N-Type TOPCon Bifacial Dual Glass PV Module
Maximizing energy yield for commercial, industrial, and ground-mount projects requires high-density PV architecture. The HTM490~510DMH6-54NT series combines N-Type TOPCon technology, 210R rectangular mono cells, and a dual-glass bifacial configuration to deliver up to 22.93% module efficiency and up to 638W total power output with backside gain.
Designed for long-term project viability, this module significantly lowers the Levelized Cost of Electricity (LCOE) through reduced degradation, superior low-light performance, and robust environmental resistance.

for C&I Rooftop & Ground-Mounted PV Projects
In modern commercial installations, balancing roof load limits, maximizing limited surface area, and minimizing Balance of System (BOS) costs are critical to achieving a favorable return on investment.
Optimized Dimensions for Easy Handling: Measuring 1961*1134*30mm and weighing 27 kg, these modules fit the ergonomic limits for two-person manual handling on commercial roofs. This structural footprint speeds up installation timelines and lowers labor costs compared to bulkier utility-scale panels.
Higher Yield on Reflective Commercial Surfaces: Most commercial roofs feature concrete, TPO membrane, or light-colored coatings. The bifacial dual-glass construction captures reflected light from these surfaces, delivering an extra 5% to 15% power gain. This boosts real-world operational output up to 536W–587W per module without taking up additional roof space.
FAQ
Q: What is the expected rearside power gain from the bifacial design?
A: The module delivers an additional 5% to 25% power generation depending on surface reflectivity (albedo).
Q: What is the mechanical load rating for wind and snow?
A: The module is built with an anodized aluminum frame and 2.0mm dual reinforced glass, certified to withstand heavy snow loads up to 5400 Pa on the front side and wind loads up to 2400 Pa on the rear side.
Q: Can I order custom cable lengths for specific system designs?
A: Standard stock configurations come with 4.0mm2 cables (positive 200 mm / negative 250 mm). Custom cable lengths and specific connector types can be provided for container-load OEM/project orders.
Q: What international certifications does this product hold for customs clearance?
A: The series is certified under IEC 61215 and IEC 61730 safety/performance standards. Our manufacturing facilities comply with ISO 9001 (Quality), ISO 14001 (Environment), ISO 45001 (Safety), and IEC 62941 (PV Manufacturing Quality).
Q: What is the Light-Induced Degradation (LID) rate?
A: N-Type TOPCon cells use boron-oxide-free composite materials, virtually eliminating Light-Induced Degradation (LID) and Light- and Elevated Temperature-Induced Degradation (LeTID). This ensures stable real-world output right from initial commissioning.
