It isn't the power rating of the freezer because that will be in watts or amps. If the freezer is a normal home one 110/220 volts AC you will need an "inverter" because a panel will produce 12v or 24v DC. The problem with a fridge or a freezer is that they need a huge amount of power for a few seconds each time the compressor switches on.
In my opinion, green living does without a freezer altogether, food for winter is stored in jars, cans or is dried.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
