High Power Bifacial Solar Panels
Official Product Series: CW Enerji 655–620Wp M12 132TNBR G2G TOPCon Solar Panels
Technical Code: 132TNB12R
The 132TNB12R series combines N-type TOPCon monocrystalline technology with a 132-cell, 6 × 22 half-cut arrangement and M12-format cells. Eight official power classes span 620–655 Wp, with module efficiency increasing from 22.93% to 24.23%.
Its bifacial double-glass configuration allows the rear surface to contribute energy when the mounting environment provides sufficient reflected irradiance. The official datasheet publishes a 10% rear-side reference matrix for every model, enabling preliminary assessment of increased current and power. Final energy modelling must still reflect actual albedo, mounting height, row geometry and rear-side obstruction.
The 2382 × 1134 × 35 mm module weighs 35.95 kg and supports 1500 V DC system architecture. With Isc reaching 16.44 A under front-side ratings and 18.08 A in the published 10% rear-gain reference, inverter input-current limits, string protection and cable sizing require deliberate review.

Engineering / Selection Notes
- Inverter selection should account for both front-side current and the published rear-gain current. For CWT655-132TNB12R, the sheet lists 16.44 A Isc under front-side ratings and 18.08 A in its 10% reference.
- Calculate maximum series length with the selected Voc, the −0.260%/°C coefficient and the minimum site temperature.
- The 35.95 kg module format requires verified lifting procedures, clamp-zone compatibility and suitable structural or tracker dimensions.
