The Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg has been working on the topic of agricultural photovoltaics for some time. Max Trommsdorff heads the research there. In his eyes, their time has come, "faster than expected".
Trommsdorff sees Agri-PV as "a technology that has the potential to reduce water consumption and make land use much more efficient". A lot is happening in materials research: There is, for example, increased interest in organic PV films or thin-film PV, which precisely allow the light spectra required by the respective plants to pass through. "There is also a trend towards so-called bifacial PV systems, the rear of which is also electrically active," says Trommsdorff. This results in a higher electricity yield per square meter of module area.
In practice, however, it is not only good scientific arguments that decide whether it is enforced, but above all business management. Farmers now have clarity: the EU agricultural subsidy continues to exist if there is "main agricultural use", i.e. no more than 15 percent of the usual yield is lost through the solar systems. However, there are still no clear criteria for animal husbandry.
