While its true that an assembly plant might have less personal electronics per person, some of the large automation equipment can easily draw kilowatts of power! Even a simple robot arm has several motors, each powered by a few hundred volts and drawing a large current as well. It is difficult for solar panels to provide this enormous current draw (although having 80,000 of them would definitely alleviate some of this). Is there any data for how this makes sense for GM economically, i.e.: price per watt for solar vs. simply buying it from the grid? How is Spain's nuclear power capability? Their neighbour to the north, France, is largely powered by nuclear plants. If this is the case in spain as well, the carbon reduction would be minimal at best.

I wonder if this technique can be used to differentiate between exposed axons and those surrounded by white matter? Some recent research has shown that such connections can play very different roles in brain organization and memory. This mapping technique definitely seems like a step in the right direction, now we need to figure out how to colour code the wires!
