Installer profile
AltSys Solar Inc.
Yes, AltSys Solar Inc. is worth putting on a quote list. The state record is unusually straightforward: license 944549 is active, carries both C-46 solar and C-10 electrical classifications, and was issued in 2010. CSLB displayed a contractor bond and workers compensation on the record, with no citation, accusation, civil judgment, or complaint disclosure link shown when it was checked. That is not a promise that nobody has ever had a dispute. It is still meaningful public-record evidence.
The warranty claim is better than the vague language many installers use. AltSys says every PV system it installs includes a 10-year warranty. The missing piece is the contract detail: the published page does not spell out exclusions, transferability, or who is legally responsible for the promise. The company was also absent from the three Solar Power World lists reviewed, so there is no independent project count to turn into a volume claim. Get a quote, then make the written labor warranty and service process part of the comparison.
The evidence
CSLB issued AltSys Solar Inc. license 944549 on March 17, 2010. BBB reports incorporation in 2008 and a business start date in 2009, while the company does not state a founding year. The state record establishes a long licensed operating history.

No CSLB complaint disclosure link, citation, accusation, or civil judgment appeared on the reviewed license detail, and BBB's complaints page displayed no three-year count or published complaint detail. That is limited favorable public-record evidence, not proof that no customer has ever filed a complaint.

AltSys was absent from the reviewed 2026 national, 2025 California, and 2026 installer Solar Power World lists. The company describes itself as a Central Valley installer, but no independently reported installation total or megawatt figure was found.
CSLB lists AltSys Solar Inc. as an active corporation with C-46 Solar and C-10 Electrical classifications. License 944549 was issued March 17, 2010 and expires March 31, 2028; the detail page lists a $25,000 contractor bond and workers compensation coverage.

AltSys says every PV system it installs includes a 10-year warranty. The published statement does not identify exclusions, transferability, the legal obligor, or the remedy if labor work fails, so treat the term as a company claim until it appears in the contract.

How to read this
A B does not mean the bid is automatically the right one. It means the license record and operating history clear the first screen better than most thin-data profiles. Ask AltSys to attach the 10-year labor warranty, including exclusions and response time, to its proposal. Then compare equipment, production assumptions, roof scope, and cash price against another properly licensed installer. 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.
