12 volt TV

I am looking for a way to watch Football during an upcoming dry camping trip. If I buy a 12 volt LED tv will it kill my battery if it's on a lot of Sunday? I have the solar panel. Also when I camp with hook ups, will the 12 volt tv run from the battery or does it connect to the electrical hook up? Or can I buy a converter to convert the 12 volt to a regular plug and hook up a regular tv? What's the best option? I don't really want to buy a generator and I don't anticipating dry camping very frequently.
