Hi
What makes panels work with your 12 volt system is the controller. High voltage panels require an MPPT controller and they are a premium price (for 8% more solar harvest).
Here is a 140 watt panel for $154. http://www.solarblvd.com/p2582/Solar-Cynergy-140-Watt-12-Volt-Solar-Panel/product_info.html?osCsid=0765826af670ba33d03682b08b25d3a7
Get two of those with a decent PWM controller.
Here is a link to a panel @ $174: 235 watt 24 volt 0.74 cents per watt
This option requires an MPPT controller.
