TCL 620W N-Type Bifacial Solar Panel

Advanced N-Type TOPCon Technology

The TCL 620W Bifacial Solar Panel is a high-performance solar module developed for residential, commercial, industrial, and utility-scale solar installations. It uses advanced N-Type TOPCon cell technology to deliver a rated maximum power output of 620 watts with module efficiency of up to 23.0%.

The panel belongs to TCL Solar’s G12R-66P series and carries the model number HSM-ND66-GR620. Its high efficiency, low power degradation, and reliable performance under varying environmental conditions make it suitable for long-term solar energy projects.

Bifacial Double-Glass Design

The TCL 620W solar panel features a bifacial double-glass construction that can generate electricity from both the front and rear sides. While the front side receives direct sunlight, the rear side captures reflected light from the ground or surrounding surfaces.

According to the manufacturer’s data:

• Output with 5% bifacial gain: approximately 651W
• Output with 10% bifacial gain: approximately 682W
• Maximum power under BNPI conditions: 685W

Actual rear-side energy gain depends on the mounting structure, installation height, tilt angle, and reflectivity of the surface beneath the module.

High Module Efficiency

With module efficiency of up to 23.0%, the TCL 620W N-Type Solar Panel produces high power from the available installation area. This makes it particularly useful for projects where maximum energy generation is required from limited rooftop or ground space.

Its 0 to +3% positive power tolerance means the module is designed to deliver at least its rated power and may provide slightly higher output under standard testing conditions.

Reliable Performance in High Temperatures

The panel has a -0.28%/°C temperature coefficient of maximum power, helping it maintain stable energy production as cell temperatures rise.

Its operating temperature range of -40°C to +85°C allows the module to function reliably in a wide range of environmental and climatic conditions.

Strong and Durable Construction

The TCL 620W Bifacial Solar Panel uses:

• 2.0mm heat-strengthened front glass
• Anti-reflective coating on the front glass
• 2.0mm heat-strengthened rear glass
• Anodized aluminium alloy frame
• IP68-rated junction box with three diodes

The double-glass structure improves resistance to moisture, harsh environmental conditions, and long-term physical stress.

High Mechanical Load Capacity

The module is engineered to withstand substantial mechanical pressure, supporting:

• 5400 Pa front-side static load
• 2400 Pa rear-side static load

This makes it suitable for rooftop, industrial, ground-mounted, and large-scale solar projects where dependable structural performance is required.

1500V DC System Compatibility

The TCL 620W module supports a maximum system voltage of 1500V DC and a maximum series fuse rating of 30A. Its low-voltage design can help optimize balance-of-system costs in properly designed commercial and utility-scale installations.

Long-Term Performance Warranty

The TCL G12R-66P module series is supplied with:

• 15-year product warranty
• 30-year linear performance warranty
• Approximately 99% initial-year performance
• At least 87.4% output after 30 years

Warranty coverage remains subject to TCL Solar’s official warranty terms and conditions.

Ideal Applications

The TCL 620W N-Type Bifacial Solar Panel is suitable for:

• Residential on-grid solar systems
• Residential hybrid solar systems
• Commercial rooftop installations
• Industrial solar projects
• Ground-mounted solar systems
• Utility-scale solar power plants
