The German government's goal of achieving climate neutrality by 2045 and increasing the use renewable energy, particularly wind solar power, has public support. However, local siting farms is highly controversial due to land-use conflicts. We have developed a comprehensive Geographic Information System (GIS) model that integrates criteria from literature identify optimal locations for ground-mounted photovoltaic (GM-PV). based on holistic approach considering energy-related factors broader environmental considerations. It ensures shift in land food energy production consistent with economic realities both agricultural sectors. unique feature its integration socio-technical criteria, including novel dual benefit protecting erosion-prone soils conserving soil carbon areas prone organic matter decomposition associated CO2 release. Our multi-criteria GM-PV includes 12 restrictions five suitability representing key aspects. Scenario analysis highlights sensitivity Germany's potential defined criteria. In 1, minimal constraint, 14.2 % available GM-PV, decreasing 1.9 constrained 12. Suitable (>10 ha) account 0.4 area, which could cover 8.1 electricity consumption restricted scenario. spatial distribution results show innovative changes preference such as radiation south storage north Germany. Assuming plant size will become more critical realise economies scale future, significantly influences visual impact landscape. application restriction reduces Germany but also pitfalls decision-makers. GIS can be applied regional contexts integrate stakeholder values generate region-specific scenarios, thresholds easily adapted characteristics, preferences, concerns, those related agriculture, biodiversity, societal acceptance.
