Hi Glenn,
No, I haven't seen the Astropower laminates. I did install the BP laminates I bought in Nov 2003 and can say that you will need to have a support structure for the panel.
I used the same clips I used on my framed photo-watts with out any frame, and it is not stiff enough. I intend to go back a put aluminum 2"x2" used for screen enclosure structures as a rail to stiffen it up
With Sun Electric you better pre-pay, or get in writing they will hold the panels , but what ever they have will produce power they sell them as.
Texas to Miami is a long trip and a lot of fue
l … it would be much cheaper to ship the panels, something to consider
