Ok, you guys have me convinced. It's VHB for me.
I looked at the AM Solar brackets. Very nice, but they cost $80 per panel... So I got a renology tilt bracket to try out. My plan is to adapt the renology mounts: using two of the extrusions for the back of a panel and then cutting short sections of 2"x2" aluminum angle for the attachment feet.
I realize that I will seldom, if ever tilt the panels, but this should be cheap/easy mounting and allow the option of tilting.
Cheers,
Walter
