Ok... I just made myself chuckle by reading your response. Well... bulk buying is a great way to save money that can go towards other key equipment. But... if you were thinking of using it for long term meat storage.... you need to ensure that you have a way to power it if the power goes out or you will lose anything in it.
True... or a wind generation system... but those are usually visible to the starving public. And... solar only works efficiently with sun. So... if you have long winter weeks of overcast weather... your solar won't help you and your batteries will die out. You may want to consider a sizeable battery storage system big enough that it will run your freezer for 4-6 hours each day for about a week to ensure you keep things frozen. If you grab what you need... and then run the 4-6 hour cycle... you should keep things frozen.
