D_Losses-methods {solaR}

Losses of a GCPV system

Description

The function losses calculates the yearly losses from a Gef or a ProdGCPV object. The function compareLosses compares the losses from several ProdGCPV objects and plots the result with dotplot.

Usage

compareLosses(...)
losses(object)

Arguments

...

A list of ProdGCPV objects to be compared.

object

An object of Gef or ProdGCPV class..

Methods

signature(... = "Gef")

shadows and angle of incidence (AoI) losses.

signature(... = "ProdGCPV")

shadows, AoI, generator (mainly temperature), DC and AC system (as detailed in effSys of fProd) and inverter losses.
