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.

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 610-630 W exact series. Scored model: HSM-ND66-GR630 · checked 2026-08-01. Evidence.

Strong evidence coverage

22 of 25 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 correction. 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.
