Year 1 to year 25. Rated 605 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 605 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.

Market context

Global evidencechange in the site menu

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The score uses the highest exact current power bin in the retained market source. Scored model: GCL-NT10/72GDF-605 · checked 2026-08-06. Evidence.

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.
