## 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:

The Huld model assumes a reference temperature = 25C.

## Inputs

- `Module` - A struct defining the parameters for the module.

`Module` contains the following fields:

- `Module.k` - A 1x6 vector with the coefficients through .
- `Module.Pmp0` - Power at STC reference condition (W).
- `Ee` - The effective irradiance incident upon the module (suns).
- `Tm` - The module temperature (degrees C).

## Outputs

- `DCPower` - A vector containing the Pmp for each input Ee and Tm.

## 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 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
