Peimar DR10H450M 450W Solar Panel vs REC Alpha Pure-RX 460W Solar Panel

The REC460AA Pure-RX is the stronger panel on paper and in the field: higher efficiency, better heat and low-light behavior, lower degradation, and a warranty that covers labor. The Peimar DR10H450M is a straightforward all-black mono PERC panel that fits standard residential racking and does the job on an unshaded roof with room to spare. Buy the REC if roof space is tight or you want the longest, best-backed output; buy the Peimar if you want a clean all-black look and a simple, proven PERC build.

• Choose the Peimar DR10H450M if you have ample roof area, want a uniform all-black panel, and prefer a conventional mono PERC design that works with common racking and BOS parts.
• Choose the REC460AA Pure-RX if roof space is limited, summer heat is a concern, or you want the lowest degradation and a warranty that covers labor.
