[QUOTE="wooly, post: 119227, member: 548"] Perhaps the cells in your panel are in 3 or 4 series strings and you have a faulty string or 2 in your panel. You can see the effects of shading on a panel in this video. This would be a very similar result if 1 or 2 of the cell strings were faulty. [url]http://youtu.be/UNPJapaZlCU[/url] For your test you could have just shorted the panel leads to give you short circuit current. Just make sure you cover the panel from the sun when making or breaking the connection. Have you thought about mounting a grid type panel on your van? Much cheaper than the fold out 12 volt type you have. [/QUOTE]
