Portable Solar Plan
I have decided to go portable for my solar for several reasons 1) I like the option to move them around, 2) want to use them before committing to additional on my camper or trailer, and 3) I think it'...

I come down on the other side of the PWM/MPPT debate. As kohldad said the higher thee panel voltage the more benefit you get from an MPPT controller. For limited area roofs like our campers, an MPPT controller can make 2 panels perform as if you had (almost) 3. I have the Renogy 100W panels (Vmp = 18.9V). Two panels with a PWM controller would give me 10.58 amps to the batteries. With an MPPT controller I'll get 14 amps, at 14.2v. With 3 panels, PWM = 15.87 amps, MPPT = 21.12 amps. With 4 panels, PWM = 21.16 amps, MPPT = 28.16 amps. (I have 4 panels)
The MPPT is more expensive, but to get the most current from the area I have I feel it's worth it.
YMMV
