Double glass component shift

What is double glass PV module?

Double glass PV module is known as the ultimate solution for the module encapsulation technique. Although double glass modules have many advantages, they are not yet widely used in photovoltaic power plants, for which one important reason is the large power loss due to the transmission of light in the cell gap region.

What is a double glass module?

Double glass module contains two sheets of glass, whereby the back sheet is made of heat strengthened (semi-tempered) glass to substitute the traditional polymer backsheet. With * Corresponding author. Tel.: +86 13776101913; fax: +86 51268961413.

Does double glass module have bubbles and delamination?

The test result (Fig. 5) shows that the double glass module has no obvious appearance abnormalities such as bubbles and delamination after this sequence test, and the power loss of the module is smaller than 5%.

Why is white double glass PV module more powerful than transparent?

Due to the high reflectance of white EVA, the power of white double glass module is higher than that of transparent double glass module by 2-4%. Double glass PV modules is an area of significant investigation by many companies and institutes in recent years, for example Dupont, Trina, Apollon, SERIS, MIT, Meyer Burger and Talesun.

What is the maximum deformation of a double glass module?

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%.

Does double glass module lose power after aging?

The test result (Fig. 4) shows the power loss of double glass module is small after aging, less than 5% and there is no abnormality in appearance and insulation performance. Fig. 4. Power attenuation after dynamic load + shear sequence test.
