Providing High-Quality Solar Simulation Technology Worldwide
PV Solar Module testing plays a critical role in developing a mature, global solar industry which can compete with the full range of other energy sources in today’s demanding environment.
Spire Solar is a leading manufacturer of sun simulators for measuring the performance of PV Solar Modules. The simulator’s world-class capabilities – regarding spectrum, uniformity and stability – provide research and test laboratories, as well as solar module manufacturers, an instrument that is unparalleled in measurement quality.
SLP Solar Simulation
Spire’s solar simulators use proven Single Long Pulse (SLP) flash technology to accurately measure the performance of a PV module. This type of illumination enables longer sweep times while preserving the reliability and ease of use of a traditional flash tester.
Our flagship product, the Spi-Sun Simulator™ 5600SLP, has become the industry standard in module performance testing. It is now used by more than 30 standards testing laboratories worldwide and is a staple in mass production lines around the globe.Learn more about sun simulation...
