Wafer Thickness, TTV, Bow & Warp | Non-Contact Measurement
Learn how to calculate wafer thickness, total thickness variation, bow, and warp measurement according to ASTM.
Fab & application Certification of solar glass
The aim of condensing all assessed optical performance characteristics of a solar glass into a single value has led to the definition of the PV glass efficiency factor ηGLPV:

Unusually narrow glass panels, strips, or odd shapes can have an effect that may cause greater bow or warp than indicated above. Consult factory for bow and warp tolerance for such items.
HOW MUCH DOES GLASS BOW?
HOW MUCH DOES GLASS BOW? • Bowing is measured by placing the glass on a flat surface and measuring the highest point of deviation. • It often occurs more in larger panels or thicker
