Polysilicon plant services, delivered from inside the plant.
Eight services. One standard. Every engagement is owner-side, vendor-neutral, and grounded in 25+ years of real production experience — not theory.
Every service is delivered by engineers with real polysilicon production experience.
NEXARSiL's services are structured around the decisions polysilicon plant owners and developers actually make — from the first feasibility question through steady-state 11N output. Each service can be engaged standalone or bundled inside a full lifecycle program. Every engagement is vendor-neutral: we do not take equipment commissions or licensor referral fees.
Technology Evaluation & Licensor Selection
Independent comparison of polysilicon licensors across process, purity, CAPEX, OPEX, and commercial terms.
Learn more →Feasibility Studies
Pre-FID studies with technical, commercial, and financial depth — written for boards, lenders, and government sponsors.
Learn more →Owner's Engineering
Fully independent owner-side engineering team supporting any licensor, from FEED through first-qualified output.
Learn more →Plant Design & Engineering
Detailed design review, P&ID hardening, reactor layout, utility integration, and high-purity specifications.
Learn more →CAPEX Optimization
Line-by-line CAPEX review that removes margin stacking and unnecessary redundancy without sacrificing purity or uptime.
Learn more →Operator Training
Classroom and on-plant training built around real Siemens CVD operating experience, not generic materials.
Learn more →Construction Quality & Cleanliness
QA/QC and cleanliness regimes specifically engineered for polysilicon purity targets. Where most plants lose yield.
Learn more →NEXARSiL Technology Package
Our own demonstrated 11N Siemens-CVD polysilicon process, available as a complete licensed package.

Every engagement, regardless of scope, follows the same five steps so owners know exactly what they're buying and what they'll receive.
Scope
Confidential scoping call. We define the decision the owner actually needs to make, the timeline, and the constraints. No proposal before we understand the real question.
Baseline
Document review, site walk-down if applicable, and baseline data analysis. We bring hard numbers — operating logs, purity data, historian trends — into the picture before opinions.
Analysis
Engineering analysis against benchmarks from real operating plants. Not textbook assumptions — numbers that match what your plant will see in week one of operation.
Decision memo
A single, board-ready decision memo with the recommendation, the alternatives considered, the risks, and the numbers behind them. Short. Executive-friendly. Defensible.
Implementation support
Optional but usually taken. Engineering presence through implementation, commissioning, and first-qualified output. We stay until the plant is making spec material.
Tailored for four specific buyers.
Plant owners
Existing producers targeting de-bottlenecking, purity uplift, or operating-cost reduction on running assets.
Project developers
Greenfield and brownfield developers from pre-feasibility through FID and execution.
Investors & lenders
Independent technical due diligence for debt, equity, and development-finance transactions.
Strategic & government
National polysilicon programs and supply-chain localization initiatives. Discreet by default.
Questions we often get about this
Can I engage just one service or do I have to commit to the full arc?
Single-service engagements are the norm. Many owners start with a targeted technology evaluation or feasibility study and expand scope only once they're confident in the team. There is no bundled commitment.
How long does a typical engagement take?
A focused decision memo can take as little as three to six weeks. A full feasibility study or owner's engineering program spans the project timeline. We right-size every engagement to the decision it supports.
Do you support plants that have already selected a licensor?
Yes — this is one of the most common engagements. Our owner's engineering team steps in alongside an existing licensor to represent the owner's interests through design review, construction, commissioning, and ramp-up.
