What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.240 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: REC REC455AA Pure-RX or REC REC470AA Pure-RX?
According to our database: REC REC470AA Pure-RX has higher module efficiency (22.60% vs 21.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of REC REC455AA Pure-RX and REC REC470AA Pure-RX?
REC REC455AA Pure-RX has a module efficiency of 21.90%, while REC REC470AA Pure-RX is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does REC REC455AA Pure-RX use vs REC REC470AA Pure-RX?
REC REC455AA Pure-RX uses HJT cells; REC REC470AA Pure-RX uses HJT. 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 REC455AA Pure-RX and REC REC470AA Pure-RX?
REC REC455AA Pure-RX has a 25 years power warranty; REC REC470AA Pure-RX has a 25 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 REC455AA Pure-RX and REC REC470AA Pure-RX bifacial panels?
Both REC REC455AA Pure-RX and REC REC470AA Pure-RX 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.
