What to ask before you hire

About Trinity Solar LLC

  • Ask for their license number and check it with the state.
  • Ask what the warranty covers and for how long, in writing.
  • Search their name on the Better Business Bureau site, and read their reviews.

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?
  • Is my roof good for 25 more years, and what if it needs work first?
  • Who handles the permit and the utility's approval to turn it on?
