Accurate and reliable measurement is essential for evaluating the performance of a solar simulator.
In photovoltaic research and optical testing, measurement methods must be transparent, reproducible, and clearly documented so that experimental results can be properly interpreted and compared.
This section explains the measurement methods used by SAN-EI when evaluating solar simulator performance. The purpose is not only to present results, but also to clarify how those results are obtained.
Three types of measurement are introduced.
Irradiance Measurement
describes the basic method used to measure irradiance on the illumination plane. It explains how irradiance values are obtained and how measurement conditions are defined during testing.
Pyranometer vs Reference Cell
explains the characteristics and differences between pyranometers and photovoltaic reference cells. Each sensor type has its own advantages and limitations, and understanding these differences is important when interpreting irradiance data.
Spectroradiometer Measurement
describes the method used to measure the spectral distribution of the solar simulator. Spectral measurements are essential for evaluating spectral match and verifying how closely the simulator reproduces the solar spectrum.
By presenting these measurement methods, SAN-EI aims to provide clear technical transparency so that researchers and engineers can correctly understand the basis of the reported performance data.
The following pages describe each measurement method in detail.
