Roll Up Solar Panels / Ogre MPPT Controller
I would LOVE to get 10-12 amperes of 12 volt grade charging for my new group 31 Lifeline. But I have a motor-scooter size toad, that forces me to the roll-up kind of solar panel, and woe is me, the...

Mex,
I've seen reports by those who used these unisolar 68 watt and 132 watt 'roll up panels, as portable panels that were rolled and unrolled often, that they began to break down rather quickly when rolled and unrolled often.
Also the sides of the panels are still sticky Butyl and stick to and make a mess on anything they touch
Unisolar said they should not be rolled under such and such a diameter, and I found mine shipped to me about 4 inches under that diameter. I think it was 22 inches but dont quote me.
I really think trying to implement these as a portable solution is not wise. People seem to think they are indestructible, but there are lumps where the diodes reside and I imagine enough pressure on one of those could break it.
I think I'd be getting 2 framed panels and attaching locking handles to one side and a piano hinge on another if I were to go portable.
I have the 68 watt unisolar pvl68 with the mc3 connectors, and it does seem to do well in lower light, but it sure takes up a lot of space to make those 68 watts, and was not a simple peel and stick in my application. Going over the crown in my roof caused a couple kinks here and there and these kinks are now getting ugly and I fear for its ultimate lifespan.
It will be 3 years installed, in february '15.
