Potential of Solar PV in Tamil Nadu
The re-categorized layers were then overlaid to arrive at the common overlapping area, which was thereafter overlaid with permanent exclusions (land not available for development) and all common areas were removed from final consideration. In addition, areas with contiguous land area of less than five acres (0.02 sq. km), representing a minimum of 1 MW solar PV plant capacity were excluded. The remaining area was assumed as area available for solar PV development and was multiplied by the solar PV density function of 50 MW/sq. km to arrive at wasteland-based solar PV potential of Tamil Nadu.
