Overview
The Atlas WAD-1202S Solar Simulation Aging Test System is a precision-engineered xenon-arc-based accelerated weathering instrument designed to replicate terrestrial solar irradiance and associated environmental stressors—including UV exposure, thermal cycling, and humidity—under controlled laboratory conditions. Built upon the globally recognized Atlas Ci series platform, the WAD-1202S employs long-arc xenon lamp technology compliant with CIE Publication No. 85 (1989) for spectral power distribution (SPD) fidelity, ensuring photometric and radiometric traceability to natural sunlight (AM1.5G). Its core function is quantitative photochemical degradation assessment of photovoltaic (PV) modules, encapsulants, backsheets, and related optoelectronic materials—enabling predictive lifetime modeling in accordance with IEC 61215, IEC 61646, UL 1703, and ASTM G155 protocols.
Key Features
- Xenon arc light source with water-cooled, long-arc lamp configuration delivering stable, spectrally accurate irradiance across 290–2500 nm
- Integrated environmental chamber enabling simultaneous control of black-panel temperature (BPT), chamber air temperature (CAT), and relative humidity (RH) within ±0.5 °C and ±3% RH accuracy
- Programmable irradiance control (0.35–1.10 W/m² @ 340 nm or 250–1200 W/m² total irradiance) with real-time feedback via calibrated broadband and narrowband sensors
- Automated spray cycle system with deionized water delivery, adjustable frequency/duration, and uniform nozzle distribution for wet/dry cycling per ISO 4892-2
- Robust stainless-steel chamber construction with quartz-filtered optical path, minimizing spectral distortion and thermal load on test specimens
- Compliance-ready architecture supporting audit trails, user access levels, and electronic signature functionality aligned with FDA 21 CFR Part 11 and GLP/GMP documentation requirements
Sample Compatibility & Compliance
The WAD-1202S accommodates PV module samples up to 120 cm × 80 cm—optimized for mid-sized crystalline silicon (c-Si), thin-film, and emerging organic photovoltaic (OPV) devices. Mounting fixtures support both horizontal and tilted configurations (0°–30°) to emulate field-angle-dependent irradiance incidence. All operational parameters adhere to international standards including ISO 4892-2 (xenon-arc exposure), IEC 61215-2 (qualification testing of terrestrial PV modules), and ASTM D4459 (accelerated exposure of plastics using fluorescent UV lamps—supplemented by xenon validation). Calibration certificates are traceable to NIST or equivalent national metrology institutes.
Software & Data Management
Control and data acquisition are managed via Atlas’ proprietary SunTest™ software suite (v5.2+), running on embedded Windows IoT OS. The interface supports multi-step test profiles with conditional logic (e.g., “if irradiance drops below threshold, pause and recalibrate”), real-time graphing of irradiance, temperature, RH, and spray status, and export of raw time-series datasets in CSV/Excel format. Audit logs record operator ID, timestamp, parameter changes, calibration events, and system faults—retained for ≥36 months. Optional integration with LIMS platforms via OPC UA or RESTful API enables automated data ingestion into enterprise quality management systems.
Applications
- Accelerated aging of PV module encapsulants (EVA, POE, TPO) to assess yellowing, delamination, and acetic acid evolution
- UV stability evaluation of anti-reflective coatings and front-glass surface treatments
- Correlation studies between lab-based xenon exposure and real-world field performance (e.g., desert, tropical, alpine deployments)
- Qualification testing per IEC TS 63209 (photovoltaic module reliability prediction) and UL 61730 safety certification
- Material screening for next-generation perovskite and tandem solar cells requiring low-dose, high-fidelity spectral simulation
FAQ
What spectral standard does the WAD-1202S meet?
It complies with CIE 85:1989 for daylight simulation and meets Class A requirements of ISO 4892-2 for spectral irradiance distribution.
Can the system perform combined UV + humidity + thermal cycling tests?
Yes—fully synchronized control of irradiance, black-panel temperature (25–110 °C), chamber temperature (10–90 °C), and relative humidity (10–95% RH) is supported.
Is third-party calibration included with purchase?
A factory-issued NIST-traceable calibration report for irradiance and temperature sensors is provided; annual recalibration services are available under Atlas’ Certified Service Program.
Does the system support remote monitoring and diagnostics?
Yes—via Ethernet-connected SunTest™ software with optional secure cloud telemetry (TLS 1.2 encrypted) for real-time status alerts and firmware updates.
How is sample uniformity ensured across the test plane?
Irradiance uniformity is validated to ±15% over the defined test area per ISO 4892-2 Annex B, using a 10×10 grid of calibrated reference sensors during commissioning.
