📋 Tender Overview
Scope : To Build 5 GW Silicon Crystal and Wafer Facility in India
Solar manufacturer Renaissance Solar and Electronic Materials (RSOLEC), with operations in India and the United States, has announced it would set up a 5 GW silicon crystal and wafer manufacturing facility in India with an investment of $300 million.
The location for the manufacturing facility has not been finalized yet. The project will be commissioned by the end of 2025.
For the upcoming five years, the company’s focus will revolve around crystal growth and wafer manufacturing activities within India. After 2030, RSOLEC has plans to broaden its manufacturing operations across the entire solar value chain.
The facility will employ the Recharge Czochralski process, which can be adapted for the emerging Continuous Czochralski process for crystal growth. Wafer production will be based on the DCW platform, capable of producing thin wafers with a thickness of less than 100 micrometers.
The primary product to be manufactured will be high-quality silicon wafers characterized by low oxygen content, extended lifetime, and controlled resistivity. These wafers will be compatible with various solar cell technologies, including TOPCon, PERC, HJT, and Tandem structures.
RSOLEC is starting with silicon crystals and wafers. The entire value chain has three nodes: polysilicon production, inverted wafers, and cells & modules. They have looked at the techno-commercial case for each node and decided to start with silicon crystals and wafers. Initially, we will start with 5 GW, and as per our roadmap, we plan to take it to 9 GW by 2030.
Their commissioning will be complete by the end of 2025, and the first product will be out by early 2026. Initially, it will be silicon crystals and wafers.
Earlier, Adani Solar had introduced India’s first large monocrystalline silicon ingot at its Mundra facility. The company completed the backward integration of the ingot line infrastructure in seven months. Adani Solar plans to increase its ingot and wafer capacity by 2 GW by the end of 2023 and to further increase production to 10 GW by 2025.
