Polysilicon Technology & Owner's Engineering — Frequently Asked Questions
The questions owners, developers, investors, and lenders ask us first — answered honestly, without marketing gloss.
If it's not here, ask us directly.
The questions below are the ones we actually receive, in order of frequency. If you don't see your question, the fastest path is a 30-minute confidential scoping call. We don't charge for the first conversation.
Is NEXARSiL a licensor or a consultant?
Both, deliberately. NEXARSiL licenses its own electronic grade (9N to 11N) polysilicon technology package, and it also runs a completely separate owner's engineering practice that supports owners working with any licensor. The two roles operate behind a strict internal firewall and a written disclosure is provided to every owner's engineering client.
What purity levels have you actually demonstrated?
Semiconductor-grade 11N (99.999999999%) in commercial operation. We also routinely support solar-grade plants across the 6N–9N range. All numbers are from real plants, not lab runs. Commercial operating evidence and supporting technical details may be reviewed under NDA with qualified owners, investors, or project partners.
What services do you offer?
Eight core services: technology evaluation and licensor selection, feasibility studies, owner's engineering, plant design and engineering review, CAPEX / OPEX optimization, operator training, construction quality and cleanliness, and licensing of our own technology package.
Do you work with solar-grade producers or only semiconductor?
Both. Many solar-grade producers are now moving toward electronic-grade output, and we support that transition. We also work with developers targeting pure solar-grade projects where the economics are different.
Can you work on existing plants, or only greenfield?
Both. We run de-bottlenecking, purity uplift, and operational troubleshooting programs on existing plants. Brownfield and greenfield are roughly equal in our engagement mix.
How long do engagements typically take?
A focused decision memo can run three to six weeks. A full feasibility study is eight to twelve. Owner's engineering programs span the life of the project. We size the team and the scope to the decision being supported.
How do you handle confidentiality?
NDAs are the default. We work with plant owners, investors, lenders, and government programs where privacy is a baseline expectation. No reference is ever provided without explicit written permission from the referenced client.
Can you help us select a licensor other than NEXARSiL?
Yes. That is exactly what our technology evaluation service does. On request we exclude the NEXARSiL package entirely from the evaluation to remove any appearance of conflict. We provide honest pro's and con's between the two as well.
Are your feasibility studies bankable?
Yes. We structure feasibility studies so that lenders and development-finance institutions can use them as part of their own due diligence.
Do you take vendor commissions?
No. Never. If we recommend an equipment vendor, it is on engineering merit alone, and we will not accept any commission or referral fee from that vendor.
How do I start a confidential discussion?
Through the contact page or a direct email. The first conversation is a no-obligation scoping call under an informal NDA, and we move to a written NDA before any sensitive information is exchanged.
Verification Under NDA
What we publish on this website is limited by confidentiality agreements with the owners, developers, and investors we work with. The evidence behind our experience exists — it is simply not ours to publish without permission.
What can be reviewed under NDA
Qualified project owners, investors, lenders, and partners may review: operating experience records, product quality data, process design basis, commissioning records, operator training materials, acceptance criteria, and project execution documentation.
What we do not publish
No client names, plant throughput figures, customer relationships, or confidential project data are published on this website without explicit written permission from the party that owns that information.
To arrange a structured NDA review, contact us through the form below. We provide a mutual NDA and schedule a technical review session within a few business days of a qualifying request.
