Admittedly we are very conservative with usage but I do spend a couple hours reading with one or two LED lights burning and the propane fridge does use some 12 Volt, plus the water pump. When I did the install added an outside plug so that I could add an additional panel if needed but that now seems unlikely.. I am more that pleased.
Congrats! Solar sure is nice to have to just keep the battery(s) getting some charge on most days. You can't beat the silence they generate also
PS: If you ever needed another panel for that outside plug, just find a used one with similar specs/voltages on craigslist or FB Marketplace or Nextdoor. I found several 100w 12v panels for an upcoming install for $25 each (...tested them each prior to purchasing). Just for kicks, I even recently created a simple portable 100w system that I could leave on my boat when it is stored to keep the two 12v deepcycle batteries topped off. I recently let my neighbor with a pop-up trailer use that portable system when they went camping and they loved it...
