Electricity needs when the grids down.

[Pete Grey]

Yes BP a solar set up will not last for ever, but panels will last 20+ years during which time yes the efficiency will decrease. The lead acid batteries we are used to may only last 5 or 6 years but lithium batteries can recharged 2000+ times, and you can always have a spare charge controller.

However........Everyone has to decide what they want within practical limitations, solar off grid will not do everything we would wish for, even if you were to spend £1000’s.

We have decided that our needs are just to charge AA and AAA batteries for torches, our LED lamps, walkie-talkies, a SW radio for news, and a few power tools for home maintenance. This is affordable and would make life much easier come SHTF. I would not like to rely on candles and oil lamps for lighting even though we have them for back up.

You pay your money and you make your choice.
