TSEC TS66-CMH-550 H2 550W TOPCon Bifacial Solar Panel
Model TS66-CMH-550 H2 | TOPCon | 132 Cells | Bifacial | 1500V System Voltage
Product Overview
The TSEC TS66-CMH-550 H2 is a high-efficiency bifacial solar panel built for strong energy output and reliable long-term performance. It uses TOPCon monocrystalline cell technology to support excellent conversion efficiency and stable operation across demanding commercial and utility projects. With a rated power of 550 Wp and panel efficiency of 23.2%, this module is designed to deliver more usable energy from a compact footprint. The bifacial design can capture additional rear-side gain when installed in suitable conditions. A 12-year product warranty and 30-year linear power warranty add long-term confidence for project planning.
Key Benefits
High Power Output: The module delivers 550 Wp at STC for strong system-level energy production.
Excellent Efficiency: A 23.2% efficiency rating helps maximize generation in limited roof or ground space.
Bifacial Energy Gain: Rear-side power capture can increase yield when the installation environment reflects light well.
Durable Construction: The IP68 junction box, anti-salt mist frame, and 5400 Pa load rating support rugged deployment.
Long Service Life: The power warranty supports 91.4% after 20 years and 87.4% after 30 years.
How It Works
This solar module converts sunlight into electricity through TOPCon monocrystalline cells arranged in a 132-cell layout. The front side produces the main electrical output, while the bifacial design can also capture reflected light from the rear. That additional rear-side contribution can improve total energy yield in elevated, reflective, or well-optimized installations. The electrical characteristics are tuned for stable string design, with a 1500V maximum system voltage and 30A fuse rating supporting modern solar arrays. Its low temperature coefficients help maintain performance as module temperatures rise during operation.
TOPCon Cell Conversion: Sunlight is absorbed by the monocrystalline TOPCon cells and converted into direct current electricity. The cell technology supports high efficiency and steady output.
Bifacial Rear-Side Gain: Light reflected from the installation surface reaches the rear side of the module. This can add extra generation depending on tilt, height, and ground reflectivity.
System Integration: The module works within standard string architectures and supports a 1500V system design. The IP68 junction box and EVO-2 compatible connector simplify installation and protection.
