High-Efficiency N-type Bifacial Solution
For project developers and commercial solar integrators looking to maximize energy yield, our TopCon solar module 615W delivers a proven balance of high power density and long-term reliability. Built with advanced N-type technology and a durable double-glass structure, these modules are engineered to perform in the demanding conditions often found in commercial solar projects across Southeast Asia and Africa.
By reducing the Levelized Cost of Energy (LCOE), this module serves as a cornerstone for utility-scale plants and large-scale industrial microgrids.
Key Advantages for Your Solar Projects
- Advanced N-type Technology: Unlike traditional P-type modules, our TopCon (Tunnel Oxide Passivated Contact) cells significantly reduce Light Induced Degradation (LID), ensuring your system maintains higher output over its entire 25+ year lifespan.
- Superior Temperature Performance: With an industry-leading temperature coefficient of -0.290%/°C, this module thrives in high-heat environments. It produces more power during peak sun hours in tropical climates, where standard modules often experience significant efficiency drops.
- Bifacial Energy Gain: The double glass design allows for rear-side power generation. By capturing reflected light (albedo) from the ground, you can achieve a total energy yield increase of up to 25%, depending on the installation environment.
- Rugged Durability: Featuring 2.0mm heat-strengthened glass on both sides, this module offers excellent fire resistance and superior protection against sandstorms, heavy humidity, and high-wind loads.

Long-Term Asset Protection
For project developers and investors, hardware cost is only half the story; long-term yield is where the actual project value lies. Our N-type bifacial modules are built to deliver consistent energy output, backed by a robust 30-year linear performance warranty that gives you genuine peace of mind throughout the entire project lifecycle.
We guarantee a minimal first-year degradation of just 1%, followed by a strictly controlled annual degradation rate of 0.4%. In practical terms, this outperforms most standard modules currently on the market, ensuring you retain significantly higher power output at the 30-year mark. This sustained performance directly lowers the Levelized Cost of Energy (LCOE), turning your installation into a more profitable, long-term asset.

FAQ
Q: What is the actual bifacial gain I can expect?
A: Bifacial gain typically ranges from 5% to 25%, depending on the ground albedo (reflectivity) and installation height. Light-colored surfaces like gravel or sand will maximize the rear-side energy harvest.
Q: Are these modules certified for projects requiring bankability?
A: Absolutely. Our modules carry full IEC 61215/61730 and UL 61215/61730 certifications, meeting the strict quality standards required by international financial institutions and insurance providers.
Q: Can you customize the cable length for my specific project layout?
A: Yes. We offer customized cable lengths to optimize string design and reduce the need for additional extension cables, which helps lower overall Balance of System (BOS) costs.
Q: Do you provide support for project system design?
A: Yes. We offer technical documentation, including PVsyst simulation files and installation manuals, to help EPCs and system designers optimize the layout for maximum yield.
Q: What measures are in place to prevent micro-cracking during installation?
A: Our dual-glass architecture is inherently more resistant to micro-cracking than single-glass modules. Furthermore, the heat-strengthened glass provides superior mechanical load capacity against wind and snow.
