The Laser Edge glass reportedly eliminates micro cracks and increases yield. Cutting glass using the proprietary Zero Width Laser Cutting Technology (ZWLCTT) increases the strength and longevity of the glass by creating a controlled micro crack on the molecular level. This micro crack, or scribe line, separates the molecules inside the glass and a breaking machine is used to force the glass to split along the scribe lines with no material loss, no chips or debris.

ZWLCTT can be used for precise glass separation at high production speeds, leaving quality edges, according to the company.  The processed glass is 4 to 5× mechanically stronger and has defect-free edges without additional edge processing. It is said to increase solar panel lifespan and increase reliability in extreme temperature environments.
