How this is modelled

Modelled from this panel’s own published first-year (1.5%) and annual (0.33%/yr) degradation figures, compounded against its 445 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.

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 rating in this exact series. Scored model: Q.TRON BLK S-G3R.12+/BFG 445 · checked 2026-08-01. Evidence.

Strong evidence coverage

24 of 24 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. Q.TRON BLK S-G3R.12+/BFG exact Rev01 sheet rechecked 2026-08-23; LeTID and PID scope linked and unsupported Advanced MBB scoring detail withheld. AU, US and DE remain unavailable for the exact record. India existing-catalogue panel ALMM review 2026-09-02: IN overlays recorded against List-I revision 03.08.2026; scores unchanged.
