- TCL Solar describes the C2 M as an N-type back contact (TBC) bifacial double-glass panel with 132 cells and no busbars on the front side.
- Legal manufacturer as printed: TCL Zhonghuan Energy Technology (Jiangsu) Co., Ltd.
- TCL Solar publishes an Australian datasheet and an Australian warranty effective 1 July 2026 that lists this code family, but neither document states an on-sale date.
- It cannot be scored yet because the datasheet names IEC 61215 and IEC 61730 without certificate numbers, and the Australian warranty listing this code is written for C&I and large-scale modules, so residential terms are not confirmed.
- The 670 W and 24.8% headline is the top bin only; the datasheet rates bins from 645 W (23.9%) upward, while the warranty also lists 635 W and 640 W codes the datasheet does not.
- The Australian warranty lists TCL TOPCon modules under separate HSM-ND66 codes, so this page is not joined to any TOPCon or other scored record.
