Is it really worth having and hooking up to the grid???
First is the cost of equipment to do so and then you have the cost of an electrician and I read someplace
that this person is hooked up to the grid with solar he
pays 17 cents for grid power and any excess that he
sends back he gets 3 cents that's 14 cents difference

Depends on location and power company, I sell mine back for the exact rate I purchase for.
Therefore a battery system makes zero sense for me. Negative payback period.
For some more complex situations, stored power sold back during peak demand times can pencil out pretty nice with batteries.
For some situations, the sell back rate is a fraction of the purchase rate (which I think is BS)
