Silicon in.Solar-grade wafers out.
Silvarasemicon is building an integrated plant that takes polysilicon through ingot growth, precision slicing and finishing, and supplies wafers to solar cell manufacturers.
- N-type mono-crystalline wafers
- M10 and G12 formats for current cell lines
- One site from polysilicon to finished wafer
From sand to silicon to solar wafer
Follow silicon from refined silica sand to the finished wafers that cell makers load into their lines.
One roof, one quality standard
Silvarasemicon was founded in 2026 in Ahmedabad, Gujarat, to build an independent ingot-and-wafer plant. Our mission is to make the wafer, the most import-dependent part of a solar panel, here in India. We focus only on n-type mono-crystalline wafers for high-efficiency TOPCon and HJT cell lines.
We put crystal growth, slicing and finishing under one roof so that purity, thickness and surface quality are controlled at every stage.
We are built on three commitments: quality traceable from every ingot to every wafer, a dependable domestic supply for India's cell makers, and responsible use of energy, water and silicon.
We serve solar cell and module manufacturers who need consistent wafers at volume, and investors backing the build-out of domestic solar supply chains.
Why India needs domestic wafers
India can now make 233 GW of solar modules and 42 GW of cells a year, but only about 8 GW of ingots and wafers, so most wafers are still imported. From June 2028, ALMM List-III makes India-made wafers mandatory for covered projects, while demand keeps climbing as new cell lines come online.
Where India stands today
Annual manufacturing capacity, June 2026
Wafer demand vs domestic supply
GW per year. Demand equals India's cell capacity, since every cell is made on a wafer.
From polysilicon to finished wafer in four stages
Every stage is traceable. Inspection data follows each ingot through to the wafer cassette.
Polysilicon feedstock
High-purity polysilicon is sourced, verified on arrival and prepared for the crystal puller.
Ingot growth
Czochralski growth produces mono-crystalline ingots with controlled resistivity and oxygen content.
Wafer slicing
Ingots are squared and cut with diamond wire for thin wafers, low kerf loss and tight thickness variation.
Finishing and QC
Wafers are cleaned and inspected for thickness, TTV and micro-cracks, then cassette-packed to order.

Why partners choose Silvarasemicon
Integrated supply
Fewer hand-offs between suppliers means shorter lead times and a single point of accountability.
Cell-ready quality
Wafers are matched to n-type and high-efficiency cell processes from the start, not retrofitted.
Scalable plant design
Furnace and slicing capacity is planned in phases so output can grow with demand.
Responsible operations
Energy, water and silicon recovery are designed into the plant to cut cost and footprint.
