A practical solar module procurement guide.

Use this checklist to turn a broad requirement into a quote that can be compared, documented and confirmed for a real B2B order.

Direct answer

What should a solar module RFQ include?

A useful RFQ identifies the destination market, application, target module or reference datasheet, quantity, required timing, construction preferences and documentation needs. JUNCAT can discuss mainstream or buyer-defined module formats, but the final model, manufacturing route, datasheet, bill of materials, certification scope, warranty issuer, packaging and delivery terms are confirmed in writing for the selected order.

RFQ checklist

Send six facts before asking for a firm comparison.

These inputs help prevent a low headline price from hiding a different construction, document scope or delivery basis.

01 / MARKET

Destination market

State the country and, when relevant, the city or region, importer route and delivery destination.

02 / USE

Buyer role and application

Identify whether the requirement is for distribution, rooftop, C&I, utility, replacement or private-label supply.

03 / TARGET

Technical reference

Send a target power class, dimensions, cell format, voltage window, tender sheet or buyer reference datasheet.

04 / VOLUME

Quantity and timing

Share the trial quantity, container or project volume, expected order date and required arrival window.

05 / BUILD

Construction and OEM

Note glass, backsheet, frame, cable, connector, colour, label, carton and private-brand requirements.

06 / DOCUMENTS

Documents and trade terms

List required test or certification scope, inspection needs, Incoterm and any importer-specific files.

Confirmed before order

The final supply basis.

  • Manufacturer model and final datasheet
  • Electrical values, dimensions and construction
  • Applicable documents and warranty issuer
  • OEM appearance, packaging and delivery terms
Provisional during sourcing

What should not be assumed.

  • Website power ranges are not permanent stock
  • A certificate is not universal across every model
  • A reference image is not final product approval
  • Lead time and price require a defined RFQ
Quote comparison

Compare the complete supply basis, not watts alone.

Two modules with the same headline power may differ in electrical design, construction, documentation, warranty responsibility and logistics.

ElectricalRated power and tolerance; Voc, Isc, Vmp and Imp; maximum system voltage; series-fuse rating where applicable.
PhysicalDimensions, weight, glass and backsheet or dual-glass build, frame, cable length, connector and junction-box arrangement.
PerformanceEfficiency, temperature coefficient, degradation terms, bifaciality and mechanical-load values when relevant to the selected model.
DocumentsFinal datasheet, label, packing list, inspection plan and the exact model or factory scope covered by requested test or certification files.
CommercialQuantity basis, price validity, Incoterm, payment terms, lead time, pallet and container loading, and destination charges.
ResponsibilityContracting company, manufacturer identity where required, warranty issuer, claim route and agreed after-sales documentation.
Regional checkpoints

Climate, logistics and destination documents belong in the RFQ.

Do not select a module from country name alone. Record the actual installation environment, buyer route and required document scope.

Hot & dusty

State temperature context, soiling, cleaning approach and construction preference.

Coastal & corrosive

Identify salt exposure, humidity, frame and connector considerations, and requested test files.

Tropical & humid

Clarify moisture exposure, installation type, PID concerns and packaging conditions.

Cold, snow & wind

Provide the site load basis, mounting context, dimensions and model-specific mechanical values needed.

Traceability-sensitive

List importer, label, origin, supply-chain and destination-document requirements before selecting the route.

Restricted logistics

Confirm handling limits, pallet preference, container loading, port and final delivery constraints.

Direct answers

Common procurement questions.

Short answers to the questions buyers most often need resolved before a useful quotation can be prepared.

Can JUNCAT supply a model that is not in the catalogue?

Yes. Send the reference datasheet, tender requirement or target dimensions and electrical window. JUNCAT will review an appropriate supply route and confirm the final model and documents for the enquiry.

Are the website power ranges fixed stock?

No. They are sourcing references used to identify a suitable technology and format. Availability, final power and commercial terms are confirmed against the actual quantity and timing.

Can certification files be provided before an order?

The required scope can be reviewed during quotation. Applicable files are matched to the selected model, manufacturing route and destination; they are not represented as universal across all configurations.

What is the fastest way to receive a relevant quote?

Send one message containing the destination, application, reference specification, quantity, required date, document needs and OEM or packaging requirements.

Prepare your RFQ

Send the target specification directly on WhatsApp.

Include the destination market, quantity and required timing. Attach a datasheet, tender sheet, drawing or customer requirement if one is available.
