Namespace: SolarFarmerApi.Client

Syntax

public class EnergyYieldResults

Properties

AverageTemperature

The average ambient temperature in degrees Celsius.

Declaration

public double AverageTemperature { get; set; }

Property Value

Type	Description
System.Double

EnergyYield

The monthly or annual mean array energy yield, as defined by IEC 61724-1:2021.
The array energy output (DC) per rated kW (DC) of installed PV array.
Units: kWh/kWp

Declaration

public double EnergyYield { get; set; }

Property Value

Type	Description
System.Double

GainOnTiltedPlane

The gain on tilted plane from the horizontal.
Fraction of 1.
0.01 represents a gain of 1%

Declaration

public double GainOnTiltedPlane { get; set; }

Property Value

Type	Description
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: kWh/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, injected into the grid.
It includes the AC collection losses (AC collectors, transformers), and grid connection and availability effects.
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 dimensionless number representing the global efficiency of the plant. Expressed as a fraction of 1.
It includes all effects except the gain from tilt and the nominal efficiency of the modules.

Declaration

public double PerformanceRatio { get; set; }

Property Value

Type	Description
System.Double

PerformanceRatioBifacial

The bifacial performance ratio.
A dimensionless number representing the global efficiency of the bifacial plant. Expressed as a fraction of 1.
Similarly to the performance ratio (PR), the bifacial PR includes all effects except the gain from tilt and
the nominal efficiency of the modules. It is estimated as defined by standard IEC 61724-1:2021, where a
bifacial irradiance factor is introduced to correct the measured irradiance terms.
The PR and bifacial PR are the same for monofacial projects.

public double PerformanceRatioBifacial { get; set; }

Property Value

Type	Description
System.Double
