What is the Amp hour (Ah) rating of your battery? One battery? When you say you get 3 days out of your battery, what is the battery voltage before starting the charging process (TV charging on the way back home)?
I normally do not recommend any SOLAR panels less than 100 watts, as you only have a max of 5 good hours of sunshine each day, providing the panels are out in the sun. So, if you had a 50 watt panel, 5 hours of sun would only put about 20 Ah, back into your batteries each sunny day. That does account for any cell phone , tablet or radio playing. A 100 watts will at least give you a fighting chance to charge the battery. 100 watts of SOLAR, 5 hours of sun would put about 40 Ah back into your battery each sunny day. The one thing to remember is your battery voltage should never go below 12VDC, or it will shorten your batteries life.
Take a look at the Renogy 100 watt SOLAR kit on Amazon or the Renogy website.
