The assessment
How it scores, by category
Market position
The data
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (455 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 455 W at STC.
Compounds this panel’s own published first-year (1%) and annual (0.4%/yr) degradation figures against its 455 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 (-0.29%/°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.

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.
Ask the installer: Will the quote name the exact Sable BTE-BG 48-cell model and wattage, and who covers labour if the module warranty is used?

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 SRP-455-BTE-BG, the highest current Australian approved bin. Globally documented 435 W and 460 W bins are excluded from the Australian range. Scored model: SRP-455-BTE-BG · checked 2026-08-02. Evidence.

Australian warranty scope: The governing 2025 dual-glass warranty expressly includes SRP-XXX-BTE-BG. It provides a 15-year product warranty and a 30-year TOPCon performance warranty ending at 87.4%. Authorised documented shipping may be reimbursed, but installation, removal, reinstallation, customs and transit insurance are excluded.
Structured claim terms: Recorded.
