What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (515 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 515 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 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 (-0.29%/°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.

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 AU rating for this exact series. Scored model: TSM-NEG18R.25 · checked 2026-07-16. 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. Exact family documentation reviewed 2026-08-06 Corrected 2026-08-19: the LeTID resistance claim is withdrawn. It was attributed to this product's datasheet, and neither the archived copy nor the live file contains any LeTID, LID or light-induced string. No score changes: the field is unscored. 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.
