solar power – Least amount of space for running one applicance without electric grid? – GWC Mag

I’ve posted several questions related to this topic, but they seem to cover too much. So I’m trying to be more specific.

I have a regular fridge, and when I connected a power meter to it for 24 hours, it read 1.83KWh.

I live in an apartment with a limited open area.

Question: what’s the least amount of space needed to run this fridge without using the power grid? I’ve heard that there are more compact power sources than solar panels, but I have no idea how to search for the info. Also, I won’t be changing the fridge.

I posted a similar question a few months and someone replied, which I really appreciated. Unfortunately, the member’s answer assumed that “Grid power is incredibly cheap” and that’s incorrect. In my country, grid power is very expensive and incredibly unstable.
