- Construction
- Bifacial, Dual-glass
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (630 W) applied to the guaranteed floor; modular/format differences aside, this is the same rated-power spec shown above.
Modelled effective output, year by year
Year 1 to year 25. Rated 630 W at STC.
How this is modelled
Modelled from this panel’s own published first-year (1%) and annual (0.4%/yr) degradation figures, compounded against its 630 W rated (STC) output. This is a datasheet-derived estimate, not a field measurement or a warranty guarantee. Actual output also depends on site irradiance, temperature, soiling and system design.
| Year | 1 | 5 | 10 | 15 | 20 | 25 |
|---|---|---|---|---|---|---|
| Watts | 624 W | 614 W | 601 W | 588 W | 576 W | 563 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |

Market context
Global evidencechange in the site menu
Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score uses the 630 W top bin in the current 605-630 W exact series. Scored model: HSM-ND66-GR630 · checked 2026-08-21. Evidence.
Sources & references · checked 2026-09-02
Strong evidence coverage
24 of 24 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
Record revision. TCL exact combined sheet and official brochure rechecked 2026-08-23; fire and degradation are linked and unsupported MBB detail withheld. The undated, unversioned source limitation remains explicit. India existing-catalogue panel ALMM review 2026-09-02: IN overlays recorded against List-I revision 03.08.2026; scores unchanged.

- The exact scored model HSM-ND66-GR630 is not named on ALMM List-I revision 03.08.2026. ALMM is a domestic-content and procurement instrument; absence is not a quality finding and does not change the global score. A manufacturer catalogue is not a substitute for List-I. Existing AU, US, DE or EU warranty terms are not transferred. The catalogue family is HSM-ND66-GR605~630. HSM-ND48 and HSM-BE54 are different identities and are not transferred.

- TCL T Class 66 HSM-ND66-GR610-630 datasheet January 2026 and current resource library, rechecked 2026-08-01 Re-verification 2026-08-19: Verified reliability recorded as "Brand or series independently tested; exact model not covered" under panel rubric v2.13.0, which added a band for brand or series evidence where the exact model is not covered by the third-party record. Re-verification 2026-08-20: Independent energy yield recorded as brand-or-series under panel rubric v2.14.0, which applied to this criterion the same exact-model rule v2.13.0 applied to Verified reliability. Identity and AU evidence closure 2026-08-21: current global family is 605-630 W; exact 630 W is CER-listed, while local stock and warranty remain unestablished.

AU Support Note
- Before
- TCL's current resource library places T Class 66 in its European range and publishes different T5 Pro and C2 families for Australia. Exact Australian sale, approval and warranty remain unproven.
- After
- The exact 630 W bin is regulator-listed in Australia. TCL's Australian resource library does not publish the T Class 66 sale path, current stock or a governing local warranty, so approval is recorded without converting it into an availability claim.
