Gertrude Said:

Can a small fridge be powered 24/7 by being covered in solar panels?

We Answered:

This sounds impractical, considering the way normal refrigerators are opened and closed many times a day.

There are excellent insulating materials today, and it is possible to build a refrigerator-sized box that will keep ice solid for a month with no energy input at all, in shirtsleeve weather. All one would need to do is hook up a small cooling unit to such a box, and eventually it would reach refrigerator temperatures. That cooling unit could be powered by solar panels, and only a few hours a day. The problem is, once someone opened the door, it would take a long, long time to cool down again.
