Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (645 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 645 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 645 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 |

Strong evidence coverage
22 of 26 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. LeTID re-verified 2026-08-19 for rubric v2.12.0: scored under the returned criterion on the evidence recorded in its provenance. 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.
