Farm Performance

Performance Metrics Explained

• PR: Performance Ratio
  Represents how efficiently the farm converts sunlight into usable power compared to its theoretical maximum.
  Formula: ∑[P_AC(t) × Δt] ÷ (P_rated × ∑[G_POA(t) × Δt] / G_STC)
• Power Output:
  The actual energy generated in kWh
• % Difference:
  Percentage Difference between farm and PVSyst
  A positive value means the farm outperformed the PVSyst prediction.
• Availability:
  Farm uptime percentage
  The proportion of time the farm was operational and generating power. Calculated as total possible generation vs curtailed time.
