AAA-Class Solar Simulator
AAA-Class Solar Simulator is a high-performance device designed to replicate sunlight for testing and research purposes. It can simulate key parameters of solar irradiation, including intensity, spectrum, color, uniformity, and temporal stability. The simulator is essential for evaluating solar cells, solar water heaters, and other photovoltaic products. The “AAA” designation represents the highest international standard ratings for spectral match, irradiance uniformity, and temporal stability, ensuring highly accurate and reproducible results in material science, photovoltaics, and environmental testing applications.
Application
The AAA-Class Solar Simulator is widely applied across various research and testing scenarios, including:
Photovoltaic Testing:
Efficiency measurements of solar cells (I-V curves, quantum efficiency)
Module aging and reliability tests (PID, LID effects)
Materials Research:
Evaluation of photocatalytic materials
Performance testing of photothermal conversion materials
Environmental Simulation:
Accelerated weathering tests for spacecraft components
UV aging tests for automotive coatings
The simulator supports a wide range of solar energy products, material studies, and environmental simulation experiments.
Standards
The simulator conforms to key international standards, including:
(1) IEC 60904-9:2020 – Photovoltaic devices – Part 9: Solar simulator performance requirements
(2) ASTM E927 – Classification of solar simulators for photovoltaic device testing
(3) JIS C8912 – Solar simulators for crystalline silicon photovoltaic cells and modules
