How it scores, by category
Market position
The data
Performance guarantee: 25-year linear output
Wattage figure based on the sourced rated power (450 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 450 W at STC.
Compounds this panel’s own published first-year (1%) and annual (0.4%/yr) degradation figures against its 450 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 (42°C) and temperature coefficient (-0.3%/°C), giving an estimated cell temperature of 58°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.

System decision
Only exact, manufacturer-named Australian paths are shown. A shared brand, product family or output rating is not proof of compatibility.
Exact pairing not recorded
No exact manufacturer-named inverter, battery or integrated-system pairing is recorded for Australia. This is a documentation state, not a finding that the product cannot be used in a system.
A documented relation does not establish site sizing, network approval, protected-load design, firmware state or installer acceptance. When no exact relation is recorded, compatibility remains unestablished in this catalogue.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The 450 W bin exists only in datasheet Rev.01; the California list still carries a 415 W bin the current sheet dropped. Scored model: 108HC-450 M10 NTYP SL Bifacial · checked 2026-08-04. Evidence.

Strong evidence coverage
29 of 29 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.
