Glass-to-Glass Solar Modules:
G2G
Glass-to-Glass (G2G) solar modules refer to photovoltaic modules where both the front and back sides of the module are covered with glass. These modules typically have a layer of solar cells between the two glass sheets. The primary advantage of G2G solar modules is their durability and longevity. The front and back glass layers protect the solar cells from environmental factors, increasing the module's lifespan and making it more resistant to degradation. G2G modules are often used in harsh or demanding environments, such as deserts, where they are exposed to extreme weather conditions.
Glass-to-Backsheet Solar Modules:
Glass-to-backsheet (G2B) solar modules, on the other hand, have a glass layer on the front side and a backsheet on the rear side. The backsheet is typically a material that provides electrical insulation and protection to the solar cells. Backsheets are designed to protect the solar cells from moisture and environmental factors while also providing electrical insulation to prevent short circuits.
G2B
In summary, the main difference between these two types of solar modules lies in the material used on the back side. Glass-to-Glass modules have glass on both sides for enhanced durability, while Glass-to-Backsheet modules have a backsheet material on the rear side, which is typically a plastic or composite material. The choice between these module types depends on factors like cost, performance requirements, and environmental conditions.
