pvl_sapmcelltemp

Estimate cell temperature from irradiance, windspeed, ambient temperature, and SAPM module parameters.

Contents

Syntax

Tcell = pvl_sapmcelltemp(E, E0, a, b, windspeed, Tamb, deltaT)

[Tcell Tmodule] = pvl_sapmcelltemp(E, E0, a, b, windspeed, Tamb, deltaT)

Description

Estimate cell and module temperatures using the Sandia Array Performance Model (SAPM) [1], when given the incident irradiance, wind speed, and ambient temperature.

The cell temperature model is

$$T_c = T_m + {\frac{E}{E_0}} \Delta T $$

$$T_m = E \left( \exp \left( a + b W \right) \right) + T_a $$

Example

Calculate cell temperature for a typical glass/cell/polymer sheet module mounted on an open rack. a, b, and deltaT parameter from [1], Table 1. Sample weather conditions are used.

deltaT = 3;
a = -3.56;
b = -0.075;
E = 800; % Incident irradiance
E0 = 1000;
windspeed = 5; %5 m/s
Tamb = 10; %10 deg C
Tcell = pvl_sapmcelltemp(E, E0, a, b, windspeed, Tamb, deltaT)
Tcell =
