2010 Salem Cruise Lite - Solar panels

[wifeytojosh]

Hi,


I am new to this forum. We have a 2010 Salem Cruise Lite. It is 20ft. We have never dry camped before and I would like to get our family to the beach where most rv campgrounds don't have hook-ups. How many solar panels would I need to keep the electricity going from the battery while we are away? I don't need the a/c, just lights and plugs. Maybe the radio too. Any info would be helpful. Thanks.
