B7_Shade-class: Class "Shade": shadows in a PV system.

Description

A class for the optimization of shadows in a PV system.

Arguments

Objects from the Class

Objects can be created by optimShd.

Slots

FS:: numeric, shadows factor values for each combination of distances.
GRR:: numeric, Ground Requirement Ratio for each combination.
Yf:: numeric, final productivity for each combination.
FS.loess:: A local fitting of FS with loess.
Yf.loess:: A local fitting of Yf with loess.
modeShd:: character, mode of shadows.
struct:: A list with the dimensions of the structure.
distances:: A data.frame with the distances between structures.
res: numeric, difference (meters) between the different steps of the calculation.

Besides, as a reference, this class includes a ProdGCPV object with the performance of a PV systems without shadows.

Extends

Class "ProdGCPV", directly. Class "Gef", by class "ProdGCPV", distance 2. Class "G0", by class "ProdGCPV", distance 3. Class "Meteo", by class "ProdGCPV", distance 4. Class "Sol", by class "ProdGCPV", distance 4.

Methods

as.data.frame: signature(x = "Shade"): conversion to a data.frame including columns for distances (Lew, Lns, and D) and results (FS, GRR and Yf).
shadeplot: signature(x = "Shade"): display the results of the iteration with a level plot for the two-axis tracking, or with conventional plot for horizontal tracking and fixed systems.
xyplot: signature(x = "formula", data = "Shade"): display the content of the Shade object with the xyplot method for formulas.
