Multi-container and MW-scale orders are quoted manually — volume, delivery window and freight optimized per project.
N-Type TOPCon (Tunnel Oxide Passivated Contact) delivers measurably better performance than P-Type PERC across the metrics that drive project economics: higher module efficiency, lower temperature coefficient, stronger bifacial gain, and a steeper long-term degradation curve.
For EPCs and developers where BOS, racking, and labor are fixed costs, higher-wattage TOPCon modules reduce module count, cut installation labor, and improve energy yield per dollar invested — making TOPCon the preferred technology for bankable utility and C&I projects.
Reserve TOPCon inventory or submit an RFQ for your commercial or utility-scale project. Pallet pricing is public — container pricing via RFQ.
TOPCon (Tunnel Oxide Passivated Contact) is an N-Type silicon solar cell technology that achieves higher efficiency than conventional PERC cells. By passivating the rear contact with a thin tunneling oxide layer, TOPCon modules deliver higher power output, better low-light performance, lower temperature coefficient, and a steeper degradation curve — all critical for commercial and utility-scale project economics.
SolarStock USA stocks multiple Sunpro Power, Mission Solar, Waaree, and ZN Shine TOPCon N-Type SKUs across a range of wattages. Current in-stock configurations and live availability are shown above. 86.53 MW of TOPCon stock is landed in U.S. warehouses and ships without import delays. A further 144.4 MW is in transit (arriving Oct–Nov 2026) — quoted, not counted as stock until it lands.
TOPCon N-Type modules deliver 0.5–1.0 percentage points higher efficiency than PERC P-Type, a lower temperature coefficient (typically -0.30%/°C vs -0.35%/°C), and better bifacial gain due to lower recombination. For bankable utility projects and C&I rooftops where BOS and land costs are fixed, higher-wattage TOPCon modules reduce module count, racking, wiring, and labor costs significantly per MWdc installed.
Yes. Sunpro Power has maintained Bloomberg NEF Tier 1 PV Module Manufacturer status for five consecutive years (2022–2026). BNEF Tier 1 is the global standard for bankability accepted by international project finance lenders and tax-equity investors. UL 61730 and IEC 61215/61730 certifications are current.
Yes. Selected TOPCon SKUs assembled at our US manufacturing partner facility in Lyerly, GA qualify for IRA Section 45X Domestic Content treatment, unlocking the 10% ITC bonus adder for eligible projects. Manufacturer attestation, BOM, and Bill of Lading documentation are provided with every Domestic Content shipment.
Pallet configurations vary by SKU — typical TOPCon pallet sizes range from 30 to 36 modules per pallet. Current pallet quantities, panels-per-pallet, and available pallets are shown in real time in the inventory grid above.
Yes. PAN files for PVsyst energy modeling are available for immediate download from our Download Center, along with datasheets, IEC/UL certifications, and product specifications. Custom documentation packages for EPC due diligence can be prepared within 24 hours.
