I modified a chest freezer to utilize as a refrigerator. I use less than 150w per day on it, although the starting load is somewhat higher, on my system it is not a problem. Cold air sinks - stand up refrigerators are horribly inefficient whether propane or electric.

They beat trying to store ice form a lake all season.

Watts per day is a nonsensical measure.
