The Contractors State License Board lists complaints it has sent for legal action, citations it has issued, and warning letters. A complaint or accusation is an allegation, not a finding. A citation is the board's finding that a rule was broken; the contractor can appeal it. Complaints closed in the contractor's favor are never listed. Most contractors have no items.

Worth asking any solar installer
- Can you show me proof of liability insurance and your bond?
- What size system, which panels and inverter, and what will it make in a year?
