Calculation method

Calculation method

Bifacial scenario total energy (kWh)

Front energy × (1+rear gain) × (1−additional losses); all gain factors supplied, no irradiance geometry model.

Increment relative to front energy (kWh)

Front energy × (1+rear gain) × (1−additional losses); all gain factors supplied, no irradiance geometry model.

Symbols and units
a

c
Additional bifacial losses (%)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Front energy × (1+rear gain) × (1−additional losses); all gain factors supplied, no irradiance geometry model. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
