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 (475 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 475 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 475 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 | 470 W | 463 W | 453 W | 444 W | 434 W | 425 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |

Strong evidence coverage
20 of 20 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. ASTRO N7s 2.0 CHSM48RN(DG)/F-BH AU 20250916 V2.1, 455-475 W LeTID re-verified 2026-08-19 for rubric v2.12.0: scored under the returned criterion on the evidence recorded in its provenance.
