Solar energy is known as an important renewable energy and its exploration and utilization have become a fundamental part of sustainable development strategy. In the future, solar energy is expected to take a much more important position in all energies used by human beings. At IHS, we endeavour to provide the best solutions in the Solar Energy industry. Targeting at Solar Energy manufacturers, we have a supply chain of silicon materials and products (ingots and wafers). Polysilicon
We supply high quality virgin polysilicon manufactured by major makers, both IC grade and
Solar grade. We supply to our reliable partners to grow up ingots. Recyclable silicon scraps
We collect many different kinds of silicon recycalable materials from our patners. All materials are sorted as individual materials , conductivity type, resistivity range by our inspection and quality control team.
Solar grade ingots and wafers
We can offer many different kind of ingots and wafers as customer requirements. It's manufacturerd by our trusted partners using our silicon materials. (OEM) MONO and MULTI ingots or 125mm and 156mm wafers are available to supply. Diagram of PV supply chain, showing where IHS operates. The standard single-crystal siliconSIZE
