The next phase in solar is here. Batteries. Right now we are all almost using "net metering" which requires your solar array to be connected to the electrical grid. Batteries are now good enough to allow us to go off the grid and be energy independent. Living off the grid is a different life style and anyone who wants to do it needs to be very aware of their energy usage, but energy independence is truly real. Batteries will continue to get better and better, but this is a step in the very right direction.
