The sun shines over a field and through the cells of a solar power plant in Herdwangen, Germany, 24 April 2017. Scientists from the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg and from the University of Hohenheim in Stuttgart installed this pilot project's plant. Grains and vegetables are to be cultivated in the field while the solar system generates electricity. Photo: Patrick Seeger/dpa/Patrick Seeger /MediaPunch ***FOR USA ONLY***
