Solar simulator performance is a critical factor for obtaining reliable and reproducible experimental results in photovoltaic research and optical testing.
A solar simulator must reproduce sunlight with sufficient spectral accuracy, spatial uniformity, and temporal stability so that device performance can be evaluated under well-defined illumination conditions.
However, performance specifications are often presented only as catalog values. In many cases, users cannot easily understand how a simulator actually behaves during operation.
At SAN-EI, we believe that solar simulator performance should be measured, verified, and openly presented so that researchers and engineers can clearly understand the characteristics of the illumination used in their experiments.
In this section, we present measurement results and technical explanations related to the performance of SAN-EI solar simulators.
