- Construction
- Mono-glass
Performance guarantee: 25-year linear output
Wattage figure based on the sourced rated power (440 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 440 W at STC.
How this is modelled
Modelled from this panel’s own published first-year (1.5%) and annual (0.33%/yr) degradation figures, compounded against its 440 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 | 433 W | 428 W | 420 W | 413 W | 406 W | 399 W |
| % of rated | 98.5% | 97.2% | 95.5% | 93.9% | 92.2% | 90.6% |

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 published US series. Scored model: Q.TRON BLK M-G2+ 440 · checked 2026-07-16. Evidence.

Strong evidence coverage
21 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 correction. Corrected 2026-08-19: the LeTID resistance value is withdrawn as unverifiable - the cited datasheet is neither archived nor reachable. No score changes: the field is unscored. 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.
