Function sapm_module 

pub fn sapm_module(
    poa_global: f64,
    temp_air: f64,
    wind_speed: f64,
    a: f64,
    b: f64,
) -> f64

SAPM module back-surface temperature model.

T_module = poa_global * exp(a + b * wind_speed) + temp_air

Arguments

• poa_global - Total incident irradiance [W/m^2].
• temp_air - Ambient dry bulb temperature [C].
• wind_speed - Wind speed at 10m height [m/s].
• a - SAPM parameter a (default -3.56 for glass/polymer open rack).
• b - SAPM parameter b (default -0.0750 for glass/polymer open rack).

Returns

Module back-surface temperature in Celsius.
