I see a lot of comments about needing electricity to do X so that's no good after SHTF, I would have thought going solar was one of the first things to do for a prepper although I admit you can't eat a solar panel
Also I guess if you live in an apartment there's nowhere to put the panels so that's a problem.
I've been living on solar for 15 years and I do just about everything people on-grid do, that said I am starting to collect manual tools because like any modern tech my solar may fail and I may not be able to fix it, but I do have redundant systems and for low power use you could easily have 2-3 spare inverters and chargers to cover failures. I guess long term (say 10 years) the batteries will fail and then you are stuck so if things haven't been restored you had better have weaned yourself off power by then.
I'm also interested in aquaponics, but AFAIK that requires measuring of Ph etc and pumps to circulate water, how will that be done with no power and no supply of Ph measuring strips? And what sustainable source of fish food is there? Not trying to be smart, I want to know this.
Anyway just wonderin', I agree that aiming to live without power at all is a worthy goal, so maybe it's really a matter of how long you think STHF will last and taking a gamble on that.
