Specifications
Product Description
The Pack of 10 Trina 590W Bifacial Solar Panels NEG18C.20 Vertex S+ brings together ten next-generation modules with N-type i-TOPCon technology, 144 half-cell design, and dual-glass encapsulation of 2.0 mm + 2.0 mm. With a total power of 5.90 kWp and an efficiency of 22.8%, this pack is designed to maximize annual production in advanced residential projects and, above all, on commercial and industrial rooftops. The bifaciality of 80% (±5%) allows the use of reflected light from the surface, achieving a measured rear gain that can reach up to 25% depending on the albedo, all with the robustness, reliability, and guarantees characteristic of the Vertex S+ series.
Main Features
- Power per module: 590 W (tolerance 0~+5 W); efficiency of 22.8%.
- Tempered dual-glass 2.0 mm + 2.0 mm, 30 mm frame, and IP68 junction box.
- 144 N-type i-TOPCon half-cells with lower degradation: 1% in the first year and 0.4% annually up to 30 years.
- Electrical parameters (STC) per module: Vmp ≈ 44.6 V, Imp ≈ 13.23 A; Voc ≈ 52.6 V, Isc ≈ 13.87 A.
- Max. system 1500 V DC, series fuse 30 A; coefficients: Pmax −0.29%/°C, Voc −0.24%/°C, Isc +0.04%/°C; NOCT 43 ± 2 °C.
- Dimensions/weight (module): 2278 × 1134 × 30 mm and 31.9 kg; MC4-EVO2 / TS4 Plus connector, PV cable 4 mm².
Advantages or Benefits
- More kWh per m²: high efficiency and bifaciality with real rear-gain on light surfaces (white membranes, light gravel, carports).
- Optimized installed cost: 5.90 kWp with only 10 modules; less structure, fewer fixings, and less installation time.
- Superior durability of dual-glass: lower permeability and risk of microcracks, ideal for demanding climates (marine, dust, humidity).
- Stable performance in heat thanks to the low thermal power coefficient (−0.29%/°C).
- Long-term warranties (product and power) that increase the residual value of the system.
Purpose or Applications
Optimal pack for commercial and industrial rooftops, logistics warehouses, retail, and agro-industry; also suitable for premium residential, pergolas, and carports. The active rear side allows the use of high albedo to reduce LCOE and improve return on investment.
