TSEC TS66-CMH-525 H1 525W N-Type TOPCon Monocrystalline Solar Panel
Model TS66-CMH-525 H1 | N-Type TOPCon | 132 Monocrystalline Cells | Monofacial | 1500V System Voltage
Product Overview
The TSEC TS66-CMH-525 H1 525W N-Type TOPCon monocrystalline solar panel is engineered for projects that demand high power density and long-term reliability. This advanced module uses N-type TOPCon cell technology and a 132-cell layout to deliver strong performance in a compact footprint. With a maximum output of 525 Wp and module efficiency of 22.1%, it supports space-constrained residential, commercial, and industrial rooftops. The panel is designed for 1500V systems, allowing flexible string design and reduced balance-of-system costs. Made in Taiwan, it combines robust construction, optimized thermal behavior, and low annual degradation for dependable energy production over decades.
Key Benefits
High power density per module: Deliver up to 525 Wp from a single panel with 22.1% module efficiency, enabling more power on limited roof space.
Advanced N-type TOPCon technology: N-type TOPCon monocrystalline cells offer better temperature behavior, lower degradation, and higher energy yield over the system lifetime.
Enhanced low-light performance: Optimized cell and glass design support stronger output in cloudy, early morning, and late afternoon conditions, improving annual kWh production.
Durable construction for harsh sites: The module uses an anti-salt mist frame, IP68 junction box, and high mechanical load rating, making it suitable for coastal and exposed installations.
Long-term performance guarantees: A 12-year product warranty and 30-year linear power warranty with low annual degradation help protect your investment and forecast returns confidently.
How It Works
This TSEC TS66-CMH-525 H1 solar panel converts sunlight into electricity using high-efficiency N-type TOPCon monocrystalline cells arranged in a 6x22 layout. When light hits the 182 mm cells, it generates direct current, which is then routed through the integrated IP68 junction box and cables to your inverter. The inverter converts the DC power to AC power that can be used onsite or exported to the grid. Optimized temperature coefficients ensure relatively stable power output as the module heats up in real-world operation. The low degradation rate preserves output year after year, supporting predictable long-term energy yields for residential, commercial, and utility-scale systems.
N-Type TOPCon monocrystalline cells: The module uses N-type TOPCon silicon cells that reduce carrier recombination losses and resist light-induced degradation. This structure enables higher efficiency and more stable performance over time than conventional cell types.
Optimized electrical design: At standard test conditions, the panel delivers 525 Wp with a maximum power voltage near 40.25 V and current around 13.05 A. This balance of voltage and current allows flexible string configuration with modern 1500V inverters and helps reduce overall system losses.
Robust module architecture: A coated front glass, low water vapor transmission encapsulant, and durable backsheet protect the cells from moisture and mechanical stress. The IP68 junction box with three bypass diodes manages shading impacts and improves energy harvest under partial shading conditions.
