But it isn't anywhere what it needs to be to replace the current transportation/heating/industry demands, and it would be very very very costly to do that. Most cars run on fuel, you need to send ALL that power plus inefficiencys over the grid and replace gas heating and industrial energy consumption, and have the solar capacity to back it up.
Also "grid parity" is a strange metric, are you going to replace farmland with solar panels during the buildout to meet the energy demands?
