panel warranty, which covers the hardware, not the installation. And the clean-looking BBB page carries less information than it appears to, because BBB publishes no complaint counts or details for this company at all, so the record is silent rather than spotless. For a pool heating job or a combined pool-and-PV project, this is an obvious quote to get. For straight PV, get the workmanship warranty in writing and ask who actually installs.
The evidence
CSLB records corroborate the 1984 story: qualifying individual Gregory Allen Cordero associated with predecessor license 459894 (POCO Services, Santa Clara) on July 23, 1984 and with 703071 (POCO Solar Energy) in 1995, both now expired, before the current license 879366 issued June 13, 2006. BBB dates the business start to January 1, 1984, with the current corporation formed February 4, 2005.
The CSLB license shows no complaint disclosure, and searches found no attorney general, district attorney, PUC, FTC, or DOJ action naming the company. BBB rates it A+ and states no government actions, but publishes no complaint counts and no complaint details, so the BBB record is an information gap, not evidence of zero complaints.

The company claims over 12,000 solar energy systems installed, over 4,000,000 square feet of solar collectors, and over 10,000 customers, with the mix heavily weighted toward pool heating. All figures are self-reported; no POCO entry appears in the 2026 Solar Power World Top Solar Contractors table of 388 entries or the 2026 Top California Solar Contractors table of 91 entries.

No workmanship warranty is published on the fetched pages. The FAQ states only that solar electric panels typically come with a 25-year manufacturer warranty and that systems can produce for 30 years or more with proper care, which describes the hardware, not POCO's obligation for its own installation work.

How to read this
This B credits what the state can confirm: four decades of continuous Santa Clara licensing under the POCO name with nothing disclosed against it. It does not credit the 12,000-system claim, which no third party has verified, and it cannot credit a warranty that is not published. If your project is pool heating, this record is about as strong as the category offers. For PV, ask for the workmanship warranty in writing and for recent PV-specific references, because the public evidence leans toward the pool side of the business. 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.
