Interpreting Cylinder Plots



SERI_QC Flags: K-space Cylinders:
Irradiance ElementSymbolK-Space Conversion
Global HorizontalKtGlobal / Isc * ECF * Cos(Z)
Direct NormalKnDirect / Isc * ECF
Diffuse HorizontalKdDiffuse / Isc * ECF * Cos(Z)

    Isc = Solar Constant (1367 Wm-2)
    ECF = Eccentricity Correction Factor = (ro / r)2
      where,
        ro = mean Earth-Sun distance
        r = current Earth-Sun distance
    Z = Solar Zenith angle at time of measurement.
