Hoenle IR Solar Simulator System

Overview

The Hoenle IR Solar Simulator System is a high-intensity, industrial-grade infrared irradiation platform engineered for accelerated thermal stress testing, solar thermal component validation, and photovoltaic module pre-conditioning under controlled IR spectral conditions. Unlike broadband xenon-based solar simulators optimized for AM1.5G spectral matching, this system leverages focused near- and mid-infrared radiation (IR-A: 800–1400 nm; IR-B: 1400–3000 nm) to deliver rapid, volumetric heating with minimal thermal inertia. Its core principle relies on resistive thermal emission from double-ended tungsten-halogen linear lamps—each operating at filament temperatures exceeding 2800 K—producing a continuous blackbody-like spectrum peaking in the IR-A band. This enables precise replication of solar-induced thermal loading profiles without significant UV or visible-light contribution, making it especially suitable for applications where photodegradation must be decoupled from thermal degradation.

Key Features

• Double-ended tungsten-halogen emitters (1000 W or 2000 W variants), rated for ≥5000 hours operational lifetime under nominal load
• Integrated white reflective parabolic reflectors ensuring directional collimation and uniform irradiance distribution across target plane
• Electronically controlled dimming module enabling continuous 0–100% power regulation with <±0.5% setpoint stability
• Energy conversion efficiency >90% — electrical input to infrared radiant output — minimizing cooling demand and operational cost
• Modular mechanical architecture supporting vertical lift (height adjustment), ±15° pitch/yaw tilt, and programmable X/Y translation of emitter arrays
• PLC-integrated control interface compliant with IEC 61131-3 standards; optional handheld HMI for local operation and real-time irradiance monitoring

Sample Compatibility & Compliance

The system accommodates flat-panel samples up to 4.5 m × 5.5 m per side (multi-sided configuration), with custom layouts scalable to 3.8 m × 11 m total irradiated area. It supports rigid and semi-flexible substrates including silicon PV modules, CPV receivers, thermal barrier coatings, automotive glazing, and polymer-based encapsulants. All configurations are designed in accordance with DIN EN 61215-2 (photovoltaic module qualification), ISO 9001:2015 manufacturing traceability requirements, and IEC 61730 safety standards for electrical insulation integrity under thermal cycling. Radiation uniformity is verified per IEC 60904-9 Annex A using calibrated thermopile array sensors; typical spatial non-uniformity remains ≤±5% over defined test planes.

Software & Data Management

Control firmware supports deterministic real-time sequencing via integrated PLC logic, with configurable ramp rates (0.1–10 K/min), dwell times (1 s–99 h), and multi-step thermal profiles. Data logging records irradiance (W/m²), lamp voltage/current, ambient temperature, and positional feedback at 10 Hz sampling rate. Export formats include CSV and HDF5 for post-processing in MATLAB or Python-based analytics pipelines. Audit trails comply with GLP and GMP principles: all parameter changes, operator logins, and system events are timestamped and digitally signed. Optional integration with SCADA platforms (e.g., Siemens WinCC, Rockwell FactoryTalk) enables centralized fleet monitoring and remote diagnostics.

Applications

• Thermal shock and cyclic aging tests for PV modules per IEC 61215-2 MQT 10 (Thermal Cycling) and MQT 11 (Humidity Freeze)
• Accelerated lifetime assessment of encapsulant materials (EVA, POE) under IR-dominated heating to evaluate delamination kinetics
• Validation of IR-selective absorber coatings used in concentrated solar power (CSP) receivers
• Automotive component testing: windshield de-icing simulation, dashboard material warpage analysis, and headlamp thermal lensing evaluation
• R&D of thermally responsive smart windows and electrochromic devices requiring rapid, non-contact heating protocols

FAQ

What spectral range does the Hoenle IR Solar Simulator cover?
The system emits primarily in the IR-A (800–1400 nm) and IR-B (1400–3000 nm) bands, with negligible output below 800 nm or above 10,000 nm.
Can irradiance uniformity be validated per international standards?
Yes — uniformity mapping follows IEC 60904-9 Annex A methodology using NIST-traceable thermopile sensors; reports include full uncertainty budgets per ISO/IEC 17025.
Is the system compatible with environmental chambers?
All mechanical interfaces and cabling are rated for integration into Class II climatic chambers (−40 °C to +120 °C); optional water-cooled lamp housings available for sustained high-power operation.
How is calibration maintained over time?
Lamp aging is tracked via real-time current/voltage monitoring; factory recalibration service includes spectral radiance verification using FTIR spectroradiometry and irradiance recalibration against primary standard reference detectors.
Does the control system support 21 CFR Part 11 compliance?
Yes — optional 21 CFR Part 11 add-on package provides electronic signatures, role-based access control, and immutable audit logs for regulated pharmaceutical and medical device thermal validation workflows.
