Solar Silicon Ingot CrystalsMonocrystalline and multicrystalline silicon ingot & bricks for PV Manufacturing
Silicon Ingot Materials for PV Manufacturers
Targray is a leading supplier of monocrystalline and multicrystalline solar silicon ingot crystals and bricks for commercial PV manufacturers. Committed to meeting the unique needs of each customer, we also work with our manufacturing partners to develop custom silicon ingot solutions for solar producers and technology developers with highly specific project requirements.
In both monocrystalline and multicrystalline crystallization processes, feedstock quality is a critically important issue. Focused on minimizing soft costs and increasing operational efficiency for PV manufacturers, we work closely with partners to ensure the polysilicon feedstock used to produce our silicon ingots is of the highest achievable purity and consistency.
