C2 M

Last verified 2026-10-06.

• 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.
• The July Australian warranty explicitly names the retained HSM-BD66-GR645 to GR670 codes for C&I and large-scale modules. The reviewed residential policies do not list those codes, so residential warranty terms remain unconfirmed and this page remains evidence rather than a score. The datasheet still names IEC 61215 and IEC 61730 without certificate numbers; an exact certification listing is a separate open gate.
• 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.
• For listed C&I and large-scale modules sold after 1 July 2026, the governing Australian policy gives 15-year product and 30-year power coverage. The BC schedule warrants at least 99% of label-rated Minimum Peak Power in year one, annual reduction of 0.35% thereafter and at least 88.85% at year 30. The listed TOPCon schedule is separate and does not apply to this back-contact record.
• Warranty commencement is array interconnection or six months after delivery, whichever comes first; manufacture date substitutes when delivery cannot be verified. Power measurement uses STC (1000 W/m2, AM1.5, 25 C), IEC 60904 and the stated NREL calibration basis, with 3% measurement tolerance and a sweep of at least 200 ms. These conditions do not establish independent energy yield or change the datasheet's power-bin tolerance.
• TCL Zhonghuan Energy Technology (Jiangsu) Co., Ltd. is the warrantor. SunPower Corporation Australia Pty Ltd, described as TCL SunPower in the instrument, administers Australian claims. Claims require prompt contact and requested purchase, delivery/installation, model/serial and defect evidence; returns require prior written authorisation. Full payment and documentation are conditions, and claims must be filed within the applicable term.
• The maker chooses repair, replacement or refund. Reasonable customary transport covers return and delivery to the original maker-delivery location for valid repairs/replacements. Replacement may be refurbished or remanufactured, with compatible mechanical/electrical characteristics and substantially equal or greater power. Refund uses comparable-module spot price multiplied by the remaining fraction of the 15-year product or 30-year power term; repairs and replacements retain only the original remaining term. The C&I policy does not establish unconditional removal, reinstallation or site-labour reimbursement; Australian statutory rights remain preserved.
• Assignment to a subsequent owner requires notice and reasonable ownership documentation; movement from the original installation requires express written approval. Floating systems are excluded unless approved in writing. The policy also names installation/manual violations, exceeded operational ratings, surge, extraordinary events, industrial chemicals and possible direct salt-water contact. EL microcracks alone are not a contractual defect unless they materially affect normal function/structure or warranted power. These exclusions are separate from durability-test results.
• The May 2026 and July 2026 residential policies list other module families, not HSM-BD66-GR. The July residential policy's 25-year term and reasonable removal/reinstallation remedy cannot be assigned to C2 M. Warranty-only 635 W and 640 W codes do not expand this record's 645-670 W technical range, and the manufacturer's wider marketing warranty headline is not a substitute for the exact schedule.
• Warranty documents and their current resource links were reviewed on 6 October 2026. This review does not refresh the technical datasheet, confirm an on-sale date or inventory, establish an exact certification/approval, or resolve residential eligibility. The page remains unscored.

• TCL Solar AU datasheet, C2 M 645-670W (version TCL-HSM-2026-A-EN)https://pub-72985f516cf4462ebe2c3d69275b4a1e.r2.dev/datasheets/emea/au/AU_TCL%20Solar_C2%20M_Datasheet_645-670W.pdf

  Prints the C2 M name, the code HSM-BD66-GR645-670, the TBC back contact bifacial double-glass build, the 645 W to 670 W bins, the listed IEC standards and the legal manufacturer.

• TCL Solar Warranty for C&I and Large Scale PV Modules, Australia, July 2026https://pub-72985f516cf4462ebe2c3d69275b4a1e.r2.dev/warranties/emea/au/AU_TCL%20Solar_T5%20Pro%20M_C2%20M_Warranty_CI-UPP.pdf

  Shows an Australian C&I and large-scale warranty effective 1 July 2026 that lists back contact codes HSM-BD66-GR635 to GR670 alongside TOPCon HSM-ND66 codes.

• TCL Solar resources page (back contact documents)https://www.tclsolar.com/resources?product=6a6344d087cead4360bc1233

  Confirms tclsolar.com links to both the AU C2 M datasheet and the AU T5 Pro M C2 M warranty at the document host used above.

• TCL Solar current technical resourceshttps://www.tclsolar.com/resources

  Observed public catalogue links the May ANZ policies and July AU residential/C&I instruments on the same maker-linked document host. Catalogue labels do not broaden exact model schedules.

• TCL Australian residential warranty, effective 26 May 2026: other-model boundaryhttps://pub-72985f516cf4462ebe2c3d69275b4a1e.r2.dev/warranties/row/AU_TCLSolar_module_warranty_May26_RES.pdf

  Physical pages 2-3 restrict coverage to the printed table; no HSM-BD66-GR codes are listed. Its 25-year product term does not transfer.

• TCL Australian residential T5 Pro/C2 warranty, effective 1 July 2026: other-model boundaryhttps://pub-72985f516cf4462ebe2c3d69275b4a1e.r2.dev/warranties/emea/au/AU_TCL%20Solar_T5%20Pro_C2_Warranty.pdf

  Physical pages 2-4 give the model table and reasonable removal/reinstallation remedy for listed residential models, which do not include HSM-BD66-GR. That remedy and 25-year term are not assigned to C2 M.
