4 FAQs about Double glass module attenuation rate
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.
What is the encapsulation reliability risk of double glass module?
The double glass module is superior to the conventional single glass module, which indicates that the encapsulation reliability risk of double glass module is good without delaminating risk. 90 Jing Tang et al. / Energy Procedia 130 (2017) 87–93 4 J. Tang et al./ Energy Procedia 00 (2017) 000–000 Fig. 3.
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.
