C_fProd: Performance of a PV system

Description

Simulate the behaviour of a grid connected PV system under different conditions of irradiance and temperature. This function is used by the prodGCPV function.

Usage

fProd(inclin, module, generator, inverter, effSys)

Arguments

inclin

A Gef object, a zoo object or a data.frame. In case of being zoo or data.frame it must include a component named Gef (effective irradiance, W/m²)

module

list of numeric values with information about the PV module, [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

generator

list of numeric values with information about the generator, [object Object],[object Object]

inverter

list of numeric values with information about the DC/AC inverter, [object Object],[object Object],[object Object],[object Object]

effSys

list of numeric values with information about the system losses, [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Value

• If inclin is zoo or Gef object, the result is a zoo object with these components (if inclin is a data.frame the result is also a data.frame with these same components):
• Tc
  cell temperature, $^{\circ}{\rm C}$.
• Voc, Isc, Vmpp, Impp
  open circuit voltage, short circuit current, MPP voltage and current, respectively, in the conditions of irradiance and temperature provided by Inclin
• Vdc, Idc
  voltage and current at the input of the inverter. If no voltage limitation occurs (according to the values of inverter$Vmax and inverter$Vmin), their values are identical to Vmpp and Impp. If the limit values are reached a warning is produced
• Pdc
  power at the input of the inverter, W
• Pac
  power at the output of the inverter, W
• EffI
  efficiency of the inverter
