Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (625 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, at 30°C and 1000 W/m². Rated 625 W at STC.
How this is modelled
Compounds this panel’s own published first-year (1%) and annual (0.4%/yr) degradation figures against its 625 W rated (STC) output, then derates for the ambient and irradiance selected. Output is scaled roughly linearly with irradiance (1000 W/m² against the 1000 W/m² STC reference). This is the dominant real-world effect at low light, whether from cloud, shading or soiling. Output is then further derated for heat, from this panel’s own NOCT (41°C) and temperature coefficient (-0.29%/°C), giving an estimated cell temperature of 56°C at that ambient and irradiance. A datasheet-derived estimate, not a field measurement or a warranty guarantee: it does not account for this panel’s own low-light efficiency response (a separate, less-consistently-published spec), or for wind and system design. See NOCT and temperature coefficient in the glossary.

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 is anchored to the highest published Australian rating in this exact series. Scored model: CS6.1-72TD-625 · checked 2026-08-06. Evidence.
Sources & references · checked 2026-09-01
Strong evidence coverage
27 of 27 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.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them. How the evidence puzzle works
Record correction. TOPHiKu6 CS6.1-72TD exact Australian V1.6 sheet rechecked 2026-08-23; fire and tolerance linked and unsupported MBB detail withheld while AU status remains available. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged. Carbon evidence corrected 2026-10-04: the cited below-400 kg/kWp figure covers HiHero HJT and does not establish this CS6.1-72TD TOPCon product. Canadian Solar publishes corporate carbon-reduction/ESG information; an exact 72TD EPD and certified manufacturing intensity were not established in the reviewed official sources. EPDITALY0340 names MS-family modules and MR-EPDITALY0105 names other model codes; their results are not transferred. The corporate-disclosure rubric band replaces the unsupported low-carbon band. This is an evidence-scope correction, not a measured finding of poor carbon performance or proof that no declaration exists. The exact Australian 625 W benchmark and other technical values are unchanged; production/BOM and measurement boundaries remain unresolved.

AU Warranty scope
- Before
- Australia and New Zealand; TopHiKu warranty V2.0 explicitly includes CS6.1-72TD, with 12-year product and 30-year power cover at 99% after year 1, 0.4% annual degradation and 87.4% at year 30.
- After
- Australia and New Zealand, for products delivered under a sales contract or purchase order signed on or after 30 May 2026. The TOPHiKu Limited Warranty Statement (AU-Rev TOPHiKu 2.0, May 2026) names CS6.1-72TD-XXX (IEC1500V), with a 12-year product warranty and a 30-year performance warranty: no less than 99% of labelled output during the first year, annual decline no more than 0.4% from year 2, and no less than 87.4% at the end of year 30. Output is verified at Standard Testing Conditions only, with measurement uncertainty applied.
AU Support Note
- Before
- Canadian Solar publishes the exact 595-625 W Australian series and current regulatory evidence for the scored 625 W suffix.
- After
- Canadian Solar publishes the exact 595-625 W Australian series datasheet (V1.6_AU). The Clean Energy Regulator approved PV module export, version of 24 September 2026, lists CS6.1-72TD-625 (IEC1500V) (IEC 61215-2021), approved 12 June 2024 and expiring 12 June 2027.
