How this is modelled

Compounds this panel’s own published first-year (1%) and annual (0.35%/yr) degradation figures against its 690 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 (41°C) and temperature coefficient (-0.26%/°C), giving an estimated cell temperature of 56°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.

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 G4 Infinite Ultra 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 the highest published rating in this exact series. Scored model: G4 Infinite Ultra (4th-gen ABC) · checked 2026-07-14. Evidence.

Limited evidence coverage

3 of 24 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.

Help strengthen this record

These are published evidence gaps, not private submissions. A source is reviewed under the same methodology whether it comes from a reader, installer or manufacturer.
