Ingolstadt Researchers Develop Game-Changing Matrix for Agrivoltaics Crop Selection
Researchers at the Technical University of Ingolstadt have developed a groundbreaking matrix to select crops for agrivoltaics projects. This tool, based on global solar irradiation data, determines the suitability of plants within different solar resource zones, benefiting water-scarce, arid, and semi-arid regions.
The matrix evaluates 12 crop species, including leafy vegetables, root vegetables, legumes, cereals, and more. It assesses each species' reaction to shading, microclimate changes, and plant growth, considering water demand, shade tolerance, and space requirements. This comprehensive evaluation is based on data from 117 research studies across 25 countries.
The matrix reveals that crops like berries, fruit trees, and vegetables thrive in the microclimates created by solar modules. These crops require less space and offer a higher economic yield per unit area. Conversely, crops such as cereals, fiber plants, and oilseeds need more space and are less suitable for large shaded areas created by increased agrivoltaics installations.
Herbs, grasses, and legumes are particularly well-suited for agrivoltaics projects in water-scarce regions. Future research aims to refine the matrix by incorporating real case studies, empirical field data, and stakeholder contributions to improve its applicability in various agricultural landscapes.
The matrix, developed by researchers at the Technical University of Ingolstadt, is a significant step towards sustainable agriculture and renewable energy integration. It enables farmers and policymakers to make informed decisions about crop selection in agrivoltaics projects, benefiting small agricultural communities, decentralized renewable energy projects, and sustainable rural development.
