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 ...

Of course the lower slide-out panels would go in and out under power using a remote so you don't have to go on the roof.
A CD player tray on steroids perhaps
EDIT 140w and 8.4 Isc. 130w should be 8.2, so 140/130 x 8.2 = 8.83
With the two 150s you get 2 x 8.95= 17.9 for $330
With the two 140s you get 2 x 8.4 = 16.8 for $308
If you got one less amp all day for 8 hours that would be 8 AH. How big a deal is that in your scenario? Only you know that sort of thing.
With flat you will not get rated Isc unless sun is really high anyway. I don't know if you can compare relative off-angle amps to relative Isc amps in proportion with different panels that may have different cell designs for light spectrums or whatever- all too complicated.
