UV Preconditioning Test Chamber for Solar Panels

Name: UV Preconditioning Test Chamber for Solar Panels
Brand: Xi'an LIB Environmental Simulation Industry

The UV Preconditioning Test Chamber for Solar Panels is purpose-built to support ultraviolet exposure steps defined in IEC 61215 and IEC 61730 photovoltaic qualification workflows. The system delivers stable UVA-dominant radiation (320–400 nm) with controlled UVB contribution and UVC content, while maintaining stable chamber temperatures up to 90 °C and Black Panel Temperature (BPT) from 35 °C to 80 °C.

UV stress is managed through accumulated radiant energy control (kWh/m²), ensuring repeatable and standard-aligned preconditioning prior to damp heat, thermal cycling, and mechanical load tests. With configurable specimen capacity, pull-out module racks, and an industrial-grade stainless-steel SUS304 workroom, the Preconditioning Test Chamber enables reliable UV preconditioning for full-size photovoltaic modules in both certification and manufacturing environments.

Standard Models: UVP-02,UVP-04,...and more customized model based on your needs.

Key Performance Advantages of UV Preconditioning Test Chamber for Solar Panels

1. Solar-Relevant UV Spectrum Composition

The irradiation system delivers a UV spectrum dominated by UVA (≈90–97%), with controlled UVB contribution (≈3–10%) and negligible UVC content (<0.1%), closely matching natural solar exposure conditions.

2. Energy-Based UV Dose Control

UV preconditioning is governed by cumulative energy targets, such as defined exposure levels in the 280–320 nm and 320–400 nm bands, ensuring consistent material stress across different test batches.

3. Independent Thermal & BPT Regulation

Chamber air temperature (ambient to 90 °C, ±2 °C) and Black Panel Temperature are regulated independently, preventing thermal coupling from distorting pure UV aging mechanisms.

4. Full-Size PV Module Compatibility

Vertical specimen holders support large solar panels with stable exposure geometry, enabling simultaneous testing of multiple modules without irradiance shadowing.

5. Designed for IEC-Oriented Test Sequences

Optimized as a UV preconditioning stage before damp heat, thermal cycling, or combined climatic tests required in photovoltaic qualification workflows.

Practical Questions - UV Preconditioning Test Chamber for Solar Panels

Q1: How is UV exposure controlled—by time or by energy?
The chamber controls UV preconditioning primarily by accumulated radiant energy (kWh/m²), which provides higher repeatability and aligns better with IEC photovoltaic test logic.

Q2: Can LIB industry customize the system for different PV module formats?
Absolutely. LIB industry customizes specimen rack dimensions, module quantity, UV configuration, and control logic to match your exact IEC test workflow.

Q3: What support does LIB industry provide beyond the chamber itself?
LIB industry delivers complete PV testing support, including chamber customization, test sequence consultation, installation guidance, operator training, and long-term technical service.
