It would require about 31 hectares of corn ethanol to produce the same amount of energy generated by 1 ha of solar panels (www.anthropocenemagazine.org)

From wikipedia:

Figures compiled in a 2007 report by National Geographic[70] point to modest results for corn ethanol produced in the US: one unit of fossil-fuel energy is required to create 1.3 energy units from the resulting ethanol

Add on top of that the environmental impact and opportunity cost of the land use, and corn based ethanol becomes a non-viable solution.
