Questions about this pairing

Which panel is better: REC REC460AA PURE-RX or AE Solar AE440CMD-108BDE?
According to our database: AE Solar AE440CMD-108BDE has higher module efficiency (22.57% vs 22.10%); REC REC460AA PURE-RX tolerates heat better (temp coeff -0.240%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of REC REC460AA PURE-RX and AE Solar AE440CMD-108BDE?
REC REC460AA PURE-RX has a module efficiency of 22.10%, while AE Solar AE440CMD-108BDE is 22.57%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does REC REC460AA PURE-RX use vs AE Solar AE440CMD-108BDE?
REC REC460AA PURE-RX uses HJT cells; AE Solar AE440CMD-108BDE uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on REC REC460AA PURE-RX and AE Solar AE440CMD-108BDE?
REC REC460AA PURE-RX has a 25 years power warranty; AE Solar AE440CMD-108BDE has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are REC REC460AA PURE-RX and AE Solar AE440CMD-108BDE bifacial panels?
Both REC REC460AA PURE-RX and AE Solar AE440CMD-108BDE are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
