What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (465 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 465 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 465 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 | 460 W | 453 W | 444 W | 434 W | 425 W | 416 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |

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 is anchored to the highest published rating in this exact physical and electrical series. Scored model: TWMNH-48HD465 · checked 2026-07-31. Evidence.

Strong evidence coverage
16 of 16 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.
