Trina Solar 620 620W N-Type TOPCon Monocrystalline Solar Panel
Model 620 | N-Type TOPCon | 132 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Trina Solar 620W panel is built for high-output commercial and utility-scale installations. This monocrystalline module uses N-type TOPCon technology to support strong energy production and long-term reliability. Its bifacial dual-glass design helps capture more light from both sides, which can improve total system yield in suitable conditions. With a module efficiency of up to 23%, it is designed to deliver more power in limited roof or ground space. The panel also features a 12-year product warranty and a 30-year power warranty, giving buyers confidence in long-term performance. Its low degradation rate and wide operating temperature range make it a practical choice for demanding solar projects.
Key Benefits
High Power Output: The module delivers up to 620 Wp for strong performance in large-scale solar arrays.
High Module Efficiency: Up to 23% efficiency helps maximize energy generation in compact installation areas.
Bifacial Dual-Glass Design: Rear-side energy capture can improve total output in reflective environments.
Low Degradation: The expected degradation rate is only 0.42%, supporting stable long-term performance.
Strong Reliability: Anti-reflection glass, an IP68 junction box, and high weather resistance improve durability.
Lower System Costs: High string power can help reduce balance-of-system costs and improve project value.
How It Works
This solar panel converts sunlight into electricity through N-type TOPCon monocrystalline cells. The half-cut structure helps reduce resistance losses and supports better performance under partial shading. The bifacial format allows the rear side to generate additional energy when light is reflected from the installation surface. Dual-glass construction increases strength and protects the module during long-term outdoor exposure. The panel is engineered for stable performance across changing temperatures, while low temperature coefficients help limit output loss in heat. Together, these design features support efficient power generation, dependable operation, and strong lifetime value for commercial solar projects.
TOPCon Cell Conversion: Sunlight is converted by N-type TOPCon cells with improved efficiency. The advanced cell structure supports higher output and better long-term stability.
Bifacial Energy Capture: The rear side can collect reflected light from the installation surface. This can increase total energy yield in suitable site conditions.
Half-Cell and Dual-Glass Design: Half-cut technology helps reduce electrical losses and hotspot risk. The dual-glass format adds durability for harsh weather exposure.
