Roll up solar panels for portability?
At a faire I frequent, one person had three 20 foot long roll-up solar panels, similar to this. I wonder if anyone has any recommendations for panels that are more durable, and designed for more se...

OP asked about portable.
It rolls up compact, but I'm not sure how well it will take repeated rolling-unrolling. Without some sort of rigid backing you would have to lay it down on the ground, this doesn't sound good.
I read that amorphous panels work more efficiently than crystalline panels in low-light conditions - more amps per nominal wattage. But in full sun 130W is still 130W.
With 24V panel you will need MPPT, and the cheapest half-decent one is ~$150.
