{wiki=Solar_simulator}
A solar simulator is a device that replicates the solar spectrum and irradiance of sunlight in a controlled environment. These simulators are used primarily in research and testing applications, particularly for solar energy technologies, including photovoltaic cells, solar thermal systems, and related materials. **Key Features of Solar Simulators:** 1. **Spectral Matching:** Solar simulators produce light that closely resembles the spectral distribution of natural sunlight, typically defined by the ASTM E 927 or IEC 60904-9 standards.
