Year 1 to year 25. Rated 630 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 630 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

16 of 16 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.
