Utility Scale Solar Panels
The 132TNB12 family is a high-output module platform developed around N-type TOPCon monocrystalline cells, an 18-busbar layout and a 132-cell half-cut configuration. Its 715–755 Wp power range enables project designers to place substantial DC capacity within each module position, supporting higher installed power density in land-constrained or balance-of-system-sensitive projects.
Module efficiency increases from 23.02% to 24.31% across the official power classes. The series combines bifacial energy generation with a glass-to-glass structure, self-cleaning anti-reflection glass, positive power tolerance and operation in 1500 V DC systems. The electrical window extends to 50.00 V Voc and 18.99 A Isc at the highest power class, making current capacity and cold-condition string voltage important inverter-selection inputs.
The 2384 × 1303 mm format is particularly relevant to large ground-mounted arrays where fewer module units per megawatt can simplify repetitive installation work. Its 34.5 kg weight and large surface area require coordinated handling, structural and tracker compatibility reviews. Rear-side contribution should be assessed from project-specific albedo, row spacing, ground clearance and shading conditions.

Published Rear-Side Reference Data
The official sheet labels this auxiliary table “715W Front Power Referenced.” The figures below are transcribed exactly as published.

|---|---|---|---|---|---|
| Peak Power, Pmax | 766.50 W | 803 W | 839.50 W | 876 W | 912.50 W |

The published Pmax values do not arithmetically align with the stated 715 W reference label. This auxiliary table should therefore be confirmed against the current document revision before engineering release.
Engineering / Selection Notes
- Determine maximum string length from the selected model’s Voc, the −0.260%/°C Voc coefficient and the project’s minimum design temperature.
- Confirm inverter MPPT and short-circuit input limits against currents up to 18.02 A Imp and 18.99 A Isc before applying any rear-side contribution.
- Verify tracker dimensions, mounting zones, wind design, lifting method and installation manpower for the 2384 × 1303 mm, 34.5 kg module format.
