No, this was part of a group buy program in my area, which was designed to reduce prices. I ended up turning them down because it was still more expensive than it seemed like it should be, and they were going with an older single inverter system instead of a newer and more efficient micro inverter system.
I’ve heard the door to door guys tend to massively upcharge. I haven’t had any come through here, though, so I don’t have any direct experience.
