Effective power output over time
Year 1 to year 25, at 30°C and 1000 W/m². Rated 645 W at STC.
How this is modelled
Compounds this panel’s own published first-year (1%) and annual (0.3%/yr) degradation figures against its 645 W rated (STC) output, then derates for the ambient and irradiance selected. Output is scaled roughly linearly with irradiance (1000W/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 (-0.24%/°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.

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. Retained scope is the intersection of the reviewed datasheet (620-645 W) with the Australian approval (615-665 W across 20 models). The approval extends beyond the reviewed sheet, so a later datasheet exists that was not located; the scored bin is the highest the reviewed source establishes, not the highest approved. Scored model: CS6.2-66HB-645 · checked 2026-08-18. Evidence.
Sources & references · checked 2026-09-01
Strong evidence coverage
22 of 22 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. Built 2026-08-18 from Canadian Solar's HiHero+ HJT datasheet v1.5 (EN), text layer intact and cross-read against a render. Cell Type is given verbatim as "HJT cells". Scope note: the datasheet covers 620-645 W while the Australian approval runs 615-665 W across 20 models, so a later sheet exists that was not located; this record is scoped to the intersection of the reviewed sheet and the listing. The cover claims "Up to 95% Power Bifaciality" but the electrical table gives 90% with a +/-5% tolerance; the table value is recorded. Re-verification 2026-08-18: salt mist recorded as certified without published severity from the Clean Energy Council enhanced listing for exact model CS6.2-66HB-645, under panel rubric v2.11.0 which added that band. LeTID re-verified 2026-08-19 for rubric v2.12.0: scored under the returned criterion on the evidence recorded in its provenance. 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.

Our reading
HiHero+ CS6.2-66HB scores 75, labelled Superior. That 75 is the displayed badge. It is the homepage Premium Performance champion because Maxeon 7, also displayed at 76, is financially flagged and therefore not eligible. Active ranked class size is 53. Strongest dimension on this card is efficiency and yield (84), 16.7 points above the class average of 67.5. Guarantee and backbone is 58. Published specifications on this card: 23.9 per cent module efficiency, N-type HJT, 15-year product warranty backed by a 30-year performance term. Scored model CS6.2-66HB-645.
