What Sunwafe does
Sunwafe is a Spain-based, pre-operational manufacturer of silicon ingots and wafers for the photovoltaic (PV) value chain, headquartered in Barcelona with a planned 30-hectare greenfield production facility in Asturias. The company was initiated in 2024 by InnoEnergy, a European clean-energy venture investor, to address Europe's structural dependency on Asian wafer imports — over 90% of global wafer production is currently concentrated in Asia — and to support the EU Net Zero Industry Act's 2030 domestic wafer production target. Sunwafe has secured a €200 million non-refundable grant under Spain's RENOVAL programme (Next Generation EU funded), representing 67% of the €300M allocated to 34 renewable-energy manufacturing projects.
The company's product line comprises silicon crystal ingots (produced via silicon purification and ingot casting) and silicon wafers (sliced using diamond-wire saws to thicknesses of 120-200 micrometers, then polished and cleaned). Wafers are offered in standard M10, G12 and G12R formats targeting TOPCon and heterojunction (HJT) cell technologies. The planned Asturias facility has a nameplate capacity of 2.5 billion wafers per year (20 GW), which Sunwafe states equals roughly 50% of Europe's projected annual wafer demand by 2030. Construction is scheduled to begin in 2027, with commercial operations targeted for early 2029 and a planned workforce of approximately 2,600 at full capacity. Tresca Ingeniería has been appointed as owner's engineer for project execution.
Sunwafe's business model is B2B hardware sales of standardized PV intermediate inputs to European and global cell and module manufacturers under direct enterprise supply agreements. The company is pre-revenue, with no publicly disclosed pricing or signed offtake agreements, and its go-to-market relies on enterprise field sales and strategic partnerships with Asian technology providers alongside its domestic build-out. CEO Michael Pinto (appointed March 2026) leads the venture, bringing 25+ years of clean-tech and industrial leadership experience from GE, Dow, Cleanwatts and Circular Materials.

Sunwafe product offering
Product offeringCore offering
Sunwafe manufactures silicon crystal ingots and wafers for the photovoltaic value chain. The company purifies silicon, melts and crystallizes it into ingots, then slices those ingots into thin wafers (150–200 micrometers thick) using diamond wire saws, followed by polishing, cleaning and surface treatment. Products are supplied in M10, G12 and G12R standard formats for TOPCon and heterojunction (HJT) solar cell technologies. Planned annual capacity is 2.5 billion wafers (20 GW), targeting direct supply to European and global PV cell and module manufacturers.
Product overview
Sunwafe is a single-product-line manufacturer focused on silicon ingot and wafer manufacturing for the photovoltaic (PV) value chain. The company's core offering consists of two integrated products: Silicon Crystal Ingots (produced through silicon purification and melting processes) and Silicon Wafers (thin slices sliced from ingots using diamond wire saws, typically 150–200 micrometers thick). Both products are designed for use in TOPCon and heterojunction (HJT) solar cell technologies. The manufacturing facility being developed in Asturias, Spain will have an annual nameplate capacity of 2.5 billion wafers (20 GW).

Products and services
- Silicon Wafers High-end silicon wafers for the photovoltaic sector, designed for top-of-range solar cells used in TOPCon and heterojunction (HJT) technologies. Standard formats include M10, G12, and G12R with thicknesses from 150 micrometers to 120 micrometers, sliced from in-house ingots using diamond wire saws, then polished, cleaned, and surface-treated.
- Silicon Crystal Ingots Silicon crystal ingots manufactured in-house through silicon purification, melting, and ingot formation processes. The ingots serve as the input for Sunwafe's wafer fabrication line and are sliced using diamond wire saws to produce thin wafers (150-200 micrometers thick) for solar cell fabrication.

Sunwafe competitors and assessment
Company assessmentBroad incumbents
- LONGi Green Energy: LONGi is the world's largest silicon wafer manufacturer and an integrated PV leader. It is the most direct global benchmark for Sunwafe's ingot/wafer business, though it operates across the full value chain at vastly larger scale and from Asia.
- Wacker Chemie: Wacker is a German polysilicon supplier that also produces silicon wafers for both semiconductor and solar applications. It is a relevant European incumbent comparable for Sunwafe on technology, customer base and EU regulatory alignment, though its primary scale is in polysilicon rather than wafer slicing.
- Trina Solar: Trina is a vertically integrated global PV manufacturer with significant in-house wafer production. It is a relevant comparable as both a competitor (in-house wafers) and as a target customer archetype for Sunwafe's B2B wafer sales.
- JinkoSolar: JinkoSolar is one of the world's largest integrated PV module manufacturers with wafer manufacturing capacity. It represents a downstream customer archetype for Sunwafe as well as a benchmark for vertically integrated competitive dynamics.
- JA Solar Technology: JA Solar is a top global PV cell and module producer with significant wafer sourcing needs. It serves as both a benchmark Asian integrated competitor and a representative target customer for Sunwafe's European-produced wafers.
Direct peers
- TCL Zhonghuan Renewable Energy: TZE is one of the top global producers of monocrystalline silicon wafers for solar applications. It is the closest direct competitor to Sunwafe in terms of product (silicon wafers) and customer base (PV cell/module manufacturers), giving the most apples-to-apples operating and pricing benchmark.
- GCL Technology Holdings: GCL is a major polysilicon and wafer producer focused on the solar value chain. Its upstream polysilicon-to-wafer integration makes it a relevant comparable for Sunwafe's wafer manufacturing economics and capacity-scaling playbook.
- NorSun (Norwegian Crystals): NorSun is a European (Norway-based) producer of monocrystalline silicon wafers for the solar industry. It is the closest geographically aligned direct peer and a leading indicator of European wafer manufacturing economics, customer demand patterns and policy support mechanics.
Emerging players
- OCI Global: OCI has historically been a major polysilicon producer and is repositioning in the solar value chain. It is relevant as an upstream neighbor and as an indicator of capital flow and strategic shifts in the silicon-to-PV value chain.
Regional players
- Meyer Burger Technology: Meyer Burger is a European-headquartered PV manufacturer (modules and cells) pursuing a premium European-made solar positioning. It is comparable to Sunwafe as a fellow European reshoring play targeting supply security and low-carbon premium pricing in the EU PV value chain.
