B4_Gef-class {solaR}R Documentation

Class "Gef": irradiation and irradiance on the generator 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 calcGef.

Slots

GefI:

Object of class "zoo" created by fInclin. It contains these components:

Bo:

Extra-atmospheric irradiance on the inclined surface (W/m²)

Bn:

Direct normal irradiance (W/m²)

G, B, D, Di, Dc, R:

Global, direct, diffuse (total, isotropic and anisotropic) and albedo irradiance incident on an inclined surface (W/m²)

Gef, Bef, Def, Dief, Dcef, Ref:

Effective global, direct, diffuse (total, isotropic and anisotropic) and albedo irradiance incident on an inclined surface (W/m²)

FTb, FTd, FTr:

Factor of angular losses for the direct, diffuse and albedo components

GefD:

Object of class "zoo" with daily values of global, diffuse and direct irradiation.

Gefdm:

Object of class "zoo" with monthly means of daily global, diffuse and direct irradiation.

Gefy:

Object of class "zoo" with yearly sums of global, diffuse and direct irradiation.

Theta:

Object of class "zoo" created by fTheta. It contains these components:

Beta:

numeric, inclination angle of the surface (radians). When modeTrk='fixed' it is the value of the argument beta converted from degreesto radians.

Alfa:

numeric, azimuth angle of the surface (radians). When modeTrk='fixed' it is the value of the argument alfa converted from degrees to radians.

cosTheta:

numeric, cosine of the incidence angle of the solar irradiance on the surface

iS:

numeric, degree of dirtiness.

alb:

numeric, albedo reflection coefficient.

modeTrk:

character, mode of tracking.

modeShd:

character, mode of shadows.

angGen:

A list with the values of alfa, beta and betaLim.

struct:

A list with the dimensions of the structure.

distances:

A data.frame with the distances between structures.

Extends

Class "G0", directly. Class "Meteo", by class "G0", distance 2. Class "Sol", by class "G0", distance 2.
