How this is modelled

Modelled from this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures, compounded against its 550 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.

Two things to check

Local positionUse a market view to check local availability, approvals and warranty scope.

Ask the installer: Will the quote name the exact DeepBlue 5.0 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 global and anchored to the highest published rating in this exact physical series. The exact Australian physical series remains under review. Scored model: JAM54D50-550/GR · checked 2026-07-31. Evidence.

Strong evidence coverage

14 of 14 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.
