A Spire Gives You ConfidenceIn the past decades Spire Solar sun simulators have built a proven track record. The unique benefits of a single long pulse and our enhanced spectrum assures accurate, reliable and repeatable measurement results for PERC and other PV technologies.
Spi-Sun Simulator™ 5100SLP BlueOur 5100SLP blue offers a measurement repeatability of < 0.15%, Class A+ uniformity, class A+ 300nm-1200nm spectrum, guaranteed maximum power with Single Long Pulse (SLP) up to 100ms, and reduced total cost of ownership.
Single Long PulseSingle Long Pulse (SLP) testing is preferred to achieve a robust and straightforward measurement for new technologies (PERC, HJT). No black box and result tuning, the user is in control. Accurate, no physical effects of manipulated voltage ramping as with short 10ms flash.
"Blue". The Standard in PV Power MeasurementThe upgraded Spi-Sun Simulators™ 5600SLP Blue and the 5100SLP Blue provide an extended A+ Class spectrum which truly mimics the sun well beyond the blue end of the visible spectrum.
Providing High-Quality Solar Simulation Worldwide
Spire Solar is a leading manufacturer of solar simulators for measuring the performance of PV solar modules. Our mission is to play a critical role in developing a global solar industry which can compete with the full range of energy sources in today’s demanding energy environment.
We do this by providing world-class flash simulators with renowned capabilities regarding repeatability, reproducibility, spectrum, uniformity, and stability to PV solar module manufacturers, as well as research and test laboratories.
Single Long Pulse
Spire’s solar simulators use proven Single Long Pulse (SLP) flash technology to accurately measure the performance of a PV module. This enables longer sweep times while preserving the reliability and ease of use of a traditional flash tester.
