Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (540 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 540 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 540 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 | 535 W | 526 W | 515 W | 504 W | 494 W | 483 W |
| % of rated | 99.0% | 97.4% | 95.4% | 93.4% | 91.4% | 89.4% |

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 datasheet range sits wholly inside the Australian approval of 495-540 W, so no narrowing was needed. Scored model: SG-54TG4D-540 · checked 2026-08-19. Evidence.
Sources & references · checked 2026-09-01
Strong evidence coverage
13 of 13 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 revision. Built 2026-08-19 from Sungrow's own SG-54TG4D datasheet, retrieved from info-support.sungrowpower.com via the product page and verified complete: byte count matched the declared Content-Length exactly, with %PDF magic and a trailing %%EOF. Figures read from a render of the Specifications (STC) table; the sheet also carries a separate Specifications (BNPI) table at front 1000 W/m2 and rear 135 W/m2, which runs roughly 10 per cent higher, publishes no efficiency row, and is not used here. The datasheet range 515-540 W sits wholly inside the Australian approval of 495-540 W across 10 models, so no narrowing is needed and the scored bin is the datasheet's own top. Australian warranty-terms recovery 2026-08-29: structured AU overlay terms recovered or held from the exact governing instrument. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged.

DE Support Note

- After
- The Sungrow /de-de/ smart-module path for SG-54TG4D returns 404. A global English family page plus wattage column is not SG-54TG4D-540 and is not a German sale path. Sibling SG-48, SG-54 and SG-66 families stay unmerged.

Primary datasheetAU Warranty scope
- Current text
- The datasheet states a 25-year product warranty and a 30-year linear power output warranty. Rechecked 29 August 2026: an Australian rooftop Sungrow Renewables instrument names SG-54TG4D-XXX at 25 years, while a separate official Sungrow Solar instrument names the same family at 15 years. Structured terms remain held because the governing instrument is not uniquely established.
