How this is modelled

Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 660 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 (45°C) and temperature coefficient (-0.26%/°C), giving an estimated cell temperature of 61°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 the highest published rating in this exact series. Scored model: LR7-72HVH-660M · checked 2026-08-18. Evidence.

Sources & references · checked 2026-08-18

Strong evidence coverage

25 of 27 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. Re-sourced 2026-08-18. The record previously cited a Draft BGV02 revision dated 18 November 2024 covering a 630-650 W band, and carried the series name Hi-MO X10 Explorer. LONGi has retired that classification: the Hi-MO X10 range is now published as Scientist and Guardian, and the current sheet for this model is BGV03 20260509, read page-by-page because LONGi serves it as an image-only scan with no text layer. The manufacturer band moves to 640-670 W; the retained Australian range is 640-660 W because the CER export checked 2026-08-12 lists this model only across that band. The scored bin therefore moves to 660 W and the module efficiency to 24.43%.
