Roughly 50% of germany is used as farmland. On 60% of the farmland crops to feed livestock are grown. On 20% of it crops for energyproduction (biofuel, biogas).
If you take for example rapeseeds, used for biodiesel, you would harvest around 50 times as much energy with a pv-plant on the same area.
You would need to install pv on 5-6% of the farmland to produce enough electric energy for all of germany for a year. Granted you also can provide the grid for it and enoguh storage.
