Solar Simulation Environmental Test Chamber
Solar Simulation Environmental Test Chamber supports solar-induced thermal load and functional operation of assemblies. Build the quotation around the specimen, programme and required measurements.

Test How Your Equipment Responds to Solar Radiation
Assess solar-induced heating and functional behavior under a defined radiation and chamber-temperature program. DERUI configures solar simulation systems around the required spectrum, exposed field, specimen heat load and measurement plan.
Discuss Your Solar Exposure Project

Define the Response Your Test Must Reveal
Solar heating and operation
For an outdoor enclosure, display, vehicle component or powered assembly, ask how absorbed radiation changes surface and internal temperatures—and whether the equipment still operates within its limits.
A useful test plan defines the power state, mounting, orientation and airflow, then records representative temperatures and functional responses. Candidate endpoints include overheating, control behavior, display performance or changes in seals and interfaces, according to the product specification.
Weathering is a different objective
For fading, cracking or mechanical-property loss, specify a material exposure and evaluation procedure. The spectrum, surface temperature and moisture sequence may differ from a solar-heating qualification.

Select the Correct Radiation-Testing System
| System | Primary purpose | Key selection requirement |
|---|---|---|
| Solar simulation chamber | Thermal and functional effects of radiation on equipment/components | Spectrum, irradiance field, thermal cycle, operating load and specimen measurements. |
| Xenon weathering chamber | Material change under filtered light and a defined climate/moisture cycle | Optical filters, irradiance channel, surface temperature, RH/wetting and evaluation endpoints. |
| Fluorescent UV tester | UV exposure with method-specific heat and moisture | Required UV lamp type and the prescribed condensation or spray cycle. |
| PV solar simulator / flasher | Electrical-performance measurement of cells or modules | Required simulator classification, spectral response, stability and electrical measurement system. |
These are not interchangeable procurement decisions. A xenon light source alone does not establish PV measurement capability, a thermal-vacuum environment or support for every weathering procedure.

Specify the Radiation Field and Specimen Heat Load
Spectrum and quantity
State the required spectrum and whether irradiance is total, integrated over a band or specified at a wavelength. W/m² and W/(m²·nm) describe different quantities; lux is not a substitute.
Geometry and uniformity
Define exposed surfaces, orientation, field size, working distance and mapping plane. For shaped parts, agree how different faces are measured. Cabinet volume does not establish irradiated-area coverage.
Thermal load
Include surface finish/color, material, mounting and electrical heat dissipation. Define chamber-air conditions separately from permitted surface and internal temperatures.

Project Configuration Inputs
Use this selection checklist to define the system proposal. It lists project inputs—not fixed performance ratings for every chamber.
| Configuration item | Information to supply |
|---|---|
| Test objective | Solar heating, operation under radiation or a defined weathering exposure |
| Governing procedure | Adopted standard edition, procedure, customer specification and acceptance criteria |
| Spectrum | Required spectral distribution, wavelength bands and optical-filter condition |
| Irradiance | Total or band-specific quantity, unit, setpoint, tolerance and cycle |
| Exposed field | Specimen dimensions, orientation, working distance and permitted non-uniformity |
| Thermal environment | Chamber-air profile, specimen temperature limits and airflow conditions |
| Specimen load | Mass, surface finish/color, mounting, operating power and heat dissipation |
| Monitoring | Surface/internal sensor locations, functional channels and recording requirements |
| Additional exposure functions | Humidity or wetting only where required by the selected procedure and included in the proposal |
| Installation | Destination electrical supply, cooling, ventilation, access and drainage where applicable |
IEC solar-radiation test selection
IEC 60068-2-5:2018 addresses equipment and components under simulated ground-level solar radiation. It includes thermal-effect and weathering approaches. Identify the required approach, cycle and acceptance criteria in the test plan.
For a customer or military qualification, supply the exact revision and procedure rather than a general standards name. The proposed optical field, climate program and measurement system must be reviewed together.

From Field Mapping to Acceptance Evidence
Before exposure
Identify specimens and baseline functional results. Fix the mounting, operating state, sensor locations, cable routing and exposure orientation.
During exposure
Record irradiance, chamber-air and specimen temperatures, operating state and selected functional channels. Define interruptions and thermal/functional abort limits in the procedure.
After exposure
Use the specified conditioning and functional checks. Evaluate performance against the approved limits, not a generic claim that the sample has “passed sunlight testing.”
| Acceptance item | Evidence to agree |
|---|---|
| Optical verification | Spectrum and quantity definition, radiometer calibration, setpoint response and field mapping at the declared working plane. |
| Loaded thermal response | Air and specimen sensor locations, heat-load conditions, operating profile and allowable limits. |
| Monitoring and records | Included sensor/functional channels, time-based records, deviations and required export/report format. |
| Utilities and safety | Final power/cooling requirements, room heat rejection, access, radiation protections and installed shutdown/alarm checks. |
Include lamp, optics, sensor calibration and field remapping in the maintenance plan. Relevant optical service or geometry changes can alter the exposure field and should trigger the verification required by the laboratory quality system.
For material-focused exposure, review the xenon weathering chamber. For UV/condensation programs, see the UV accelerated weathering tester. Compare optical exposure products in the xenon chamber range.

Compare the complete supply scope
Compare the complete optical configuration: lamp, filters, specimen exposure area, irradiance control, temperature measurement and selected moisture functions. Identify any spare lamp separately from operating lamps. Cooling water, purified spray water, room ventilation and electrical load must match the proposed build.

Choose the configuration for your application
Solar-induced thermal load and functional operation of assemblies.
Select daylight or window-glass filtering, specimen racks, irradiance control, moisture stages and recording according to the exposure programme. For solar-heating projects, define the illuminated area and uniformity, specimen heat balance and powered operation separately from accelerated weathering.
DERUI solar simulation system
Agree the factory acceptance record
Witness the installed optical filter and lamp identification, irradiance calibration at the defined wavelength or band, temperature channels and exposure sequence. Check specimen placement and the agreed uniformity map. A lamp power or illuminance reading is not a substitute for spectral irradiance, and a material-weathering configuration is not automatically a classified photovoltaic solar simulator.
