What is a double glass module
Photovoltaic double-glass modules refer to photovoltaic cell modules formed by two pieces of tempered glass, EVA film and solar cell silicon wafers through a laminator. (Double-glazed Solar PV module).
The early double-glass modules used standard photovoltaic glass before and after, so they were heavy and inconvenient to handle. At the same time, since the power loss caused by light leakage between cells cannot be solved, large-scale mass production has not been formed.
Compared with ordinary modules, double-glass modules have the following advantages:
1. Long life cycle
2. Has high power generation efficiency
3. Low attenuation
4. Solve the weather resistance problem of components
5. The abrasion resistance of glass is very good
6. Double glass modules do not need aluminum frame

Scope of application
What is the scope of application of double glass modules?
Double-glass modules are more suitable for photovoltaic agricultural greenhouses and sun rooms. It can also be used in fishing and light complementary projects, because the zero water permeability and corrosion resistance of double-glass modules can better solve a series of problems caused by the water surface.

how to install
How should we install the double glass module?
Double-sided double-glass module installation method: Double-glass modules are mainly installed using fixtures.
Installation video:
①When installing double-glass modules, you can use professional double-glass module clamps to install the modules. Double-glass modules need to be fixed on the photovoltaic support with aluminum alloy pressing block fixtures. Length: The length of the clamping fixture should be greater than or equal to 100mm.
Compression block material: aluminum alloy
Rubber strip: EPDM rubber
Bolt: M8 stainless steel
Torque range: 16-20 N.m
②In any case, the pressure block fixture cannot deform the component. The aluminum alloy pressure block fixture needs to be used with an embedded rubber gasket to play a buffer role to avoid unknown damage to the component and the aluminum alloy pressure block fixture.
The contact surface of the double-glass module clamp and the module must be flat and smooth, otherwise the module will be damaged. It is important to avoid the shading effect of the fixture.
