- the sheet diode 9 has a side length of 8-12 mm.
- the adhesive seal member having a water vapor transmission rate of less than 0.01 g/m 2 /day, in the double-glass photovoltaic module, the end seal block 3 may be a butyl rubber member or a polyisobutylene rubber member, or a water vapor transmission rate of less than 0.01 g / m 2 / day, Therefore, the deficiency of the traditional photovoltaic module edge to expose the packaging material is compensated for, and the first glass layer 11 and the second glass layer 15 which are densely packed with the upper and lower layers can well block the water vapor and corrosive gas in the environment from entering the component interior. , slow down component attenuation and extend component life.
- the double glass battery module according to the present invention has good weather resistance, high structural strength, long life, and high absorption rate for ultraviolet rays.
- the dual glass photovoltaic module according to the present invention may further comprise a plurality of fixing devices 5 disposed on a side surface of the second glass layer 15 remote from the cell stack layer 13 for use.
- the entire battery assembly is mounted to somewhere by the fixture 5.
- the back side of the battery assembly is bonded to the four fixing devices 5 by using a high-strength adhesive, whereby the fixing device 5 can be fixed to the bracket for fixing the battery assembly by screws (not shown). Out).
- This type of installation ensures a more uniform force on the battery components, enhances the ability of the components to withstand loads, and is safer and more reliable.
