Note: Specific yield of 1200-1800 kWh/kWp is typical in the US. First-year degradation (LID) is 1-3% for crystalline silicon.

Reference

Annual POA = Peak Sun Hours × 365 Gross Yield = Capacity × Annual POA × Performance Ratio Annual Yield = Gross × (1 − Degradation%) Specific Yield = Annual Yield / Capacity Performance Ratio typically 0.75-0.85
