It is also cheaper to get it installed if you're already doing a roof replacement. Especially if you're getting built-in modules instead of retrofit, since they replace some of the roof surface instead of going over it.
Indeed, the best time to install is during a roof replacement. If one can afford it, standing seam metal roof, racking mounted with friction mounts (deck penetrations are the enemy and to be avoided whenever possible, to prevent future water intrusion), and the entire system (roof deck and panels) should last 40+ years. Last roof and solar you put on for your life for many of us.
