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.
