Our reading

Vertex S+ G3 78-cell scores 70, placing 18 of 51 in the Global Tier-1 class against a class average of 66.1. Its strongest scoring dimension is architecture & design (84), running 9.7 points above the class average on this dimension. Durability (verified) (56) is the dimension with the most room to move. Underlying specifications include a module efficiency of 24.65%, N-type TOPCon cell technology, 15-year product warranty backed by a 30-year performance term.

How this is modelled

Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 515 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 (43°C) and temperature coefficient (-0.26%/°C), giving an estimated cell temperature of 59°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. The score is anchored to TSM-515NEG10R.28Z, the highest published rating in the exact Australia-exclusive Vertex S+ G3 series. Scored model: TSM-515NEG10R.28Z · checked 2026-08-07. Evidence.

Strong evidence coverage

27 of 28 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. Trinasolar TSM_AUS_EN_2026_PA5, global warranty PS-M-0135 PAC1 and CER export checked 2026-08-07 LeTID re-verified 2026-08-19 for rubric v2.12.0: scored under the returned criterion on the evidence recorded in its provenance. Re-verification 2026-08-19: Verified reliability recorded as "Brand or series independently tested; exact model not covered" under panel rubric v2.13.0, which added a band for brand or series evidence where the exact model is not covered by the third-party record.
