Low-iron glass for solar modules is produced using raw materials with a low iron content; consequently, it possesses higher transparency than standard float glass, allowing a greater amount of sunlight to transmit through its surface. It is primarily utilized on the front face of solar modules, where it serves to protect the solar cells from external environmental elements.
This glass maintains a relatively stable light transmittance and is compatible with the various processing methods employed in solar panel manufacturing. Depending on the specific module structure and installation requirements, it offers a wide range of processing options, including tempering, edge polishing, drilling, and corner finishing.
In numerous solar power generation projects, low-iron glass has become a widely adopted standard option, thanks to its aesthetic appeal, consistent quality, and high compatibility with automated module production lines.

Packing and loading
For export transportation, Low-Iron Glass for Solar Modules is packed with protective paper or powder between each sheet to help reduce surface scratches during movement and loading. The glass is then placed into reinforced plywood crates suitable for long-distance ocean and inland transportation.
According to different container loading requirements, MIGO GLASS can arrange customized packing methods and loading plans to improve space utilization and help reduce transportation risks. Corner protection and fastening materials are also added during loading to keep the glass stable inside the container.
Before shipment, each crate of Low-Iron Glass for Solar Modules is checked for packing condition, labeling, and loading safety. MIGO GLASS pays attention not only to glass production, but also to export packing details, helping customers receive the products in better condition after transportation.
