Nexun One Module
The New Standard of PV Metrology
IEC60904-9 Ed. 2: A+A+A+
IEC60904-9 Ed. 3: A+A+A+
The Nexun One
Avalon’s flagship solar simulator. From production to advanced lab and research, it’s 200ms pulse and adjustable spectrum offers the tools needed to properly measure PERC and HJT technologies.
Unrivaled Spectrum
The lowest spectral mismatch on the market
The Nexun One ensures that you meet the highest industry standards. Its spectrum reaches A++ for both IEC60904-9 Ed 2. and Ed3., with a Spectral Deviation lower than 17% compared to 35% for most Xenon and >100% for other LED systems.
Each of the 32 wavelengths are individually controlled, allowing you to tune the spectrum as needed.
Proven stability and repeatability over 100’000 measurements.
Meet the Standards of Today and Tomorrow!
LEDs
Divided in 15x15cm individually adjustable zone, more 10’000 LEDs powers the simulator with an adjustable intensity from 20 to 1’000W/m2.
The LEDs are sourced from leading manufacturers in the US and Japan, regulated by in-house, closed loop analog drivers guaranteeing the highest short and long term stability.

200 to 500 milliseconds
flash pulse. Measure high capacitive devices as PERC, Hetero-Junction with a longer pulse, removing the needs of special computational IV techniques that are prone to errors. The basic configuration is 200ms.
Bi-Facial
Measure bi-facial modules with our double illumination source. Both sources can be individually modulated and the flasher is up-gradable, allowing you to spread the cost by upgrading your simulator at a later time.
36 Million Flashes
Provides you with an LED lifetime of 10-15 years in production. All LED are driven below steady-state rating ensuring a longer life time and slower degradation than competing products. After that, we can replace the LEDs for you.
Thermal Chamber
Our fully automated thermal chamber comprises of 28 individually controlled zone to speed up the process. Combined with the configurable software, setup your measurement process so that it can be performed fully automatically.
15 Seconds Cycle Time
Allows to meet the most constrained production speed of today, and tomorrow.
Modular Design
The modular design allows customization of the active area for specific needs.
Light Modulation
The Nexun One has the ability to modulate its spectrum and spectral configuration or irradiation can be changed each millisecond of the flash, opening new perspectives.
Software
Nexun Software is the most flexible system out-there. Fully database synced, you keep trace of your measurements.
The software include a full data management system that perfectly fits laboratory data management as well as production. Keep track of your clients, measurements and automatically generate test reports based on your template.
Statistical analysis allows you to keep track of the production performances and system performance. The calibration process for production allows for fool-proof automated calibration without the need to even touch the software.
Want to customize? The full API access, or even better, create your own plugin and integrate it within the software, you can then even sell your work to other Nexun’s user.
Plugin for data extraction and processing are available and we can also develop custom plugins for your particular needs.
Maintenance
The system is designed for simple maintenance. Provided with spare parts out of the box, and using widely available power supplies, most of the potential issue can be fixed by yourself without the need of waiting an engineer to fly in.
With The Nexun One
Bring your lab or production to a new level with a flexible, modular and up-gradable system.
