SolarConstant MHG 4000/2500

Atlas SolarConstant MHG 4000/2500 are specially designed large luminaires for solar simulation systems.

 

  • Overview +


    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 irradiance uniformity over the target area.

    SolarConstant 4000/2500 are typically used inside solar environmental walk-in and drive-in chambers for automotive applications, solar stress chambers for electronics, and for solar simulators for PV module testing.

  • Positioning System +


    To allow a SolarConstant array solar simulator to move and replicate various natural or target solar conditions, a mechanical positioning system is typically installed. This enables motorized movement of the solar array within all desired spatial directions. This allows adjustment for the size and shape of the test object and/or to simulate diurnal solar transit cycles. Atlas offers both low-cost manual remote control or full automatic alternatives that are integrated into the Atlas control system software.

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