i just bought a 15 watt panel for 75.00 i think i will try it and see how many hours i get. the bug slugger says it draws 6.5 amps so i might end up using 2-15 watt panels.6.5A*12v=78W so with 2-15 watt panels i would see at least 2-2.5 hours that would probably be enough for me.

You can pay more but you cant buy better.
