A class for the optimization of shadows in a PV system.
Objects can be created by optimShd
.
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.
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.
signature(x = "Shade")
: conversion to a
data.frame including columns for distances (Lew
,
Lns
, and D
) and results (FS
, GRR
and Yf
).
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.
signature(x = "formula", data = "Shade")
:
display the content of the Shade
object with the
xyplot
method for formulas.
