Faster Quotation
Solar BOS RFQ Checklist
The information buyers can send to get faster SKU matching, lead time feedback, packing review, and export-ready quotation.
1. Product & BOM Details
2. Destination & Trade Terms
3. Technical & Market Requirements
4. Packing, Labeling & QC
Quick RFQ Template
This simple structure is enough for most first quotations. More detailed project documents can be added later during technical review.
Best practice: send one BOM file plus destination and Incoterms in the first message. It reduces back-and-forth and helps us check mixed-shipment feasibility.
| Product list / BOM | Attach file or list SKUs and quantities |
|---|---|
| Destination | Country, port, city, or warehouse address |
| Trade terms | FOB / CIF / DAP / DDP preference |
| Technical requirements | Voltage, material, coating, standards, compatibility |
| Packing requirements | Carton, pallet, labels, mixed loading, container target |
| Timeline | Required quotation date and target delivery window |
| QC request | Inspection photos, reports, loading supervision, or sample approval |
For Mixed BOS Shipments
If the order includes mounting hardware plus PV cable, connectors, protection devices, combiner boxes, distribution boxes, or storage accessories, list all categories together. OmniSol can check whether items should ship together, separately, by carton, by pallet, or as a mixed container.
RFQ Questions Buyers Ask
What should be included in a solar BOS RFQ?
A strong RFQ includes the BOM or SKU list, quantities, destination country or port, Incoterms preference, technical standards, packing requirements, target delivery date, and any inspection or document requirements.
Can OmniSol quote a mixed order with mounting and BOS components together?
Yes. OmniSol can review mixed procurement for mounting hardware, PV cables, connectors, protection devices, combiner boxes, distribution boards, and selected storage accessories.
When should buyers mention certificate requirements?
Certificate and document requirements should be listed in the first RFQ so the quoted SKU, supplier, and model can be checked against the target market before order confirmation.
How do I prepare a quote-ready solar BOM?
A quote-ready solar BOM lists every line with four things filled in: the component and quantity, the rating (voltage/current/cross-section), the certification standard required for the destination market, and the IP/enclosure where relevant. Add the destination port, Incoterms and target date at the header. With those fields complete, suppliers can quote like-for-like instead of guessing — which is the difference between a BOM that gets one comparable quote and one that returns five incompatible ones.
What makes a solar BOM "not quote-ready"?
The most common gaps are: ratings missing (just "DC isolator" with no voltage/current), no certification standard named, voltage class stated only on some lines, accessories (glands, labels, grounding) omitted, and no destination or Incoterms. Each gap forces the supplier to assume — so the quotes are not comparable. OmniSol runs a system-logic review on every BOM to flag these before quoting.
What Makes Our Quote Stand Out
Most suppliers respond to your BOM line-by-line with prices. We do something different:
System logic review
We check your BOM against system logic — flagging mismatches (e.g. 1500V cable on a 1000V inverter system) and missing items (e.g. DC isolator absent in a rooftop kit).
Alternatives proposed
Where your specified part is in short supply or carries unfavorable lead time, we propose alternatives with the spec trade-off clearly noted.
Cost category split
We split the quote into cost categories — main equipment, BoS, packaging, freight, DG handling — so you can identify which lines to negotiate or substitute.
Per-category lead time
We disclose lead time per category, not a single project lead time. Panels may ship in 2 weeks; batteries with UN38.3 batch testing may take 4–5 weeks. You see the bottleneck up front.
Payment Terms
First-order cooperation
- T/T: 30% deposit on order confirmation; 70% against Bill of Lading copy
- L/C at sight: accepted for orders ≥ USD 50,000 (irrevocable, subject to issuing bank review)
Repeat customers: terms can be adjusted after the first completed order.
Not accepted on first orders
D/P, D/A, or post-shipment payment terms. This protects both parties on initial cooperation.
Our RFQ Response Commitment
| RFQ acknowledgement | Same business day |
|---|---|
| Preliminary quote (standard BOM) | 1–2 business days |
| Structured quote with cost breakdown | 3–5 business days |
| Sample arrangement | 7–14 business days (case-by-case) |
Business hours: Mon–Fri 09:00–18:00 CST (UTC+8). For urgent timelines, add [URGENT] to your subject line for same-business-day response prioritisation.
