PV: mechanical treatment of glass
The glass is placed on ceramic rollers that transport it through the tempering furnace, where it is heated to a temperature between 600°C and 700°C, close to its softening

Discover the critical factors of glass behavior: thermal expansion, transition, and softening points. Enhance your understanding with our detailed analysis!
An optimal solar cover glass exhibits a softening point at least 700 °C—well above processing and service temperatures—ensuring structural and optical integrity over 25+ year lifecycles.
We measure it using a temperature gradient furnace with glass placed in a platinum or ceramic boat and held for the required time. Test times are

The strain point refers to the temperature at which internal stress in the glass can be relieved within a few hours without causing distortion, even when
Sudden cooling of a glass surface below the average specimen temperature, Ta, causes the development of tensile stresses which can lead to glass fracture by thermal shock.

The strain point refers to the temperature at which internal stress in the glass can be relieved within a few hours without causing distortion, even when the glass is rapidly cooled.
The softening point is the temperature at which glass begins to deform under its own weight. This occurs when the glass reaches a viscosity of about 10^7.6 Poise (10^7.6
The Littleton softening point (T s) of glass is the temperature at which the glass moves under its own weight. As a glass is heated, the glass flows more easily.
Controlling the softening temperature of glass frit and improving the wettability and high-temperature viscosity of glass frit is the key to enhance the reliability of PV module
Defined by ASTM C338, the softening point is the temperature at which a standard-diameter glass fiber deforms at a controlled rate under its own weight—typically around 0.2 mm/min.
