TheLarge-Area LED Solar Simulator 3A+is designed to provide a controllable, repeatable, and standardized “solar environment” for testing large photovoltaic (PV) modules in laboratory settings. You use this simulator to replicate real solar irradiance across meter-scale areas, allowing comprehensive performance evaluation of PV modules under precise, uniform, and programmable light conditions. Its LED-based system ensures high spectral accuracy, exceptional uniformity, instant response, and long-term reliability, making it suitable for both R&D and production line testing of large-scale photovoltaic products.
Applications
Mass Grading of Large-Size PV Modules: Rapidly test and grade output power at production line end-of-line inspections.
PV Module Research and Development: Evaluate novel modules such as HJT, TOPCon, and perovskite under standardized solar conditions.
PV Module Certification: Facilitate IEC-compliant testing for quality assurance and certification purposes.
Bifacial Module Testing: Simultaneously or independently measure front and rear power generation efficiency.
Agri-PV and Building-Integrated Photovoltaics (BIPV) Testing: Deliver customized testing for specialized PV applications.
Standards
(1) IEC 60904-9 – Photovoltaic Devices: Performance Requirements for Solar Simulators
(2) ASTM E927 – Standard Guide for Laboratory Simulation of Solar Radiation
(3) IEC 60904-3 – Measurement of Photovoltaic Current-Voltage Characteristics
(4) ISO 9060 – Solar Irradiance Measurement and Calibration Standards
(5) IEC 61853 series – Photovoltaic Module Performance Testing under Standard Test Conditions
Features
Unparalleled Uniformity: You achieve extremely high irradiance uniformity across the entire module surface.
Superior Spectral Matching: Multi-channel LED combination ensures accurate reproduction of the solar spectrum, including critical UV and IR bands.
Instant Switching and Flicker-Free Output: Supports millisecond-scale flash testing without warm-up.
Ultra-Long Lifespan and Low Maintenance: LED light sources provide stable output over tens of thousands of hours, reducing operational costs.
Programmable Flexible Spectrum: Independently control wavelength bands to simulate different times, atmospheric conditions, and solar spectra.
