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.

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.
Request a Quotation
Send the required DC capacity, project location, mounting system, selected inverter platform, delivery destination and target schedule. A2Z EXIMCO can prepare a project-oriented module selection and commercial quotation.
Technical Notice
Technical specifications, model availability, packing configuration and document revisions must be confirmed against the latest official technical document and project quotation before order placement or engineering release.
