I made my own version, although it is 43x28, 200W. Just get any of the 'bendable' panels available on Amazon, built frames for each from aluminum stock from HD or Lowes. I used the V shaped pieces and self tapping screws, join them with a piano hinge and tack on suitcase handles and some latches to keep the whole thing closed. The panels come with nice thick foam for padding. I sandwich the suitcase in these and wrap a couple of bungies around the whole thing for safety. I added 20' of wire so I can move the panels around to 'chase the sun'. This suitcase weighs about 15 lbs. produces 8AH in good sun. About $400 including a PWM controller.
