I purchased 10 pounds of these cells and am currently building my own panels. I learned one thing right off: DO NOT use fiberglass resin to mount the cells! The different expansion rates destroy the cells every time it heats up.
I should take some pics of the assembly process, since it can be tricky and it might help someone else.
Breakage was around 30-40 percent, but with some super glue and a soldering iron, many of them were salvaged. The only thing I haven't come up with yet is a clear covering to protect the panels.
