GIS-based Site Selection for Solar Farms
Research Guide
What is GIS-based Site Selection for Solar Farms?
GIS-based site selection for solar farms integrates geographic information systems with multi-criteria decision analysis to identify optimal locations for utility-scale photovoltaic installations by evaluating solar irradiance, terrain slope, land use, and grid proximity.
Researchers apply GIS tools like ArcGIS alongside methods such as Fuzzy Analytic Hierarchy Process (FAHP) and Boolean-fuzzy logic for suitability mapping. Over 1,000 papers exist on this topic, with key works including Noorollahi et al. (2016, 263 citations) on Iran and Günen (2021, 133 citations) on Turkey. These studies produce raster-based suitability maps prioritizing croplands and low-slope areas (Hassanpour Adeh et al., 2019, 336 citations).
Why It Matters
GIS site selection minimizes land conflicts and transmission costs, enabling faster solar farm deployment; for instance, Yousefi et al. (2018, 137 citations) identified high-potential zones in Iran's Markazi Province, reducing development expenses by 20-30%. In Pakistan, Raza et al. (2023, 92 citations) combined GIS-AHP to select sites balancing solar yield and environmental constraints, supporting 10 GW capacity additions. Choi et al. (2019, 124 citations) reviewed global applications, showing GIS methods accelerate planning for 1 TW-scale PV growth by 2030.
Key Research Challenges
Data Resolution Variability
Solar irradiance and land-use datasets often mismatch in spatial resolution, causing errors in suitability overlays (Choi et al., 2019). Asakereh et al. (2014, 70 citations) noted fuzzy AHP sensitivity to input raster scales in Iran's Shodirwan region. Standardization remains unresolved across global studies.
Multi-Criteria Weighting Bias
Assigning weights to factors like slope versus grid proximity introduces expert subjectivity in AHP and FAHP models (Noorollahi et al., 2016). Günen (2021) highlighted inconsistent hierarchies across Turkish case studies. Validation against built farms is rare.
Dynamic Factor Integration
Climate change alters solar resources and land availability, but static GIS models fail to incorporate temporal dynamics (Hassanpour Adeh et al., 2019). Yousefi et al. (2018) used fuzzy logic for static snapshots only. Real-time grid and policy updates challenge long-term suitability.
