Now where shall I start ?. In order of priority.
First on the list, like MB, a smallish solar setup, about 2kw, panels, controller, battery bank, inverter and all wiring, will cost about £2,000 to £2,500.
Another shed, with a good solid floor, i would put two ibc’s in it, water problems solved permanently, and out of sight, and room for more storage shelving, all up about £800.
A new genny, diesel preferably due easier fuel storage and the number of places and businesses i could scavenge from. I have an old honda petrol genny i bought second hand four months ago (cost me £50) but a nice new shiny one would be good.
A better greenhouse would also be useful as would a couple of electric bikes or mopeds, or even a very old EMP proof diesel 4x4 (just to boast i’ve got one)
