Innovation – Photovoltaics

Agri-PV combines solar modules with agricultural land use. Picture this: solar panels above, crops below. Forschungszentrum Jülich is testing this innovative concept with demonstration installations in the Rhineland region.

Matthias Meier-Grüll, how does it work?

Meier-Grüll: Researchers are experimenting with three distinct Agri-PV systems. The first involves vertically fixed solar modules on a framework, leaving ample space for farm machinery. The second variant uses a tracking system, allowing the modules to follow the sun's trajectory.

Meier-Grüll: What sets the third method apart? Elevated structures akin to pergolas, with PV modules mounted on top, enabling plants to grow underneath. This setup is ideal for crops that thrive in shaded or rain-sensitive conditions.

What are the benefits of Agri-PV?

Meier-Grüll: The dual use of land presents numerous benefits. By optimizing land for solar power generation, Agri-PV can make a substantial impact on the energy transition. Meanwhile, agricultural yields remain stable or even improve. Solar roofs provide plant protection, and reduced evaporation due to shading cuts water consumption.

What are the challenges ahead?

Meier-Grüll: Despite the promising progress, challenges persist. The German government has acknowledged the potential of Agri-PV, enhancing conditions through a 2023 amendment to the Renewable Energy Act (EEG), which includes financial incentives. Nevertheless, complicated building permit procedures still hinder swift expansion. Additional measures are needed to accelerate development.
