Properties

BifacialMismatchLossFactor

The bifacial mismatch loss factor.
This loss factor is applied to the back-irradiance to account for losses due to
the back irradiance being uneven across the module, so causing electrical mismatch.
Positive value implies a loss. A loss is typical.
It is a fraction of 1. i.e. a value of 0.01 implies a 1% loss of back-irradiance.

NOTE: This is only taken into account for bifacial modules and MUST be set when using bifacial modules.

Declaration

public double? BifacialMismatchLossFactor { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

BifacialShadeLossFactor

The bifacial shade factor.
Positive value implies a loss. A loss is typical.
It is a fraction of 1. i.e. a value of 0.01 implies a 1% loss of back-irradiance.
This accounts for that fact that the rear of modules can be shaded by items such as junction boxes
and cables.

NOTE: This is only taken into account for bifacial modules and MUST be set when using bifacial modules.

Declaration

public double? BifacialShadeLossFactor { get; set; }

Property Value

Typically a small value, or zero.

Declaration

public double FrameBottomWidth { get; set; }

Property Value

Type	Description
System.Double

FrameEndWidth

The distance from each end of the rack to the edge of the closest module, in meters.
This distance is considered the same for both ends.
Required for 3D calculations. Not required for 2D calculations.
Typically a small value, or zero.

Declaration

public double? FrameEndWidth { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

FrameTopWidth

The distance from the top edge of the rack to the top edge of the top row of modules on the rack, in meters.
Typically a small value, or zero.
Required for 3D calculations. Not required for 2D calculations.

public double? FrameTopWidth { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

HeightOfLowestEdgeFromGround

The height of the lowest edge of the rack to the ground, in meters.
Required if not a tracker

Declaration

public double? HeightOfLowestEdgeFromGround { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

HeightOfTrackerCenterFromGround

The height of the tracker center from the ground, in meters.
2D ONLY. For 3D models, this information is inferred from the z coordinate in each Tracker.NorthPoint and Tracker.SouthPoint
We assume that the trackers rotate around an axis that goes through
the plane of the modules, and this parameter specifies the height of that axis.

Declaration

public double? HeightOfTrackerCenterFromGround { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

IsBackTracking

Deprecated. Moved to TrackerSystem
Tracker only
If set to true, the tracker system will back-track to avoid row-to-row shading.
Required if tracker

Declaration

public bool? IsBackTracking { get; set; }

Property Value

Type	Description
System.Nullable<System.Boolean>

IsTracker

True implies that this mounting type is a tracker
False implies that this mounting type is a fixed tilt rack

Declaration

public bool IsTracker { get; set; }

Property Value

Type	Description
System.Boolean

MaxRotation

Deprecated. Moved to TrackerSystem
Tracker only
The maximum tracker rotation
Units: degrees
Required if tracker

Declaration

public double? MaxRotation { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

MinRotation

Deprecated. Moved to TrackerSystem
Tracker only
The minimum tracker rotation
Units: degrees
Required if tracker

Declaration

public double? MinRotation { get; set; }

Property Value

Type	Description
System.Nullable<System.Double>

ModulesAreLandscape

True if the modules are mounted on the rack in landscape orientation.
False if the modules are mounted in portrait.

Declaration

public bool ModulesAreLandscape { get; set; }

Property Value

Type	Description
System.Boolean

MonthlySoilingLoss

The irradiance loss ratio due to soiling and snow. One value for each month of the year.
A value would 0.01 would represent a loss of 1%.

Declaration

public ICollection<double> MonthlySoilingLoss { get; set; }

Property Value

Type	Description
System.Collections.Generic.ICollection<System.Double>

NumberOfModulesHigh

How many rows of modules can fit on the rack.

Declaration

public int NumberOfModulesHigh { get; set; }

Property Value

Type	Description
System.Int32

NumberOfModulesLong

How many modules are in each row on the rack.
Required for 3D calculations. Not required for 2D calculations.

Declaration

public int? NumberOfModulesLong { get; set; }

Property Value

Type	Description
System.Nullable<System.Int32>

RackHeight

The total height of the rack, in meters.
This is not the vertical height, but the distance, in the plane of the modules, from the rack bottom edge to the top edge
This is the total measurement of the shading obstacle that the rack represents, so includes the frame.

Declaration

public double RackHeight { get; set; }

Property Value

TransmissionFactor

The transmission factor, or transparency factor.
Positive value implies a gain. A gain is typical.
It is a fraction of 1. i.e. a value of 0.01 implies a 1% gain of back-irradiance
This accounts for the effect that some light passes through the racks and reaches the ground
thereby increasing the ground reflected light that illuminates the back-side of the modules.

NOTE: This is only taken into account for bifacial modules and MUST be set when using bifacial modules.

Declaration

public double? TransmissionFactor { get; set; }

Property Value

Type	Description

If there is just one row in the rack then this parameter is ignored, so can be set to zero.
