How this is modelled

Compounds this panel’s own published first-year (2%) and annual (0.25%/yr) degradation figures against its 475 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.

Read the Australian warranty as a claim pathway: the headline term is separate from remedy, labour, freight, site work, transfer and registration conditions.

    Australian evidence checked 2026-08-07.

    Covered6 sources

    Australian warranty scope: Australia; REC Alpha warranty Rev 8 explicitly names Alpha Pure-RX and REC Solar Pte. Ltd. as warrantor. Standard cover is 20 years product and 25 years performance, with 98% in year one, 0.25% later annual degradation and 92% at year 25. Conditional REC ProTrust can extend product and labour benefits when its installer, registration and system-size conditions are met.

    Structured claim terms: Recorded.

    Term
    20 yr product / 25 yr performanceStated in the structured comparison
    Product remedy
    ConditionalAt REC's choice: repair, equivalent replacement or refund of the current market price; a performance claim may instead receive additional panels.
    Labour
    Not coveredThe standard warranty excludes on-site labour. Eligible REC ProTrust systems receive a fixed labour payment to an REC Certified Solar Professional, not uncapped labour cover.
    Freight
    ConditionalREC covers non-air transport to a REC-designated facility. Freight beyond that facility, including delivery to the buyer's site, is discretionary case by case.
    Removal and reinstallation
    Not coveredThe standard warranty excludes de-installation, removal and reinstallation costs.
    Transferability
    ConditionalTransfers to a subsequent owner of the same unaltered solar facility while the panels remain installed at the original property. Proof of each sale is required with a claim.
    Registration and conditions
    ConditionalNo pre-registration is required for the standard warranty. ProTrust requires an REC Certified Solar Professional installation and installer registration with REC.
