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 REC470AA Pure-RX or REC REC Alpha Pure-RX 470 Wp?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of REC REC470AA Pure-RX and REC REC Alpha Pure-RX 470 Wp?
REC REC470AA Pure-RX has a module efficiency of 22.60%, while REC REC Alpha Pure-RX 470 Wp is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does REC REC470AA Pure-RX use vs REC REC Alpha Pure-RX 470 Wp?
REC REC470AA Pure-RX uses HJT cells; REC REC Alpha Pure-RX 470 Wp 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 REC470AA Pure-RX and REC REC Alpha Pure-RX 470 Wp?
REC REC470AA Pure-RX has a 25 years power warranty; REC REC Alpha Pure-RX 470 Wp 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 REC470AA Pure-RX and REC REC Alpha Pure-RX 470 Wp bifacial panels?
REC REC470AA Pure-RX is bifacial (captures light from both faces); REC REC Alpha Pure-RX 470 Wp is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
