> I joked with my neighbour that we should wire up our homes and sell my excess to him at mid point and we would both be better off.
I've been looking at this but not as a joke and you run into some fairly interesting problems when you start paralleling after the meter. Long story short: don't do this unless you have a lot of electrical engineering chops or you might end up create a liability in case of a leak to ground or an overcurrent situation. This needs some special handling. The best way would be to just create an extra circuit and use a waterproof extension cord to power it, that way all GFPs see their real current and not a fraction of it and you can't accidentally feed into a distribution panel at more current than the breakers see, which is an excellent way to start a fire.
