MeteorologicalConditionsDataset then the year is set there and
this parameter has no effect.
Optional. Default: 1990

Declaration

public int CalculationYear { get; set; }

Property Value

Type	Description
System.Int32

ConnectorResistanceBinWidth

The bin width to use for the connector resistance.
This is required because the connector resistance is defined per layout
so if we are considering whether two modules from different layout
are in-fact in equivalent operating conditions we need to compare the
connector resistance.

Property Value

Type	Description
System.Nullable<System.Double>

Property Value

Type	Description
System.Boolean

IncludeCellTemperatureModel

If false, the cell temperature model will be disabled.
This does not disable the effect of cell temperature on the calculation of the module performance using the one diode model.

Property Value

Type	Description
System.Boolean

Property Value

Type	Description
System.Boolean

IncludeSoilingLossInTemperatureModel

If true the irradiance input to the cell temperature model will include the soiling loss.
This setting is related to UseIAMForTemperatureModel, but independent. In combination these two flags create 4 options.
The spectral model is never applied, and back-side irradiance is not included in the temperature model.
Near and far shading are always included in the temperature model.

Optional. Default is true.

Declaration

public bool ModelBackRowSeparately { get; set; }

Property Value

Type	Description
System.Boolean

are in-fact in equivalent operating conditions we need to compare the module
mismatch loss.
