Solar Simulation Systems

Degradation and Heat

Sunlight can have adverse affects on materials and components, oftentimes initiating and accelerating the degradation process as it interacts with temperature, moisture and other environmental effects. In addition, it is critical to understand the effects of heat created by sunlight with respect to operational performance, thermal management, noise and dimensional stability. A new product should be tested under solar environmental conditions representative of those locations in which it will exist - anywhere ranging from the heat of the outback in Australia to the frigid climate of arctic areas. Atlas solar simulation systems are custom-designed in both power and size. Having this flexibility, they can be integrated into various types of environmental test chambers whether they be small or walk-in, chambers used in component/ small product testing or drive-in chambers for complete vehicle testing, even up to extra large systems for trains, trucks and aircrafts.

Superior Solar Simulation with SolarConstant

A key to the success of solar environmental testing is the quality of the solar simulation itself. A close spectral match to natural sunlight is critical for accurate reproduction of test conditions. The Atlas SolarConstant luminaire offers high irradiance efficiency and superior spatial uniformity on the test area. Combined with special Metal Halide Global (MHG) lamps and optical filters, the SolarConstant creates a spectral distribution that closely matches natural sunlight. Its proven modular design makes this unit ideal for large custom-designed solar simulators as well as smaller standardized laboratory test systems.











SolarConstant Serving Global Testing Needs

SolarConstant products are designed to meet a large number of standards as well as industry test methods such as DIN 75220, MIL-STD-810, IEC 61215, IEC 904-9, EPA 40-CFR/ SC03, BMW PR306.5, Renault 32-00-022, Telcordia GR-487-CORE and others.

Atlas offers a complete series of SolarConstant luminaires to satisfy an array of global testing needs:


  • SolarConstant MHG 4000/2500/1200/575:
    These luminaires utilize Metal Halide Global technology for full-spectrum solar simulation. Optical filters adjust the output for the best match to natural indoor/outdoor sunlight. They are ideal for solar simulators used to determine thermal heating effects of solar radiation such as fit and finish, dimensional stability or thermal transmission. They are also suited for identifying photodegradation effects of polymers and coatings such as cracking, color fading and other failures, or testing PV module performance.

  • SolarConstant MIL:
    These luminaires utilize Metal Halide Global technology combined with a unique "multi-level" output for full-spectrum solar simulation. Especially useful for satisfying stringent MIL-STD-810G method 505.5 (Procedure I) - determination of heat produced by 24-hour cycles of solar radiation. It is also ideal for agro-science requiring diurnal cycles, e.g. plant growth studies and others.

  • SolarConstant MH 1500/1200/1000:
    These luminaires utilize Metal Halide technology for specific high-UV level testing or to meet limited budget applications.

  • Solar Constant UV 2000:
    These luminaires utilize Mercury technology for creating UV radiation (280 - 400 nm) and are used to study photo-aging effects caused by solar UV radiation only.

In addition to the SolarConstant line of products, Atlas comolements its luminaire portfolio with Halogen technology for visible (VIS) and heat radiation (IR). IR-luminaires with 2000W / 1500 W are used to set up high-performance systems for testing heating effects similar to heating caused by sunligt.

From Outdoor Data to Laboratory Testing

No environmental laboratory test is complete withut the confirmation and correlation to natural conditions. Atlas operates a number of outdoor exposure sites in key climate zones worldwide and can produce the natural exposure data you need. Using our expertise in both outdoor and accelerated testing, Atlas can assist you in reproducing outdoor conditions in your laboratory enabling your testing to reliable, fast and as realistic as possible.

Test Chamber Examples

Atlas has installed over 100 systems worldwide and is a leader in combining the technologies of testing with solar simulation. Below are examples of the most common test chambers with solar simulators:

Climate test chamber with wind tunnel and solar simulator  

Climate test chamber with dynamometer and solar simulator

Solar heat load test chamber with solar day cycling

Climate test chamber with dynamic road simulation and solar simulator

Custom solar simulator for PV module testing, Light Soak testing, I/V curve tracing

Solar environmental Walk-in test chamber for component / product testing


Atlas' CESORA (Calculation of Effective Solar radiation) software is extremely useful in the absence of measured outdoor data. With CESORA, you can calculate effective solar radiation for any time, day, month or year on any titled surface over any spectral range from 250-3000 nm.

Positioning System

To allow the SolarConstant solar simulator to move and replicate various natural solar conditions, a mechanical positioning system is typically installed. This enables motorized movement of the solar array within all desired spatial directions to simulate solar day cycles for example. Atlas offers both low-cost manual remote controls or full automatic alternatives that are integrated into the Atlas software.

Positioning systems are typically customized towards the application and local test facility. Atlas will work with you to define the SolarConstant positioning system that will work best for you.

Control System

The operation of the SolarConstant system is handled by a dedicated operator interface. Atlas provides tailored menu-driven software for the programming and operation of each solar simulation system. Any solar simulation profile - for example morning, noon, afternoon, etc. can be stored and combined with various types of programmed test sequences for a complete integrated test program. For seamless operator interface, the Atlas designed solar control interface can be linked to the master IT environment of the test facility.
