Performance guarantee: 25-year linear output
Wattage figure based on the sourced rated power (430 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 430 W at STC.
How this is modelled
Compounds this panel’s own published first-year (2%) and annual (0.25%/yr) degradation figures against its 430 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 (44°C) and temperature coefficient (-0.24%/°C), giving an estimated cell temperature of 60°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.

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 uses the 430 W maximum of the exact published series. Current Australian approval remains unresolved, so the product is not presented as buyer-ready in Australia. Scored model: REC430AA Pure 2 · checked 2026-08-02. Evidence.

Strong evidence coverage
25 of 26 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.
