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 (43°C) and temperature coefficient (-0.26%/°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.

Before you buy

Two things to check

Local positionUse a market view to check local availability, approvals and warranty scope.

Ask the installer: Will the quote name the exact Hi-MO 9 72HYD model and wattage, and who covers labour if the module warranty is used?

Verification & sources

Market context

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: LR7-72HYD-660M · checked 2026-07-27. Evidence.

Strong evidence coverage

22 of 30 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.

Help strengthen this record

These are published evidence gaps, not private submissions. A source is reviewed under the same methodology whether it comes from a reader, installer or manufacturer.
