How many amps does a 50 watt produce, 80 watt, 120 watt?

Depends how they're connected. Many panels in parallell produce a high current and lower voltage and in series its the other way round. I think one on its own tends to have a high voltage and lower current. I don't know the formula for watts to amps though sorry.

The solar panels you are pointing out are what is called 12 volt panels and are normally about 17.2 volts so 50 watts divided by 17.2 is 2.9 amps.
You have to have higher voltage then the battery. If you had a 12 volt panel you could never charge a 12 volt battery (12.6 volts is full charge).
So you lose the voltage and amps / wattage above what you use unless you have an MPPT charge controller which down converts the voltage.
There is a lot more to it then that, But you get the idea.

It depends on the voltage. Most solar panels operate at 24 volts. You already know the relationship between volts-amps-wattage.
