Where each one wins
REC Alpha Pure-R REC430AA wins on wattage (400W vs 430W), efficiency (20.8% vs 22.3%), temperature coefficient (-0.34 %/°C vs -0.24 %/°C), product warranty (12 years vs 20 years), price ($168 vs $236.5). Higher wattage means fewer panels for the same system size. On a typical 8 kW residential array that is 30 fewer or extra watts per panel — meaningful when roof space is constrained.
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.
