N-Type TOPCon Solar Panels for Utility-Scale and Commercial Projects

TOPCon technology is not limited to specific wattages. We offer PP TOPCon solar panels from 585W to 720W. Other major brands also use TOPCon across a wide range of power ratings, so wattage alone does not determine whether a panel can use this technology. Tell us your required wattage and quantity, and we can confirm suitable PP or branded module options for your order.

TOPCon solar panel manufacturers include Tier 1 solar panel brands such as LONGi, JA Solar, Canadian Solar, Trina Solar, Risen, and Tongwei. We work closely with these brands and supply their solar modules alongside our own PP panels. We also support OEM/ODM orders. You can discuss your preferred brand, model, or customization requirements with us when requesting a quotation.

Our 690–720W TOPCon series achieves module efficiencies of 22.21%–23.18% under standard test conditions. The 720W model has the highest efficiency within this series, at 23.18%. We provide the efficiency rating for each power option in the product datasheet, so you can compare models using the same test conditions. These figures describe complete modules, rather than individual solar cells.

TOPCon panels generally offer higher module efficiency than conventional PERC panels, which can help you install more generating capacity in the same area. Whether they offer better value depends on the specific models and project costs. We recommend comparing efficiency, temperature coefficient, degradation warranty, and price together. A lower-priced PERC module can still be worth considering when installation space is plentiful.

The main difference is the cell structure: TOPCon uses a tunnel oxide and silicon contact layer, while HJT combines crystalline silicon with thin amorphous silicon layers. Both technologies can use N-type silicon and support bifacial modules. We can help you compare their module efficiency, temperature coefficient, and price. The better choice depends on the specific products and the operating conditions of your project.

Yes. Our OEM/ODM options include customized high-transmission glass, TOPCon cells, anodized aluminum frames, IP68 junction boxes, MC4-compatible solar connectors, and custom OEM labels. For other module orders, we also offer HJT or PERC cell options. Tell us your required configuration, branding, and order quantity. We will confirm the component specifications, minimum order quantity, lead time, and price with you before production.

Allow the ventilation clearance specified in the module and mounting-system manuals, and keep airflow paths beneath the panels unobstructed. For project design, account for the mounting arrangement, roof conditions, and local operating temperatures. We provide module installation guidance and power temperature coefficients to support your technical review. In hot climates, compare expected temperature-related output losses when selecting modules for bulk procurement.

For bulk orders, match the manufacturer and model on the module labels with the quotation, datasheet, warranty, and applicable certification documents. Check serial-number traceability and warranty coverage for your destination market. We can review the product documentation with you before order confirmation. At delivery, check the module identification and packing records against your purchase order, and retain these documents for after-sales support.

Yes. TOPCon modules suit residential installation projects when their dimensions, weight, and electrical ratings match the system design. For bulk procurement across multiple rooftops, consider the typical roof layouts, mounting requirements, and inverter specifications your projects use. We can help you compare suitable module options and provide technical information for your procurement review. Higher efficiency can be useful where roof space is limited.
