Forget watts. Look at ampere rating. Isc is short circuit rating and that is what you will get on a clear day tilted at the sun.
Here is a 120 watt panel that provides 7.5 Isc amps for comparison.
Solar Cynergy 120 Watt 12 Volt Solar Panel
You may get full rating about 3 hours per day ramping up in the morning and down as the sun sets. This would be about right for a single battery and moderate use. You should also get a controller.
