The lowest uncertainties thanks to it’s A+++A++A+++ rating, going beyond IEC60409 requirements:
The Nexun Labs features the best spectrum on the market for a full led system with the lowest spectral deviation, thanks to 37 LEDs types and 32 channels per 15x15cm board area.
Available with an active illumination area up to 1800 x 3000mm, get covered for the biggest panels to come. On a budget? No worries, we can provide bigger frame and increase the area later!
At 500ms, with an LTI down to 0.1%, combined why the dynamic IV, measure the most capacitive technologies like the latest HJT.
The Nexun Labs has pulse length of up to 500ms, allowing you to measure even the latest, most capacitive HJT panels in a single flash!
The Nexun Labs is available as a vertical design, making manual loading and unloading of solar panels convenient for laboratories. The easy, single handed adjustable rack allows to adjust to different panel size in seconds while providing support for sensor like thermal probes. The system can be enclosed with a curtain or thermal chamber.
The automatic uniformity robot allows fast and fully automated measurement of the whole area. The cell size can be adjusted upon needs and the mapping steps and area are fully configurable.
At less than 2 seconds per position, even a 200 points mapping takes less than 10min.
The software integrate a self correction algorithm so that the uniformity can self-adjust in sequence, allowing to reach a uniformity record down to 0.5%.
Want to bring uncertainties even further ? You can configure the robot to match your panel cell position, and measure the uniformity at the same cell position as your panel for maximum accuracy.
The Nexun Labs is shipped with TUV Certificate.
The Nexun Labs is able to self assess with its diagnostic tool and check each LED for deflective LED, driver unit or communication issue, ensuring the best measurement at all time.
Beyond the integrated diagnostic, the LED can also light in steady-state at low intensity and by single wavelength which allows visual check.
With its 500ms pulse and the Dynamic IV, no HJT will ever need more than a single flash to be accurately measured.
The Bi-directional Dynamic IV technology and 500ms pulse mean 100 points with each 5ms stabilization, allowing an accurate measure of the most capacitive technologies without complex fitting algorithm or curve shaping.
The 4-quadrant active load allows for the most precise measurement with an accuracy of 0.05% FS.

Add a A+A+A+ steady-state light source to allows measurement of technologies requiring preconditioning like Perovskite.
Perform all the temperature test required by the Standard including TC Matrix, Thermal Coefficients, Kappa extraction, and multiple irradiance, all automatically.
Save time and work for your team!
Latest HJT Technologies requires up to 500ms flash time, which is especially critical for temperature coefficient measurement.
With 37 wavelengths, 35 of which are narrow wavelength, enables full control of the spectrum.
Adjust each wavelength precisely, create your own spectrum, simulate regions like desert, city, or sunrise & sunset.
Set your spectrum, and change in a single click!
The Nexun is powered by the industry’s most advanced software, with functionalities that speed up the lab process, improve traceability and work efficiency while limiting potential user errors.

The load is optimized for the measurement of high-hysteresis technologies like HJT, ensuring the fastest capacitive discharge of the panel during the measurement.
At the difference of most loads on the market, where V- and I- are short-circuited, Avalon’s load has a true, 4-point Kelvin connection with fully isolated I and V channels.
The load uses fully independent channels for each of the measured Voltage, Current, and Irradiance. Powered by high speed, 16bit converter with a low-noise optimized front end, a single IV is measured of 4’000 points.
Measure panels up to 30A and 250V with measurement ranges of 30A, 10A, 4A, 1A, 0.2A and 250V, 180V, 120V, 60V, 15V, 1V
A WPVS Reference cell can be directly connected to the load, thanks to its trans-impedance amplifier, removing the needs of an external shunt resistor, further reducing uncertainties.
You can connect up to 4 Infrared temperature sensors, ensuring precise monitoring of the temperature.
The optional PT100 box allows you to connect up to an 8 PT100 temperature probe for a precise measurement of the temperature coefficients.
The load is guaranteed to an accuracy of 0.05% to the selected measurement range, ensuring the lowest measurement uncertainties.
* Uniformity is guaranteed at 1%, 0.5% is dependent on good lab condition, good operation of the equipment and knowledge of the user. A stable room temperature and a clean optics is required as well as no external stray light. The uniformity robot is required and the uniformity shall be measured frequently. Uniformity is rated with a 6 inch cell and 4cm gap to the edge of the illumination area.
Bring your lab or production to a new level with a flexible, modular and up-gradable system.
