Large-Area LED Solar Simulator 3A+

The Large-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.
