Does it comprise of two rows of cells? If it does, from my experience it will be difficult to 'stand it up' and face it towards the sun. It may be possible to place it on the vehicle windscreen. I had a Giant setup and it was very difficult to manage. It was a shame because the panel itself was excellent.
Projecta (and possibly some others) units are a 'single row with detachable legs that enable it to be pointed towards the sun.
