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 (500 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 500 W at STC.
How this is modelled
Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 500 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 LR7-54HVH-490M, the highest current Australian approved bin in the exact 475-490 W series. Scored model: LR7-54HVH-500M · checked 2026-08-18. Evidence.
Sources & references · checked 2026-08-18
Strong evidence coverage
27 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 an Explorer-era sheet covering a 475-490 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 480-505 W; the retained Australian range is 480-500 W because the CER export checked 2026-08-12 lists this model only across that band. The scored bin therefore moves to 500 W and the module efficiency to 24.5%.

- After
- The CER approved PV module export checked 2026-08-12 lists exact LR7-54HVH models across 480-500 W. The retained range is the intersection of that listing with the current manufacturer sheet, which spans 480-505 W.
