8 hours, to deliver shall we say 40ah, thats 5a/hour x 8. So you need a panel that can deliver 5A@14V. You're lucky to have the sun as a resource !

Here are a couple of options.
Buy this panel new for about $80.
http://www.amazon.com/10W-5A-Controller-Regulator-Charger/dp/B009XY61Z2
Or get the same panel used off ebay for $17
http://www.ebay.com/itm/10-Watt-Solar-Panel-10W-12V-5A-Solar-Controller-Regulator-Charger-/230763702394
It's rated for 10W 12V@5A but the output will vary from 10V to 17V.
