Can we talk about a BASIC UNIVERSAL simple PV kit for preppers.

[Skvez]

There is a large range of things being discussed here.

A radio needs a tiny solar panel because the current demand is small and it's only on for a small part of the day.
The Kettle is only on for a small part of the day but the current demand is HUGE while it's on. I'd recommend you boil water by burning stuff under it, not by using electricity.
Laptop and PC have moderate current draw but you need to give some indication of whether you want it for 30 minutes every other day or 6 hours a day.
The Fridge has a moderate current draw and is typically on for 8 hours a day which means the total power demand is more than a 'small' PV system can support.

I did an article on this back a year ago

You really need to very clearly decide what you want to power before we can recommed the sort of system you'd need.
Unfortunately with solar in the UK in winter you're going to be dissapointed.
