Specifications
Product Description
The Trina 505W Bifacial Solar Panel NEG18RC.27 Vertex S+ is a next-generation module that combines N-type i-TOPCon cells, a 108 half-cell format, and dual-glass encapsulation to deliver real power, extreme reliability, and an extended service life. With a nominal power of 505 W and an efficiency of 22.7%, this bifacial panel increases annual output thanks to the gain from its rear side (bifaciality 80% ±5%), especially on roofs with high albedo (white membranes, light gravel, or carports). Designed for 1500 V systems, it integrates with most modern inverters and stands out for its mechanical robustness, excellent thermal response, and extended warranties.
Main Features
- 505 W of power with 0~+5 W tolerance and 22.7% efficiency for maximum power density per m².
- 1.6 mm + 1.6 mm bifacial dual glass that improves sealing and reduces the risk of microcracks.
- 108 N-type i-TOPCon half-cells (210 platform) with lower degradation: 1% in the first year and 0.4% annually up to 30 years.
- Typical electrical parameters (STC) per module: Vmp 33.5 V / Imp 15.09 A; Voc 40.3 V / Isc 15.89 A.
- Maximum system 1500 V DC, series fuse 30 A; IP68 junction box and MC4-EVO2/TS4 Plus connectors.
- Mechanical loads 5400 Pa (positive) / 2400 Pa (negative) and excellent thermal performance (−0.29%/°C at Pmax).
Advantages or Benefits
- More kWh per surface area: the combination of high efficiency and bifaciality provides typical gains of 5–10% depending on albedo.
- Optimized installed cost: fewer modules and structure needed to reach the same field power.
- Superior reliability: dual-glass encapsulation ensures lower permeability to moisture and chemical agents (salt mist, ammonia).
- Stable performance in warm climates thanks to a very low power coefficient and N-type technology.
- Wide compatibility with current inverters and microinverters, enabling flexible designs for residential and C&I applications.
Purpose or Applications
Ideal for premium residential self-consumption, SMEs, and commercial or industrial rooftops, carports, and solar pergolas. Its active rear side takes advantage of reflective surfaces to increase annual output, making it an ideal solution when seeking to reduce LCOE and maximize return on investment.
