Direct answer
Can JUNCAT support wholesale and 40HQ enquiries?
Yes. JUNCAT accepts global B2B enquiries for mainstream and custom solar modules, including full-container and repeat supply discussions. Send the destination, target model or datasheet, quantity and required shipment window. Model availability, price, MOQ, pallet loading, documents and delivery terms are confirmed in the written quotation; this page does not promise permanent stock or one universal container quantity.
Comparable quotations
Ask for these fields in one offer.
Compare the same model, currency, quantity and delivery basis. A lower price per watt does not by itself establish a better supply option.
| Model and technology | Final model number, TOPCon/HJT/PERC technology, monofacial or bifacial construction and selected datasheet revision. |
|---|---|
| Power and efficiency | Rated power, module efficiency and the electrical values needed to assess system compatibility. |
| Dimensions and weight | Confirmed module size, weight, glass/frame construction, cable and connector details. |
| Price per panel and per watt | Same currency and quoted scope. Calculate price per watt using the confirmed rated power, not an estimated bifacial yield gain. |
| EXW and FOB | Request separate quotations with the named place or China loading port, price validity and included/excluded charges. |
| MOQ and repeat orders | Trial-order feasibility, minimum quantity for the selected specification and any OEM or packaging minimum. |
| Pallet and 40HQ loading | Modules per pallet, pallet dimensions/weight, pallet count and total module count from the confirmed packing and loading plan. |
| Container power and value | Total nameplate wattage and module-only value, with freight, inspection, insurance and other agreed charges identified separately. |
| Product and performance warranty | Separate warranty periods and terms, issuer, claim route and relevant exclusions for the selected model. |
| Lead time and availability | Stock or production basis, quotation date, readiness date and estimated shipment window. |
| Payment terms | Deposit/balance basis, payment timing and conditions stated in the quotation or contract. |
| Due-diligence documents | Contracting entity, model/manufacturing information where required, datasheets, applicable test files, labels, packing list and inspection arrangements. |
Commercial starting points
Three module formats to start your comparison.
Commercial-volume supply
Compare power, module handling, construction, price basis and matching documentation together.
Review larger TOPCon formats →Utility and bifacial orders
Assess large-format TOPCon or HJT and bifacial suitability against the buyer’s layout and installation context.
Review bifacial options →40HQ loading checks
Container figures must come from the selected packing plan.
There is no universal number of solar panels in a 40HQ container. Module dimensions, pallet design, packing limits and handling requirements change the result. Mixed-model loading needs a separate confirmed plan.
Total modules
Confirmed pallet count × modules per pallet, for a uniform loading plan.
Nameplate power (kW)
Total modules × rated module power (W) ÷ 1,000.
Module-only container value
Total modules × agreed price per panel. List other quoted charges separately.

Wholesale buyer answers
Four points to clarify before ordering.
What is the MOQ for wholesale solar panels?
MOQ is confirmed for the chosen model, quantity basis, branding and packaging. Ask about trial and repeat-order options separately; no single minimum applies to every configuration.
Can I request a model that is not shown in the catalogue?
Yes. Send a reference datasheet or required power, dimensions and electrical window. JUNCAT will review a suitable supply option and identify any differences for confirmation.
Can the quotation include manufacturer information and inspection documents?
Include due-diligence requirements in the RFQ. Relevant manufacturer/model information, document scope and inspection arrangements are reviewed for the selected supply option before order confirmation.
Are a stock offer and a production offer directly comparable?
Only after checking the same model, datasheet, warranty terms, condition, quantity and delivery basis. Availability and shipment dates must be reconfirmed when accepting the offer.
