Specifications
Product Description
The Trina 620W Bifacial Solar Panel NEG19RC.20 Vertex S+ is a high-power module designed to maximize annual output in modern installations. It combines next-generation N-type i-TOPCon cells with dual-glass encapsulation (2.0+2.0 mm), reaching 620 W nominal power and an efficiency of 23%. Its active rear side, with bifaciality ≈80% (±5%), utilizes reflected light from high-albedo surfaces to generate additional kWh, while the double glass construction provides outstanding robustness against humidity, salt mist, or ammonia. Prepared for 1500 V systems, this model integrates seamlessly into premium residential projects and, especially, into commercial and industrial self-consumption where LCOE and reliability are critical.
Main Features
- Power per module: 620 W (tolerance 0~+5 W) with 23% efficiency.
- Double glass 2.0+2.0 mm and IP68 junction box for maximum sealing and service life.
- 132 half-cut N-type i-TOPCon cells with low degradation: 1% in the first year and 0.4% annually up to 30 years.
- Typical electrical parameters (STC): Vmp ≈ 49 V, Imp ≈ 12.8 A; Voc ≈ 49–50 V, Isc ≈ 13 A.
- Maximum system 1500 V DC, 35 A series fuse; power coefficient −0.29%/°C.
- Format and weight: 2382 × 1134 × 30 mm, 33.7 kg; MC4-EVO2 / TS4 Plus connectors and 4 mm² PV cable.
Advantages or Benefits
- More energy per surface area thanks to high efficiency and bifaciality (typical rear-gain 5–30% depending on albedo).
- Reduction in structure and labor costs by providing more W per module.
- Superior reliability of dual-glass: lower permeability and better resistance to microcracks and corrosive agents.
- Stable performance in warm climates due to its low thermal power coefficient.
- Wide compatibility with modern 1500 V inverters and microinverters for flexible designs in C&I and residential applications.
Purpose or Applications
Ideal for commercial and industrial rooftops, logistics warehouses, retail, agribusiness, and carports; also for high-demand residential use. Delivers its best performance on reflective surfaces such as white membranes, light gravel, or high-albedo pavements, where the rear side generates additional energy that accelerates return on investment.
