It's not a great value proposition currently, in 5 years extrapolated it will. In 10 years solar and batteries will likely be 2x cheaper than we have now. At that point every other form of electricity generation will make no financial sense.

I'm not sure of that...but even then, it will always be cheaper to do grid scale solar and batteries, as opposed to indivdual units replicating all the controllers and such, plus the much higher install costs and installation compromises due to not being able to optimize placement. Land use is the biggest issue, but I'm sure there is enough around here to handle it.
