What to ask before you hire

About Quantum Solar Designs Inc

Do not hire until the contractor shows you an active license.
Ask what the warranty covers and for how long, in writing.

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?
