Sounds great, I look forward to hearing about your experiences with it!!!
Here are some pics:
I don't have any photos after painted and the vinyl cover on the front.
My biggest issue now is trying to get the BBB's to be reliable. They are very flaky.
The vinyl works well. I don't notice any glare, however, I didn't do a great job on installation. There are some wrinkles, which are somewhat noticeable during the day. At night, you can't tell any difference. That issue is my laziness. When the vinyl shipped, I should have removed from the box and laid out in the sun for a few hours. Because I didn't, it was hard to get the creases out from where it was folded during shipping. The vinyl is great at water proofing. My matrix is covered (by my front porch), so I didn't do much in water proofing the box, but I'm confident it would be water proof if I would have caulked the joints. If my matrix wouldn't have been covered, I would have tested with a water hose before installing the panels, just to ensure water tight joints.
You asked:
"Is it ~ 7.3ft wide x 3.15ft tall?"
It is actually 11 panels (69.2") by 7 panels (88.1"). My next post will show a layout.
I used Boscoyo parts for joining each panel. I then used aluminum angle to stiffen each "row". Then attached the angle to the enclosure via 90° brackets, you can see in one of the photos. This worked well.
I started off using 80/20, but that didn't work out well, so good ole' lumber was used. It is sturdy enough for what I needed.
I hope this was helpful info and I didn't ramble too much. I'm in multitask mode and that sometimes means confusion.
