We already devote really significant amounts of land to energy in the form of corn for ethanol, ~10% of total US cropland. Corn only captures 1% of incoming light vs ~20% for PV solar, so it would be a huge gain in land efficiency to replace corn ethanol with an energy equivalent amount of PV.

This is a result of corn subsidies, not a naturally economically efficient land use.

That's a good point. The amount of resources we waste on bioethanol are huge.
