Model TS66-CMH-555 H1 | N-Type TOPCon | 132 Monocrystalline Cells | Monofacial | 1500V System Voltage
The TSEC TS66-CMH-555 H1 555W N-Type TOPCon Monocrystalline Solar Panel delivers high efficiency in a compact footprint. Designed around advanced TOPCon cell technology, this module converts more sunlight into usable power with a panel efficiency up to 23.4%. Its 555W output makes it ideal for commercial roofs, industrial arrays, and high performance ground mount systems. The module carries a 12 year product warranty and a 30 year linear power warranty, providing long term investment protection for your project. Power output is guaranteed at 91.4% after 20 years and 87.4% after 30 years, supporting stable long term yields. With a maximum system voltage of 1500V, this TSEC solar panel integrates smoothly into modern large scale strings, helping reduce system balance of plant costs. The module is engineered and manufactured in Taiwan with strict quality standards, robust mechanical strength, and reliable performance in diverse climates.
High power density: Generate more energy per module with a maximum output of 555W and up to 23.4% efficiency, enabling smaller arrays for the same target production.
Advanced N-Type TOPCon cells: Monocrystalline TOPCon cells deliver better temperature performance, reduced degradation, and strong low light response compared to conventional P-type modules.
Proven long term reliability: A 12 year product warranty and 30 year linear power warranty support long term asset planning and bankability for commercial and utility projects.
Robust mechanical design: The module is tested to high mechanical load levels and uses an anti salt mist frame and IP68 junction box for reliable outdoor operation in challenging environments.
Optimized for modern systems: A 1500V system rating, 25A series fuse rating, and EVO 2 compatible connectors support efficient string design and simple integration with leading inverters.
This TSEC TS66-CMH-555 H1 solar panel converts sunlight into direct current electricity through high efficiency N-Type TOPCon monocrystalline cells. Each of the 132 cells is wired together to form a 6x22 module layout that optimizes voltage and current for 1500V systems. When sunlight hits the silicon cells, photons excite electrons and create an electric current that flows through the panel’s busbars and out through the EVO 2 compatible connectors. The resulting DC power is then routed to an inverter, which converts it into AC power suitable for on site consumption or grid export. The module’s low temperature coefficient values help maintain higher power output as cell temperatures rise during sunny days. Under low irradiance conditions, the advanced cell structure and anti reflective coated glass enhance light capture, supporting more stable production from dawn to dusk. An integrated IP68 junction box with three bypass diodes helps protect performance if part of the module is shaded, keeping energy production as high as possible within the string.
N-Type TOPCon cell operation: N-Type TOPCon monocrystalline cells use a passivated contact structure that reduces electron recombination, allowing more charge carriers to reach the busbars. This design supports higher efficiency, lower degradation, and better performance at elevated temperatures than many conventional cell types.
Module layout and electrical output: The 6x22 cell arrangement is configured to deliver a maximum power voltage of about 41.04V and a maximum power current around 13.53A under standard test conditions. This balance of voltage and current delivers 555W output while keeping resistive losses lower within strings and system wiring.
Protection and durability in operation: Front PV coated glass, a durable backsheet, and an anti salt mist frame protect the cells against moisture, dust, and corrosion over decades of use. The IP68 junction box and three bypass diodes support stable output in partial shading scenarios, helping to reduce hot spot risk and improve long term reliability.
