pvl_huld

Huld PV module model.

Contents

Syntax

DCPower = pvl_huld(Module, G, Tm)

Description

Determine the DC power output of PV module from in-plane effective irradiance and module temperature using the following polynomial:

$$P_{DC} = Ee \times (P_{MP0} + k_1 \log(Ee) + k_2 \log^2(Ee)
   + k_3 (T_m - T_0) + k_4 (T_m - T_0) \log(Ee)
   + k_5 (T_m - T_0) \log^2(Ee) + k_6 (T_m - T_0)^2 )$$

The Huld model assumes a reference temperature $T_0$ = 25C.

Inputs

Module contains the following fields:

Outputs

Example

This example shows the use of the Huld model with the generic cSi module parameters listed in [1], Table 7. The coefficients given in [1] are for normalized efficiency, thus $P_{mp0}$ is set to 1.

Module.k = [-0.01724 -0.04047 -0.0047 1.49E-4 1.47E-4 5.0E-6];
Module.Pmp0 = 1;  %
Ee = 1; %suns
Tm = 55; % deg C
Result = pvl_huld(Module, Ee, Tm)
Result =

    0.8635
