fCompI: Calculation of solar irradiance on a horizontal surface

Description

From the daily global, diffuse and direct irradiation values supplied by fCompD, the profile of the global, diffuse and direct irradiance is calculated with the rg and rg components of fSolI.

Usage

fCompI(CompD, SolI)

Arguments

CompD

data.frame as provided by fCompD

SolI

data.frame as provided by fSolI

Value

• A data.frame including the result of merge(CompD,SolI,sort=FALSE) and three additional components:
• G0
  numeric, global irradiance on a horizontal surface, (W/m²)
• D0
  numeric, diffuse irradiance on a horizontal surface, (W/m²)
• B0
  numeric, direct irradiance on a horizontal surface, (W/m²)
