Where each one wins
CW Energy CWT450 108TNFB10 wins on efficiency (23.04% vs 20.82%), temperature coefficient (-0.3 %/°C vs -0.37 %/°C), price ($184.5 vs $153). 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.
