In the asymmetric glass-foil module design, the glass sheet is the dominating mechanical layer, with by far the highest specific thermal expansion stiffness (52 ). Therefore, its properties determine the PV modules deflection in mechanical load. At least one stiff layer is needed.
The maximum deformation of long side is tested according to the mechancial load of +5400 Pa for DH1000h, and -5400 Pa for DH2000h. Test result is that double glass module has no problems such as bubbles and delamination after tested under the condition of distortion +DH2000h, and the power loss is 2%.
In the glass transition, the coupling of the solar cells to the encapsulant and front- and backsheet increases suddenly, which reduces the maximum stress in the solar cells, as described above. This also influences the PV module bending, as the deflection at 0 Pa in Figure 12 shows.
At least one stiff layer is needed. The large difference of the specific thermal expansion stiffness to the solar cells value of 1.5 is also the reason why the glass'' height has almost no influence on thermal stress in the solar cells. Differently, the front- and backsheet CTE strongly influences the thermal stress.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
