Where each one wins
Aptos DNA-120-BF10-460W wins on wattage (460W vs 440W), product warranty (30 years vs 12 years), price ($193.2 vs $154). Higher wattage means fewer panels for the same system size. On a typical 8 kW residential array that is 20 fewer or extra watts per panel — meaningful when roof space is constrained.
ZNShine ZXM7-UHLDD108 wins on efficiency (21.26% vs 22.53%), temperature coefficient (-0.35 %/°C vs -0.3 %/°C). Module efficiency is what determines watts-per-square-meter. The higher number wins on tight roofs; below ~21.5% you start needing extra panels to hit the same system size.
The right pick depends on which dimensions matter most to you. The spec table above lays out the full envelope; the chat panel below answers "which one for {use case}" if you want a directed recommendation.
