The SP635-144M is the flagship of our N-type TOPCon module series, built with 182mm 18BB half-cut monocrystalline cells in a 144-cell layout. TOPCon (Tunnel Oxide Passivated Contact) technology pushes cell efficiency to 25% or higher, delivering roughly 3-5% more real-world energy yield than conventional PERC modules of the same size, especially in high-temperature and low-irradiance conditions.
With power classes from 410W to 635W, this series serves residential rooftops, commercial installations and utility projects from a single platform, simplifying procurement and spare-part management for our distributors.
Key Features
- High module efficiency: up to 22.8% from N-type TOPCon cells rated up to 25% cell efficiency.
- Low temperature coefficient: -0.30%/K limits power loss on hot rooftops and in tropical climates.
- Half-cut 18BB design: 144 half-cut multi-busbar cells reduce internal resistance and improve shade tolerance.
- Heavy-duty construction: anodized aluminium frame, 3.2mm tempered glass and IP68 junction box, certified for 55m/s wind and 1.5kN/m² snow loads.
- Bankable warranty: 12-year product warranty with linear performance guaranteed at 87.4% of rated power after 25 years.
- One platform, many sizes: power classes from 410W to 635W share the same mechanical platform.
Typical Applications
Residential rooftops, commercial and industrial roofs, and utility-scale ground mounts – particularly where high temperatures or low-light conditions make N-type yield advantages count.
Common Pain Points We Solve
- Rigid MOQs: we accept container-mixed orders – panels can share a container with inverters, batteries and racking, so one shipment covers a whole project.
- Unstable supply: our 5GW annual capacity and 45,000m² Foshan factory keep lead times short and repeatable across 130+ export countries.
- Thin distributor margins: factory-direct pricing removes trading-company markups and protects your resale margin.
- Brand building: neutral packing and OEM labelling are available, so distributors can grow their own brand on our production line.
