APV-RESOLA Agrivoltaics resource-efficient land use

Research Project APV-RESOLA

Agrivoltaics (APV) is a newly developed system technology which enables agricultural production underneath Photovoltaics ground-mounted power plants (PV-GM) that are especially developed for this purpose. This innovative resource-efficient dual use of arable land could help to mitigate surface sealing and thus ease the conflict between food and energy security. Currently policy-makers protect fertile soils by limiting dissemination of PV-GM. APV widens the scenery of land use options for policy makers by accomplishing the generation of solar electricity without a notable reduction on fertile soils for agricultural production. Further, APV projects are well suited to be realized by farmers, municipalities or small and medium sized enterprises (SMEs). Rural development is being promoted and the added value stays regional. New operational branches for utility and project developers can be identified and income diversification of farmers can be achieved.

To realize these impacts and objectives, the project partners of APV-RESOLA developed a prototype of an APV power plant to explore the technology under real life conditions (Living Lab). The output of PV and photosynthesis is optimized with minimal negative impact on biomass and electricity production while in absolute terms land use efficiency is increased. Finally, the APV-RESOLA research consortium will publish a so-called “Innovation Concept” for the APV technology.

Objectives and impact chain

The project’s primary and secondary objectives are oriented along an impact chain:                                                                                    Input->Output->Outcome->Impact

On the input-level, different work packages, like the development of a lightning protection, contribute to a special output, which in this case would be the finalization of the work focus “Technology”. Research is conducted in five work focus groups: “Technology”, “Environment and Biodiversity”, “Energy Economy”, “Agriculture” and “Society”. The Outcome is the collective result of the outputs of all five focus groups: A market-ready APV plant for the use on agricultural land. The primary objective is a maximum Impact on a resource-efficient land use in Germany and thereby mitigating land-use conflicts between food and energy security. The maximum Impact is ought to be realized by the combination of the market-ready APV technology and the accompanying political and social innovations, like new concepts for approval procedures on a municipal level or adapted processes in agricultural management. Currently there is no public regulation or funding for APV-Technologies, which is indispensable for Renewable Energy Technologies (also for common PV-GM or Wind-Power or Biogas plants). Therefore, the Innovation Group APV-RESOLA advocates a so-called “Level-Playing-Field”, in which every technology has the same chance on market launch and further development. The publication of an APV-Innovation concept that illustrates a way to disseminate the APV technology is therefore an important part of our primary objective (Impact).

Project status

After the ceremonial inauguration of the APV research plant in Heggelbach the scientific focus is now on the agricultural measurements and analysis.
