GIS (Geographic Information Systems) is crucial for solar plants, enabling optimal site selection by layering data on solar radiation, infrastructure, land use, and environmental factors to find the most viable, efficient, and sustainable locations, while also assisting in design, impact analysis, and ongoing operations. It streamlines complex spatial decisions, reducing risks and costs by identifying suitable areas for high energy output while avoiding sensitive zones, ensuring compliance, and optimizing grid connection.
Key Significances of GIS in Solar Plants:
Site Selection: GIS integrates data (slope, solar irradiance, proximity to roads, power lines, urban areas) to identify ideal locations, using techniques like Multi-Criteria Decision Analysis (MCDA) and Analytical Hierarchy Process (AHP).
Environmental Impact Analysis: Helps identify sensitive habitats, protected lands, or cultural sites to minimize ecological damage and ensure regulatory compliance, as noted by Enhar and KERAMIDA Inc..
Resource Assessment: Maps and quantifies solar potential (Global Horizontal Irradiance) over large areas, revealing high-potential regions for development, according to work by the Indian Institute of Science.
Infrastructure Planning: Optimizes plant layout, determines best routes for transmission lines, and assesses proximity to existing substations for efficient interconnection, say TRC Companies and Enel Green Power.
Design & Optimization: Aids in designing optimal panel orientation and site layout, minimizing shading and maximizing energy production, notes ScienceDirect.com.
Risk Mitigation: Identifies areas prone to erosion or damage, helping plan best practices for construction and operation.
Stakeholder Communication: Provides data-backed visuals for landowners and authorities, facilitating project approval and discussions, as described by Enhar.
