Domestic manufacturing of high-purity quartz, silicon, polysilicon, ingots and precision wafers from one vertically integrated supplier. Made in America, made in Europe, made in Australia.
If you manufacture solar cells or modules, your biggest risk is a supply chain you can’t see and don’t control. QSM is building it: one domestic supplier for every critical input, from quartz in the ground to wafers on your line.
The QSM group is building domestic material manufacturing to enable domestic production of solar cells and panels (modules). QSM is a subsidiary of Graphene & Solar Technologies Limited (OTC:GSTX).
Made in America first, alongside made in Europe and made in Australia: high purity quartz, silicon and polysilicon produced in the markets they supply.
QSM is building the upstream half of the solar supply chain in the markets that use it: high-purity quartz sand from Ausquartz in Australia, green silicon metal and polysilicon from Southland Silicon Materials in New Zealand, and monocrystalline ingots and wafers from QSM USA in California, with further wafer plants planned for Australia and Europe.
Our anchor is the San Diego facility: a 10 GW silicon wafer plant now in execution, with production targeted for early 2027. For US cell and module makers that means wafers are made a truck ride away rather than an ocean away, with drastically reduced lead times.
Domestic production also insulates your line from the freight, tariff and policy shocks no manufacturer can control.
No Foreign Entity of Concern sits anywhere in QSM's chain. The protection for domestic manufacturers is structural: every stage is owned or controlled by the group, so the provenance of every wafer can be documented back to the mine. It also insulates buyers from the tariff and policy shocks now reshaping polysilicon and wafer imports, such as the Section 232 measures on polysilicon derivatives.
Every step is ours, so every input is traceable: from quartz in the ground to wafers on your line.
Most manufacturers buy wafers from one supplier, who bought polysilicon from another, who bought silicon metal from a third. QSM replaces that chain of unknowns with one group covering every upstream step: quartz, high-purity sand, silicon metal, polysilicon, crucibles, ingots and wafers.
For a buyer, integration means traceable inputs, a single point of accountability for quality and specification, and pricing that is not exposed to a different intermediary at every stage of production.
End-to-end control of materials and manufacturing gives buyers real negotiating power beyond the Asia-centric supply chain.
The United States needs around 62 GW of wafers a year and currently makes about 6.5 GW; the rest is imported, much of it from a single region. Domestic capacity, supported by tariff measures and incentives such as the Inflation Reduction Act and the CHIPS Act, changes the economics of buying local.
QSM gives cell and module makers a real second source with commercial weight behind it: 30 percent of San Diego's output is already committed under a 3 GW offtake agreement with a US manufacturer, and QSM USA has been awarded a $45 million California Competes Tax Credit for its two planned California plants.
Facilities across the United States, Australia and Europe, built to scale with demand.
QSM's build-out is fifteen projects across the United States, Australia, New Zealand and Portugal: five in execution and ten in planning, covering wafers, ingots, silicon smelting, polysilicon and high-purity sand.
The wafer plants are planned as repeatable 10 GW units, so capacity can be added region by region as offtake is signed. Manufacturers can start with a committed volume today and scale with the group as new lines come on.
The rest arrives by ship, exposed to freight, tariffs and policy decisions that manufacturers can’t control. QSM is closing the gap with domestic capacity at every stage of production.
QSM manufactures in the United States, with operations in California and facilities in development across Australia and Europe. Every input we produce strengthens domestic energy security and brings skilled manufacturing jobs home.
And because QSM is free of Foreign Entity of Concern exposure, the manufacturers we supply stay eligible for US government support programs that depend on it.
What sourcing from QSM means for downstream manufacturers.
Eligibility protected for customers pursuing domestic-content incentives and US government support
No foreign-entity-of-concern exposure anywhere in the supply chain, from mine to wafer
Traceable inputs at every stage, because every stage is controlled by QSM
Supply you can plan on, insulated from freight, tariff and policy shocks
