Specification
Same model code, same STC watt class, same efficiency percent, same maximum system voltage of 1000 V or 1500 V.
VoltPoint Procurement sends one written requirement to solar module manufacturers so watt class, efficiency basis, connector, quantity, and destination stay fixed while quotations come back. The desk is an independent sourcing partner. It does not operate a laminator, claim authorization, or treat a brochure as a listing.
Standard Test Conditions mean 1000 W/m2 irradiance, 25 C cell temperature, and the AM 1.5 reference spectrum. A rating under another condition belongs in a separate comparison column. A 540 W to 600 W band is an illustrative request, not a stocked rating. Module efficiency belongs in percent beside its test basis. Open-circuit voltage and maximum power voltage belong in volts.
Same model code, same STC watt class, same efficiency percent, same maximum system voltage of 1000 V or 1500 V.
Same piece count and pallet multiple. A 28-piece pallet does not equal a mixed container unless the brief says so.
Same Incoterm, currency, and US destination. Freight, duties, and spare leads stay inside or outside the price together.
Datasheet, drawing, and flash list for the quoted serial range. ISO 9001 scope is requested for that factory, not borrowed from another plant.
Ask for the datasheet revision dated on the file, the outline drawing with frame holes, the flash-test list for the lot, and the UL 61730 or IEC 61215 edition the factory cites for that model. The U.S. Department of Energy page reviewed on 2026-10-26 only explains system parts. It does not list accepted models.
A family brochure, a certificate for a different watt class, or a photo of a nameplate is not the file set. Sample modules, if requested, need the same model code as the quotation.
Agree the sample quantity, cost, destination, inspection method, and acceptance criteria before shipment. Compare the sample label, dimensions, connector, and serial range with the quoted drawing and flash list; have a qualified reviewer assess electrical results. Request production MOQ and timing separately from sample timing. Rank a lower unit price only after freight, duties, accessories, and warranty exclusions match.
String current, DC-to-AC ratio, and inverter match stay with the electrical designer. Racking clamp zones stay with the structural reviewer. Interconnection voltage class stays with the utility package. VoltPoint Procurement can show where those answers are missing. It does not stamp them.
Cell technology labels such as PERC, TOPCon, or HJT are recorded as the buyer wrote them. The desk does not rank those labels or predict annual energy. Bifacial gain, if any, must name its albedo and test method or remain blank.
Read the inquiry options, then use the contact form or the procurement brief.
Product, quantity, destination, per-module or whole-order budget, and supplier preference travel in the requirement text. FREE sourcing support may be up to 3%. Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements.
