I just reposted this from AR15.com, to save on time.
I got the portable solar charging panel done and tested it out today, 8/1/12 for 20 minutes, before a big rain cloud came in and forced me to pack up.
Pictures are worth a thousand words, so flame away!
Controller and 12vdc female socket mounted on plastic corrugated 'sign stock':
Controller from the side, 'triangle folds' keep panel in the vertical plane, but still allow for 'flat' packing':
Controller laying 'flattish':

Hinged panels in the vertical orientation, pink ropes are carry handles:
Panels from the side, they can be flipped for a more acute angle, when sun is directly overhead:
Shallow tilt, whole shebang charging the battery and powering an Xtar WP2 II Li-Ion charger, note case:
Open voltage before the big rain cloud blew in:

Facts and details:
Panels: Two Soplay 30w/1.74a (22"x16.5"x1") @ 5.5#. $178 shipped for both, with 2x12" Y connectors.
Battery: Power-Sonic 12v/12Ah AGM/SLA. $37 shipped.
Gun Case: Plano 4 pistol case cut to fit by me. $25 shipped.
Controller: Morningstar SS-10L 12v. This will take up to a 25v input, 10amp load. $70 shipped.
Mc4 Connectors: 3 pair of M/F for the Controller terminations. I ruined 3 halves, so get a few! $10 shipped.
Assorted adapters: Maha, LaCrosse 12v adapters, USB 2.1a adapter, 12v female socket. $35ish delivered.
Hardware: Hinges, bolts, nuts, washers, rope, Gorilla glue (wire was free!) aluminum bar stock: $20-$30.
Most of the stuff, I got new off of Ebay. The fitted case will hold two 12v/12Ah batteries, even though I only have one for now. The case will also hold the Maha C-9000, LaCrosse BC-700, Xtar WP2 II, all three 12v adapters and the little iPhone/iPad 2.1 amp USB adapter with 6' USB cord. The controller and its backing sits nicely on top of the fitted layer of foam.
Everything fits fits fine and closes. With 2 batteries, weight should be about ~22-23 pounds, maybe a tad less.
