Query: Solar power rules

I was advised to purchase this size solar panel by a friend so I could keep my RV deepcycle battery from discharging. The second day camping , I set up the solar panel on top of mycamper shell and hooked it up to my trailer battery. By 11:00 am the battery was fully charged.The only thing I added was some insulated electrical connectors from Home Depot. The solarpanel works great, I no longer need to be concerned about saving power to make the battery last.I have plenty of power to last however long I stay.BigJAY
