Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (605 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 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.
| Year | 1 | 5 | 10 | 15 | 20 | 25 |

| Watts | 599 W | 589 W | 577 W | 565 W | 553 W | 541 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |

Market context

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
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.
Record correction. GCL Australian NT10/72GDF 600-605 datasheet and AU warranty Rev. 2024-EN-AU-CEC-VER.1.0 Corrected 2026-08-18: Cell technology tier set to TOPCon tier. The exact-model datasheet already established N-type TOPCon and the scoring field was simply empty, so the record was scoring its own missing-data floor.
