Where:

E₁ = First E interpolation term between 600 V and 2700 V (J/cm²)
E₂ = Second E interpolation term used when Voc is greater than 2700 V (J/cm²)
E₃ = Third E interpolation term used when Voc is less than 2700 V (J/cm²)
E₆₀₀ = incident energy at Voc = 600 V (J/cm²)
E₂₇₀₀ = Incident energy at Voc = 2700 V (J/cm²)
E₁₄₃₀₀ = Iincident energy at Voc = 14,300 V (J/cm²)
E _≤600 = Incident energy for Voc ≤ 600 V (J/cm²)
VOC = System open-circuit voltage (kV)
