A flat board, panel, what not traveling straight forward will not create lift. It requires a air foil that will increase the wind speed over the top of the wing via up slope affect and then a decline in the foil to create low pressure. Tilting the wing will increase the lif but too much tilt and you lose the affect nd stall.
Now if you were nose high with the panel it would produce some lift but the main force would be from below at that time, kind of like flying a kite.
One thing I have noticed over the years is the older panels have a heavier duty frame on them than the newer panels, even those from the good ol USA. Obviously not all of the cost savings have come from just the Chinese dumping on the market.

I'll be looking for help with installation here soon. I want to do it to my level of quality but it's not been a good winter physically for me so I'll look for installers. On the other hand we may be able to help each other out if you think you are up to it. I have all of the tools, saws, cutters, crimpers, drills and ladders needed for install and few neighbors that may even help with the heavier lifting. I plan on bribing them handsomely when it comes time to move the 8-D's.
So if you are interested, let me know. I'll need to pick up the mounting hardware just to get the panels up, after that I can wire at my own pace. That way we could get your wires ran and crimped too.
