Panels For Mena
Mena will be using PWM so Isc and panel cost is what counts. He was looking at two 150w panels with Isc of 8.95 and $165 each. So that is lower Isc than usual for 150w (9.46a usual) but cost per ...

The somewhat higher voltage panels the OP chose are not that bad for his application. He'll be in an hot environment where voltage headroom is easily lost.

I guess if adding panels is an option, then making it easy to add panels is paramount. A Junction box wired to the charge controller with oversize wire, will make add-ons simpler, and more likely to occur.
BFL, I WAS thinking of stealing PT's idea of stacking panels. The upper panel would be fixed and the lower panel would slide out. I could put the lower panel on bottom mount drawer slides (I'm using bottom mount, heavy duty drawer slides on my battery tray). I'd probably need a 4" L bracket for the top panel.
