Market position
The data
Performance guarantee: 30-year linear output
Wattage figure based on the sourced rated power (505 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. Rated 505 W at STC.
How this is modelled
Modelled from this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures, compounded against its 505 W rated (STC) output. This is a datasheet-derived estimate, not a field measurement or a warranty guarantee. Actual output also depends on site irradiance, temperature, soiling and system design.
| Year | 1 | 5 | 10 | 15 | 20 | 25 |
|---|---|---|---|---|---|---|
| Watts | 500 W | 493 W | 484 W | 475 W | 466 W | 458 W |
| % of rated | 99.0% | 97.6% | 95.8% | 94.1% | 92.3% | 90.6% |
Two things to check
Ask the installer: Will the quote name the exact Max 54-cell 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 HSM-BE54-HD505, the 505 W top bin in the current Australian SunPower Max series manufactured by TCL. Warranty scope remains under review because the current warranty table names HSM-BE52-HD490-505 rather than the BE54 datasheet family. Scored model: HSM-BE54-HD505 · checked 2026-07-27. Evidence.

Strong evidence coverage
27 of 27 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.
