> If you consider e.g. organic solar panels mass produced using some inkjet style production process, producing many TWH of solar capability might become a matter of just printing such panels by the square mile using cheap production processes that don't involve a lot of exotic materials, energy, etc.

If the panels are too cheap, the cost of the inverter becomes the bottleneck. That is, there's a limit to how low you can go; even if the panels cost zero to produce, you still have to produce the inverters.
