B3_G0-class: Class "G0": irradiation and irradiance on the horizontal plane.

Description

This class contains the global, diffuse and direct irradiation and irradiance on the horizontal plane, and ambient temperature.

Objects from the Class

Objects can be created by the function calcG0.

Slots

G0D:

Object of class "zoo" created by fCompD. It includes daily values of:

Fd:

numeric, the diffuse fraction

Ktd:

numeric, the clearness index

G0d:

numeric, the global irradiation on a horizontal surface (Wh/m²)

D0d:

numeric, the diffuse irradiation on a horizontal surface (Wh/m²)

B0d:

numeric, the direct irradiation on a horizontal surface (Wh/m²)

G0I:

Object of class "zoo" created by fCompI. It includes values of:

kt:

numeric, clearness index

G0:

numeric, global irradiance on a horizontal surface, (W/m²)

D0:

numeric, diffuse irradiance on a horizontal surface, (W/m²)

B0:

numeric, direct irradiance on a horizontal surface, (W/m²)

G0dm:

Object of class "zoo" with monthly mean values of daily irradiation.

G0y:

Object of class "zoo" with yearly sums of irradiation.

Ta:

Object of class "zoo" with intradaily ambient temperature values.

Besides, this class contains the slots from the Sol and Meteo classes.

Extends

Class "Meteo", directly. Class "Sol", directly.
