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 (-0.290 %/°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: Recom RCM-730-8DBNM or AE Solar AE CME-132-720?
According to our database: Recom RCM-730-8DBNM has higher module efficiency (23.50% vs 23.21%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Recom RCM-730-8DBNM and AE Solar AE CME-132-720?
Recom RCM-730-8DBNM has a module efficiency of 23.50%, while AE Solar AE CME-132-720 is 23.21%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Recom RCM-730-8DBNM use vs AE Solar AE CME-132-720?
Recom RCM-730-8DBNM uses TOPCon cells; AE Solar AE CME-132-720 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 Recom RCM-730-8DBNM and AE Solar AE CME-132-720?
Recom RCM-730-8DBNM has a 30 years power warranty; AE Solar AE CME-132-720 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 Recom RCM-730-8DBNM and AE Solar AE CME-132-720 bifacial panels?
Recom RCM-730-8DBNM is bifacial (captures light from both faces); AE Solar AE CME-132-720 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
