What is the light transmission of double-sided double-glazed modules?

Very good, the gain effect on the back of the bifacial module is significant, effectively reducing the electricity cost.

In terms of efficiency, bifacial modules can absorb ground reflected light and refracted light to achieve simultaneous front and rear power generation. The rear photoelectric conversion efficiency is about 60% to 90% of that of the front, so overall more efficient power generation. According to LONGi's external operations in three locations around the world.

Double-sided modules are designed to allow the back side of the module to also generate electricity. So they will use transparent materials, which can be transparent backsheets, but usually come in the form of double glass.

Double-sided double-glazed modules have many advantages, including the following aspects.

1. The vThe photovoltaic battery itself has very long durability and lifespan. Compared with photovoltaic backsheets, there is no need to add film to the outermost layer of the backsheet to ensure the efficiency and service life of the module. . At the same time, the barrier properties of glass are also very good and the moisture resistance ability is good, which further ensures the effectiveness of the components.

2. The double-sided glass module has a symmetrical structure and good weight consistency, which can effectively improve mechanical strength and better protect battery cells.

3. The use of materials is simpler. Only three materials are used in the five-layer structure, which will help reduce costs and solve recycling issues in the future.

4. Double-sided glass modules do not require frames, which can avoid the increasemodule costs caused by the rise in metal materials. Double-sided double-glass modules also meet the development trend of BIPV, ensuring indoor lighting while increasing electricity generation.

Double glass solar panels are good.

1. Double glass solar cycle. Double glass modules have a higher energy production capacity during their life cycle, 21% higher than ordinary modules.

2. Single glass solar panel cycle. The guarantee is that the attenuation is 0.7% for 25 years, so the seismic resistance is poor.
