I took some time this weekend to finish up the panel. I ended up going with hot glue to adhere the cells, wire, and diode to the board. I'm not sure this was a great idea due to the low melting temperature of it, but we'll see. Again, on an overcast (but light at least) day, it was producing upwards of 17V. I then hooked it up to a computer fan and the voltage dropped to 7V and .14A. So, still not putting out the power it should, but it was overcast too, so I'll need to do further testing to make sure its going to work out good.
Cells all glued in place. No more rattling around. I check the tabbing and cut any excess off that I thought might short cells.
I also shortened up the leads and put connectors on the ends. This will allow easy removal from the car if/when I need to.
