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 (520 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 520 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 520 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 | 515 W | 506 W | 496 W | 486 W | 475 W | 465 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |

Strong evidence coverage
14 of 14 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.
