Our reading

Panel vision scores 71, placing 2 of 6 in the Specialist & Local class and within 0.4 points of the class leader. Its strongest scoring dimension is guarantee & backbone (89), running 9.0 points above the class average on this dimension. Durability (verified) (56) is the dimension with the most room to move. Underlying specifications include a module efficiency of 22.3%, TOPCon cell architecture, 30-year product warranty backed by a 30-year performance term.

How this is modelled

Compounds this panel’s own published first-year (1%) and annual (0.33%/yr) degradation figures against its 435 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 (43°C) and temperature coefficient (-0.3%/°C), giving an estimated cell temperature of 59°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 Panel vision 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: Panel vision AM 4.5 435 Wp · checked 2026-07-16. Evidence.

Limited evidence coverage

9 of 28 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.

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.
