Well, if you want to rely on solar, especially when there is a grid down, think the Moultonboro weather problems, and you want to supply the town with this array, you still need night time storage. Obama/FLL invested massive amounts of $$ into this:

Don't get me wrong, one of my assets runs on solar/batteries, has been for 35 years, it is just yet approaching prime time.
As far as grounding, do a little research, and tap (googles... sigh) "knowledge" if you need to. Then, perhaps, you can build up your side of the story.
