Spire Corp. says it has introduced a new advanced metrology product, the Spi-EL Electroluminescence Solar Module Tester.
The Spi-EL series of solar module testers use electroluminescence to identify microcracks and other invisible defects in modules, as well as utilize cooled near-infrared charge-coupled device camera technology to image each solar cell with resolutions less than 200 um per pixel, or the equivalent of a 60-megapixel image for an entire module, Spire explains.
