Photovoltaic panel glass curvature standard
The life cycles of glass-glass (GG) and standard (STD) solar photovoltaic (PV) panels, consisting of stages from the production of feedstock to solar PV panel utilization, are
Cristacurva's internal standards for flatness in FLAT tempered glass products are limited to a 0.006” (0.15mm) differential as measured with a roller-wave gauge (Figure 14). There will be some roll distortion that exists in all heat-strengthened and tempered glass products, and the viewing angle will exaggerate these effects.
This slight lack of curve consistency is particularly noticeable when affixing two radial glass pieces end-to-end – such as with handrails. In curved tempered laminated glass products with holes, one hole will always be 1/8” larger in diameter than the other one.
In curved tempered laminated glass products with holes, one hole will always be 1/8” larger in diameter than the other one. The customer needs to make sure that the smallest hole diameter drilled on the glass is at least 1/8” larger than the gasket going into it so that the hole alignment tolerance is correctly taken into account.
If your project requires for a glass with a more specific buildup, please: What key parameters define the optical properties of photovoltaic glass? The key optical parameters are the Visible Light Transmission (VLT) and the Solar Factor (g-value). The VLT indicates the amount of light passing through the glazing.
