Speaking of refrigeration, what kind of portable solar-battery charger setup could run a small fridge in the summer?

A lot of RVs owners are using solar setups to power at least some of their needs. I'll start looking for those setups when we go camping in the next couple weeks. Would like to discuss them with some owners.

If I were dealing with a chronic health condition requiring refrigeration for medicine this is an area I'd be looking very seriously at. And since that day may arrive I'll look seriously at it anyway.
