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 (0.35%/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.

Strong evidence coverage
22 of 28 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.
