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 solar simulators for measuring the performance of PV Solar Modules. The flash simulator’s world-class capabilities – regarding spectrum, uniformity and stability – provide research and test laboratories, as well as PV module manufacturers, an instrument that is unparalleled in measurement quality.

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.

Our flagship product, the Spi-Sun Simulator™ 5600SLP Blue, is the industry standard in module performance testing. It is now used by more than 30 standards testing laboratories worldwide. Our one-lamp 5100SLP Blue is a staple in mass production lines around the globe.
