For $1,300 one could buy the JouleBox 1000 kit which ticks most of the boxes to get us off grid. I know this is a lot for people but it can't be more than what they pay in just one year from the grid. Whereas these kits are guaranteed for 25 years with smash proof and water proof bulbs ;)
The only thing missing from this particular kit is a fridge!
I will find out how long the panels & batteries on this UK site are supposed to last. That is a good question worth finding the answer to.
