System.Double |
EnergyYield
The monthly of annual mean array yield, as defined by IEC 61724, Section 8.4.4
From IEC 61724:
"This yield represents the number of hours per [month or year] that the array would need to operate at its
rated output power P_0 to contribute the same [monthly or yearly] array energy to the system as was monitored."
Units: hours
Declaration
public double EnergyYield { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
GainOnTiltedPlane
The gain on tilted plane
Fraction of 1.
0.01 represents a gain of 1%
Declaration
public double GainOnTiltedPlane { get; set; }
Property Value

---|---|
System.Double |
Ghi
The annual or monthly energy per unit area associated with the GHI
Units: kWh/m²
Declaration
public double Ghi { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
Gi
The annual or monthly energy per unit area associated with the global irradiance in the plane of the array
If not all the modules are in the same plane then this is an average weighted by the module areas.
Units: kWh/m²
Declaration
public double Gi { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
GiWithHorizon
The annual or monthly energy per unit area associated with the global irradiance, incident on the plane of array, with horizon losses included.
If not all the modules are in the same plane then this is an average weighted by the module areas.
Units: hWh/m²
Declaration
public double GiWithHorizon { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
GlobalEffectiveIrradiance
The annual or monthly energy per unit area associated with the global effective irradiance,
the incident irradiance after losses are taken into account.
The incident irradiance may not be uniform over the plant, due to shading losses, or simply module being in different planes.
This is therefore an average weighted by the module areas.
Units: kWh/m²
Declaration
public double GlobalEffectiveIrradiance { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
ModulePower
The annual or monthly energy derived from summing the modeled MPP for each module
This takes no account of electrical mismatch or inverter effects
Units: kWh
Declaration
public double ModulePower { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
ModulePowerAtSTC
The annual or monthly energy derived from multiplying the effective irradiance by the modeled module efficiency at STC
The modeled module efficiency is calculated using the diode model, including the modeling correction factor
This takes no account of electrical mismatch or inverter effects
Units: kWh
Declaration
public double ModulePowerAtSTC { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
NetEnergy
The net energy, in MWh
Currently this is the same as PAC as there is no model of AC losses in SF-Core
Units: MWh
Declaration
public double NetEnergy { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
NominalEnergy
The annual or monthly energy derived from multiplying the effective irradiance by the nominal module efficiency at STC
The nominal module efficiency is taken from directly from the Pan file
This takes no account of electrical mismatch or inverter effects
Units: kWh
Declaration
public double NominalEnergy { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
Pac
The annual or monthly energy derived from the modeled AC power
This is the power exported by the inverters, so is before
the AC wiring loss or transformer loss.
Units: kWh
Declaration
public double Pac { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
Pdc
The annual or monthly energy derived from the modeled DC power
This uses the DC power before any corrections are made for operating limits of the inverters.
The real DC power will be lower if the MPP trackers cannot follow the true maximum power points due to voltage, current or power output constraints.
Units: kWh
Declaration
public double Pdc { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
PercentComplete
The percentage of the period (year or month) that was covered by the simulation
Declaration
public double PercentComplete { get; set; }
Property Value
Type | Description |
---|---|
System.Double |
PerformanceRatio
The performance ratio
A non-dimentional number that represents the total efficiency fraction of the plant.
It includes all effects except the gain from tilt and the nominal efficiency of the modules.
