Note: Typical specific yield: 1100-1700 kWh/kWp in the US. Performance ratio degrades ~0.5%/year from module aging.

Reference

Specific Yield = Annual Production / Capacity Performance Ratio = Specific Yield / POA Irradiance Capacity Factor = Production / (Capacity × 8760) × 100 Expected PR ≈ 0.82 − 0.005 × (Age − 1)
