Peimar DR10H450M 450W Solar Panel vs Canadian Solar CS6.1-54TM 450W Panel

Both are 450 W all-black panels, but they are different cell technologies. The Canadian Solar uses N-type TOPCon cells with 22.0% module efficiency and a -0.29%/°C power coefficient, so it holds output better in heat and degrades more slowly. The Peimar uses Mono PERC cells and a 1,500 V system rating, which suits larger or commercial string designs. For a typical home roof where space is tight, the Canadian Solar is the stronger pick. For a big array or a 1,500 V system, the Peimar fits better.

• Choose the Peimar 450W DR Series if you are building a 1,500 V system or a large array where string voltage headroom matters more than per-panel efficiency.
• Choose the Canadian Solar CS6.1-54TM-450 if you have limited roof space and want the highest efficiency and best heat performance from each panel.
