IEC 61215 MQT10 UV Preconditioning Test Chamber

Name: IEC 61215 MQT10 UV Preconditioning Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

The IEC 61215 MQT10 UV Preconditioning Test Chamber is specifically engineered to evaluate the light-degradation resistance of photovoltaic (PV) modules and materials — including EVA/POE encapsulants and backsheets — prior to thermal cycling (MQT 11) and humidity-freeze testing (MQT 12). Fully compliant with IEC 61215-2:2021 MQT 10, IEC 61730, and IEC 61646, the chamber delivers precisely controlled UV dosage (UVA + UVB) with uniform temperature regulation to ensure certification-level test accuracy — from single lab samples up to full-size, multi-module production panels.

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

Applicable Standard：IEC 61215-2:2021 MQT 10, IEC 61730, IEC 6164

Key Features of IEC 61215 MQT10 UV Preconditioning Test Chamber

Strict Standard Compliance — Fully complies with IEC 61215-2 (MQT 10), IEC 61730, and IEC 61646 UV preconditioning test requirements.
Precise Spectrum Control — Delivers a stable UVA/UVB/UVC ratio (UVC < 0.1%, UVB 3%–10%, UVA 90%–97%) to reach the target cumulative dose of 15 kWh/m² (320–400 nm) and 7.5 kWh/m² (280–320 nm).
Advanced Temperature Regulation — Maintains ambient-to-90°C ±2°C chamber temperature and 35–80°C Black Panel Temperature (BPT), with continuous automatic sensor feedback.
Large Capacity & Custom Dimensions — Standard specimen holder accommodates 1400 × 2400 mm (W×H), holding 2/4/6+ modules per cycle; custom-engineered racks available for irregular or oversized panels.
Online UV Intensity Monitoring — Integrated radiometer system continuously measures UV intensity and auto-calculates cumulative exposure dosage, with maximum UV irradiance capped at < 250 W/m².
Full-Coverage UV Exposure Design — Lamp layout and specimen positioning are engineered to eliminate shadowing and edge under-exposure, ensuring every module receives uniform irradiance across its entire surface.

Why UV Preconditioning Is Critical for PV Modules

According to IEC 61215 MQT 10, PV modules must undergo a minimum total UV exposure of 15 kWh/m² before entering thermal cycling (MQT 11) or humidity-freeze testing (MQT 12). This process identifies susceptible polymer materials — such as backsheet yellowing, delamination, or EVA discoloration — that could otherwise lead to field failures in solar power plants after years of outdoor exposure.

IEC 61215 MQT10 UV Preconditioning Test Chamber Details

UV Lamp Array

20 fluorescent UVA lamps + 10 UVB lamps generate a stable, uniform spectrum (UVA 90–97%, UVB 3–10%, UVC < 0.1%) with maximum UV irradiance controlled below 250 W/m², precisely matching IEC 61215 MQT10 dosage requirements for repeatable degradation testing.

Programmable Touchscreen Controller

A color LCD touch interface enables multi-segment programming of UV dosage, chamber temperature, and Black Panel Temperature (35–80°C), with real-time monitoring, data logging, and automatic dosage calculation for unattended long-duration test cycles.

SUS304 Stainless Steel Interior

The interior chamber lining uses corrosion-resistant SUS304 stainless steel, paired with a coated steel-plate exterior, to withstand continuous high-intensity UV and heat exposure — reducing long-term maintenance and extending equipment service life.

Insulation & Safety Protection System

Polyurethane foam and insulation cotton maintain stable chamber temperature up to 90°C ±2°C, while built-in over-temperature protection and a UV radiation door lock safeguard operators and specimens throughout the test cycle.

Custom-Engineered for Your PV Module Shape & Size

Solar panels come in a wide range of formats — standard rectangular modules, large-format utility-scale panels, BIPV (building-integrated) modules, flexible/curved panels, and irregular custom shapes. A one-size-fits-all chamber often leads to uneven UV exposure, shadowed edges, and unreliable dosage readings — all of which can compromise IEC 61215 test validity.

To solve this, the UVP-02 series can be custom-configured around your specific PV module specifications, including:

Custom Internal Chamber Dimensions — Tailored width, depth, and height to fit your largest module footprint, from small lab coupons to full utility-scale panels.
Adjustable & Modular Specimen Racks — Multi-tier or tilt-angle mounting fixtures designed to hold modules of varying shapes (rectangular, trapezoidal, curved, or irregular) securely and evenly.
Optimized Lamp Array Layout — UVA/UVB lamp spacing and positioning are recalculated for each specimen configuration to guarantee uniform irradiance across the entire module surface, including edges and corners, avoiding the shadowing or hotspot issues common with fixed-layout chambers.
Multi-Point Radiometer Placement — Additional UV sensor points can be positioned around larger or irregular layouts to verify that every zone of the panel receives the full target dose.
Multi-Module / Batch Testing Configurations — Racks can be engineered to test multiple panels simultaneously (2/4/6+ pieces) while maintaining consistent dosage and temperature across all specimens.

Our engineering team works directly from your PV module drawings or dimensions to design a chamber layout that guarantees complete, uniform UV contact across the full panel surface — helping you avoid retesting caused by uneven exposure and ensuring results that hold up to certification body scrutiny.
