Trina Solar panel 725W Bifacial Dual-Glass Solar Panel TSM-725NEG21C.20

Trina Solar Vertex N 725W N-Type Bifacial Solar Panel

The Trina Solar Vertex N 725W is a high-output photovoltaic module engineered for large commercial rooftops, industrial facilities, ground-mounted systems, and utility-scale solar power plants.

Built on Trina Solar’s 210mm technology platform, the module combines advanced N-type i-TOPCon cells, bifacial energy generation, half-cut cell technology, and a durable dual-glass structure. This design provides high module efficiency, strong energy yield, reduced temperature-related losses, and reliable long-term performance.

High 725W Power Output

The 725W model provides high power density, helping reduce the number of modules, mounting components, electrical connections, and installation space required for large solar projects.

Electrical Performance at STC

• Rated maximum power: 725W
• Module efficiency: 23.3%
• Maximum power voltage: 41.5V
• Maximum power current: 17.47A
• Open-circuit voltage: 49.6V
• Short-circuit current: 18.54A
• Positive power tolerance: 0 to +5W

The high output and efficiency make the module particularly suitable for projects where maximum generation per installed panel is important.

Advanced N-Type i-TOPCon Technology

The Vertex N module uses patented i-TOPCon technology, designed to improve conversion efficiency and long-term energy production.

The technology incorporates improvements such as reduced contact resistance, enhanced rear reflection, and optimised cell-edge quality. These features help deliver reliable performance under different operating and environmental conditions.

Main Performance Benefits

• High conversion efficiency
• Excellent low-irradiance response
• Reduced temperature-related power losses
• Lower degradation characteristics
• Strong long-term energy production
• Improved reliability through reduced micro-crack risk
• Reduced hot-spot risk through half-cut cell technology

Bifacial Rear-Side Power Generation

The bifacial design allows the module to generate electricity from both surfaces. Direct sunlight is converted on the front side, while reflected light reaching the rear side provides additional power.

Depending on ground reflectivity, mounting height, panel angle, row spacing, and rear-side shading, the module can provide approximately 10% to 20% additional rear-side energy gain.

The datasheet lists a power bifaciality of approximately 80% ±7%. Under the stated bifacial test condition, the 725W model can reach a total equivalent output of approximately 801W.

Actual bifacial gain will depend on the installation environment and system design.

Durable Dual-Glass Construction

The module uses 2.0mm heat-strengthened glass on both the front and rear surfaces, providing enhanced protection for the solar cells.

Its dual-glass design offers improved resistance against:

• Moisture and humidity
• Temperature changes
• Mechanical stress
• Environmental exposure
• Long-term outdoor operation
• Potential micro-cracking and degradation

The module also includes an anodised aluminium-alloy frame, an IP68-rated junction box, and Stäubli MC4-EVO2 connectors.

Excellent Performance in Hot Conditions

The module has a maximum-power temperature coefficient of -0.29% per °C. This helps reduce the loss of output power as module temperature rises.

It is therefore suitable for hot and sunny environments where solar panels frequently operate above standard laboratory temperatures.
