Effect of I-V translations of irradiance-temperature on the energy yield prediction of PV module and spectral changes over irradiance and temperature

photovoltaic (PV) community as it, unless
power rating at standard conditions, allows an
accurate estimation of the performance of PV
modules in different climatic conditions. The
device characterisation currently requires the
measurement of a performance matrix using
irradiance and temperature where values
between measurements might be interpolated.
Spectral changes are included by correcting
using a quantum efficiency measurement. I-V
translations of PV modules give better idea
about the measurements of the PV modules as
a function of irradiance and temperature. Two
methods of I-V translations are applied in this
study. Bilinear interpolation between the
consecutive points of three selective data sets
of irradiance and temperature in the power
matrix reduces the prediction error below 2.5%
compared to over 6% with linear interpolation
between two extreme data set points in the
power matrix.
