Eternalsun Spire products
Spire - Steady State Solar Simulator
Our next-generation LED steady-state simulator is designed to prove the stability, reliability and performance of all PV technologies, including Perovskite and Tandem.
Spire - High Performance Steady State Solar Simulator
Study performance and degradation of different PV technologies over time with our temperature-controlled A class steady-state solar simulator.
Spire - Uniformity Calibration Robot
Fast and high-resolution non-uniformity measurements of steady-state solar simulators. Light uniformity of a steady state solar simulator should be measured and calibrated regularly to maintain low non-uniformity values. The Uniformity Calibration Robot (UCR) improves the process of measuring the non-uniformity of a steady state simulator significantly over traditional methods.
Spire - Single Long Pulse Solar Simulator
Accurate & repeatable power determination of all PV types and technologies in module production lines. Spire Xenon Single Long Pulse solar simulator is designed for high volume production testing of PV modules.
Spire - Large Area Solar Simulator (LASS)
The Large Area Solar Simulator (LASS) produces class AAA+ (according to the IEC 60904-9 ed. 3), steady-state sunlight using a unique and patented technology.
