Photovoltaic standards mandate that Class AAA solar simulators meet demanding requirements in three key performance areas: spectral match to the solar spectrum, spatial non-uniformity of irradiance, and temporal instability of irradiance.
There are three standards that define solar simulator performance.
• IEC 60904-9 Edition 2 (2007) Photovoltaic Devices – Part 9: Solar Simulator Performance Requirements
• JIS C 8912-1998, Solar Simulators for Crystalline Solar Cells and Modules
• ASTM E 927-05 (2005) Specification for Solar Simulation for Terrestrial PV Testing
