2202 Silicon Metal Lumps 5-10 mm

Silicon Metal 2202 is an important material in the worldwide move towards sustainable energy. It can make renewable energy systems more efficient and durable. In solar photovoltaics, grade 2202 silicon is refined into polycrystalline ingots, which are sliced into wafers and processed into solar cells. These cells are 20–22% efficient, which is important for making solar electricity cheaper.

 As a factory-direct provider, we cut costs by removing intermediaries, offering free samples, technical guides, and lab/industry reports to help you select the right grade (441, 553, etc.) for your renewable energy or industrial application.

 With 30 years of experience, 1.5 million tons annual output, and 300 staff, we maintain ample stock to fulfill urgent orders and customize products (e.g., particle size, alloy composition) to your unique needs, ensuring alignment with your project timeline.

  Our four-tier quality control-including spectral and chemical tests on raw materials, in-production batches, and final products-ensures unmatched consistency, minimizing risks in your supply chain and keeping your operations on track.

We prioritize your success: our metal silicon is packaged in 10kg/25kg waterproof bags within 1MT bulk sacks (or custom packaging) to protect against moisture, while our 24/7 order tracking system provides real-time visibility, and our after-sales team resolves queries within 24 hours, guaranteeing a partnership built on trust.
