In fact you could raise mushrooms under the solar panels and get triple use of the land.

Building the solar farm on the same location as the windfarm meant 20% could be saved from the construction costs of the solar farm, said Ivor Frischknecht, the chief executive of Arena.
Arena recently commissioned an investigation into the costs and benefits of hybrid solar and windfarms.
It found that besides huge cost savings – achieved mostly because the grid connection was able to be shared by the two generators – the two energy sources were often complementary, producing peak outputs at different times of both the day and year. That meant they combined to create a more reliable energy source.
“Co-location provides more continuous energy generation as windfarms tend to generate more energy overnight whilst solar only generates during the day,” Frischknecht said. “Gullen windfarm generates more power in winter and the new solar farm will generate more in summer.”
