Year 1 to year 25. Rated 440 W at STC.

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 440 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.

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 the highest published rating in this exact published US series. Scored model: Q.TRON BLK M-G2+ 440 · checked 2026-08-23. Evidence.

Sources & references · checked 2026-08-23

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 M-G2+ Rev02 April 2026 sheet, June 2026 warranty and Hanwha 2025 financials rechecked 2026-08-23.
