State-Wise Solar Resource & Expected Yield

Solar resource and expected generation for every Indian state and union territory. Specific yield is computed from average peak sun hours at a 78% performance ratio — the realistic figure for a well-built Indian rooftop, not a datasheet maximum.

Sources

  • Peak sun hour values derived from long-term solar resource datasets (NASA-SSE / NREL class data) for representative locations in each state.
  • DISCOM listings compiled from state distribution utility records.

How to Read This Data

  • Specific yield = PSH × 365 × 0.78 performance ratio. Real output varies with tilt, shading, soiling, and module technology.
  • Values are state-level averages; large states span meaningful internal variation. Use site coordinates in the tilt and yield calculators for project-level figures.
  • Verify DISCOM jurisdiction for your specific connection — several states have multiple licensees including private distributors.
