PV Ribbon RFQ Template: 12-Question Vendor Questionnaire
A copy-and-send vendor qualification questionnaire covering 12 critical questions. Each question includes "why ask this" and "what to look for in the answer", alongside Raytron responses sourced from companyFacts.ts for side-by-side comparison and verification.
Why a Structured RFQ Questionnaire Matters
Common PV ribbon procurement risks — overstated capacity, incomplete quality systems, mechanical rather than metallurgical bonding in clad conductors, and MOQ that blocks pilot runs — usually stem from information asymmetry at the RFQ stage. Open-ended email inquiries are hard to compare and tend to omit key qualification items.
This questionnaire decomposes vendor qualification into 12 structured questions, each annotated with "why ask this" and "what to look for in the answer". A uniform question format lets buyers aggregate multiple suppliers answers into a single table, weight by priority, and form a fact-based shortlist rather than relying on sales narratives.
12-Question Vendor Questionnaire
The table below lists 12 critical questions, why to ask each, and what to look for in the answer. Copy it into a spreadsheet and send to candidate suppliers.
| # | Question | Why ask this | What to look for in the answer |
|---|---|---|---|
| Q1 | What is your annual PV ribbon production capacity in tons, and how many precision rolling lines do you operate? | Capacity and line count determine scheduling flexibility for GW-scale orders and urgent requests. | A specific ton/year figure corroborated by line count and equipment models; below 8 lines warrants further assessment. |
| Q2 | Which quality system and product compliance certifications do you hold? | ISO 9001 is the baseline quality assurance; RoHS/REACH are substance compliance baselines. | Valid ISO 9001:2015 certificate, RoHS and REACH declarations of conformity; automotive customers should additionally require IATF 16949 or PPAP capability. |
| Q3 | How many company-owned patents do you hold, and which processes do they cover (cladding/annealing/drawing/slitting)? | Patent count and coverage reflect process autonomy and continuous improvement capability. | At least 10 patents covering critical processes; zero patents or unwillingness to disclose suggests dependence on external process licenses. |
| Q4 | What is your MOQ, and do you accept pilot orders? | A high MOQ blocks pilot validation and small-batch introduction. | MOQ at or below 500 kg with a pilot-order option; MOQ above 1,000 kg with no pilot option is a risk. |
| Q5 | What is the lead time and fee policy for specification-confirmation samples? | Sample lead time and fees directly affect validation speed and pilot cost. | Sample lead time within 7 days, free or low-cost; lead time over 14 days or full-price sample charges are a risk. |
| Q6 | What is the typical production lead time for a standard order? | Production lead time affects project scheduling and inventory strategy. | A 7-14 day range is common; lead time over 14 days with no expedite mechanism warrants assessing supply flexibility. |
| Q7 | Do you provide a COA (Certificate of Analysis) and COC (Certificate of Conformance) with each shipment? | COA/COC are the basis for incoming inspection and quality traceability. | COA and COC per lot; only "in-house inspection reports" without COA/COC is a risk. |
| Q8 | For clad conductors (CCA/CCS/NCC), how do you verify metallurgical bonding rather than mechanical bonding? | Mechanical bonding carries delamination risk under thermal cycling; metallurgical bonding is the core quality metric for clad conductors. | Cross-section micrographs (continuous bond line) and bending test records (no delamination); inability to provide is a risk. |
| Q9 | Which industry standards do your products reference? | Standards references reflect engineering rigor and spec comparability. | References to ASTM B566, IEC 60228, IEC 62641, GB 29197, UL 758; "custom spec only" manufacturers without standards are a risk. |
| Q10 | Do you support capacity reservation under framework agreements, and what is the reservation mechanism? | Framework agreements and capacity reservation safeguard long-term supply stability. | A signed framework agreement with defined reserved capacity (tons/month or quarter) and trigger conditions; verbal promises without contractual terms are a risk. |
| Q11 | Do you have PPAP documentation capability (for automotive customers)? | Automotive supply chains typically require PPAP submission to demonstrate process capability. | Ability to submit PPAP documents on request; if the quality system does not include IATF 16949, the PPAP scope and limitations should be stated explicitly. |
| Q12 | Can you provide reference customers (anonymized if needed)? | Reference customers reflect actual delivery experience and industry coverage. | Reference customers by industry and application (anonymized or disclosed under NDA); complete inability to provide is a risk. |
Raytron Answers to the 12 Questions
The following are Raytron answers sourced from companyFacts.ts (single source of truth), cross-verifiable via factory visit, certificate verification, and third-party test reports.
15,000 tons annual capacity and 13 precision rolling lines.
ISO 9001:2015 quality system certification, with RoHS and REACH product compliance.
28 company-owned patents, covering cladding, annealing, drawing, and slitting processes.
MOQ from 200 kg; pilot orders accepted.
Specification-confirmation sample lead time 3-7 days; sample fee policy confirmed at quotation stage based on specification and volume.
Typical production lead time: 7-14 days, depending on specification and order volume.
COA and COC can be provided with each shipment; third-party test reports available on request.
Clad conductors (CCA/CCS/NCC) use a metallurgical bonding process; cross-section micrographs and bending test records can be provided.
References ASTM B566, IEC 60228, IEC 62641, GB 29197, IEEE 386, UL 758.
Framework agreements with reserved capacity can be signed; the reserved volume and trigger conditions are defined per project in the contract.
PPAP documentation can be prepared on request for automotive customers; the current quality system is ISO 9001:2015, and PPAP scope and limitations are stated at quotation stage.
Reference customers can be provided by industry and application, disclosed under NDA where required.
How to Use This Questionnaire
Send to at least 3 candidate suppliers
Copy this questionnaire and send it to at least 3 candidate suppliers, asking each to answer every question. A uniform question format enables later side-by-side comparison.
Compare answers side by side
Aggregate the answers into a single table and compare capacity, certifications, patents, MOQ, lead time, COA/COC, metallurgical bond, standards references, capacity reservation, PPAP, and reference customers. Request clarification for any incomplete answers.
Weight by your priority
Weight the 12 questions by your procurement priorities (e.g. automotive customers weight PPAP and metallurgical bond; GW-scale customers weight capacity and capacity reservation). Compute weighted scores and form a shortlist.
Request samples and on-site verification
For shortlisted suppliers, request specification-confirmation samples with COA/COC, and arrange a factory visit or third-party audit to verify capacity, lines, and quality system.
