PV modules need to be tested under controlled light conditions so laboratories can understand how they perform before installation, during quality checks or after time in the field. Reliable measurement depends on reproducing sunlight consistently and capturing useful electrical performance data from the module.

Avalon Solar develops solar simulator and PV metrology technologies for these testing needs. Its Nexun systems support controlled laboratory measurement, while the Mobile Lab brings selected PV testing capabilities directly to plants and project locations. At the scientific equipment exhibition Dubai, Business Communications LLC will present these technologies for visitors working across photovoltaic research, quality control and field testing.

Recreate Sunlight to Measure PV Module Performance

A solar simulator allows laboratories to test PV modules under a controlled light source instead of depending on changing outdoor sunlight.

This makes it easier to repeat measurements, study module behaviour and maintain consistent test conditions.

Nexun PRO Max: Controlled Testing Inside the Laboratory

The Nexun PRO Max is an LED solar simulator designed for quality and advanced laboratory environments.

Avalon Solar specifies the system with 22 wavelengths across 300–1200 nm, peak irradiance of 1300 W/m² and an active area of up to 1.8 × 3 m. It is rated A++ A+ A++ under IEC 60904-9.

For a laboratory, this type of PV solar simulator can support work involving:

• PV module performance measurement
• Controlled IV testing
• Silicon module testing
• Perovskite and thin-film applications with suitable configuration
• Quality-control measurements
• Research and development

The main advantage is consistency. Instead of waiting for ideal outdoor conditions, the laboratory can reproduce defined light conditions whenever measurements are required.

Why LED Solar Simulation Matters

A solar simulator needs to do more than simply produce bright light.

For useful PV measurements, the light needs to match important characteristics of natural sunlight, remain stable during the test and illuminate the module evenly.

Avalon's Nexun platform is built around LED-based simulation for IEC 60904-9 measurement. The wider product family is designed around controlled spectrum, pulse duration and active-area requirements for different PV technologies.

For teams looking at PV module testing equipment, these factors can influence how repeatable and useful the final measurement becomes.

From the Lab Bench to Full-Size Modules

PV testing needs can vary according to the size and technology of the device being measured.

A research team working with smaller samples may have very different requirements from a quality laboratory measuring complete modules.

The Nexun PRO Max is designed for full-size module measurement, allowing laboratories to work with large active areas while maintaining controlled illumination.

This makes the system relevant when full-module testing is part of the laboratory workflow.

Take PV Testing Beyond the Fixed Laboratory

Not every PV measurement needs to happen inside a permanent facility.

Modules may already be installed at a solar plant, stored at a project site or located far from the laboratory. In these situations, transporting modules back for testing can add time and handling.

A mobile setup changes that process by bringing the measurement capability closer to the modules.

Mobile Lab: Bring the Test Setup to the Site

Avalon's Nexun Mobile Lab is designed for field-deployable PV testing.

The system combines IV flash testing, electroluminescence imaging and hipot testing within a mobile configuration that can be supplied in formats such as a van, trailer or container. Avalon states that the setup can process more than 60 modules per hour depending on configuration and workflow.

A mobile PV testing lab can be useful for:

• Solar plant inspections
• Field PV testing
• On-site module assessment
• Quality checks after installation
• Large project sites
• Situations where module transport is impractical

This allows testing to move closer to where the PV modules are actually installed or stored.

When Does Mobile Testing Make More Sense?

A fixed laboratory provides a controlled environment, but field testing can be valuable when the modules themselves are difficult to move.

Before choosing between laboratory and mobile testing, teams can consider:

• Are the modules already installed?
• How many modules need to be checked?
• Is transportation practical?
• Is on-site IV measurement required?
• Are visual or electrical defects being investigated?
• Does the project involve several remote locations?

For some applications, a laboratory-based photovoltaic solar simulator is the right approach.

For others, a mobile solar testing laboratory can reduce the distance between the testing equipment and the PV installation.

See PV Metrology from Laboratory to Field at ARABLAB 2026

At Sheikh Saeed Hall 1, Stand SSH1-B40, visitors can learn how Solar technologies address PV measurement in two very different environments.

The BCL showcase at ArabLab Live 2026 will give visitors an opportunity to understand:

• Controlled LED solar simulation
• Full-size PV module testing
• IV performance measurement
• Laboratory-based PV metrology
• Mobile and on-site PV testing
• How testing needs change between the laboratory and the field

For professionals attending the scientific equipment exhibition Dubai, this provides a practical look at how PV measurement can move from a controlled laboratory setup to testing directly at the project location.
