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 REC630AA PRO M or REC REC630AA Pro MG?
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 REC630AA PRO M and REC REC630AA Pro MG?
REC REC630AA PRO M has a module efficiency of 22.20%, while REC REC630AA Pro MG is 22.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does REC REC630AA PRO M use vs REC REC630AA Pro MG?
REC REC630AA PRO M uses HJT cells; REC REC630AA Pro MG 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 REC630AA PRO M and REC REC630AA Pro MG?
REC REC630AA PRO M has a 25 years power warranty; REC REC630AA Pro MG 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 REC630AA PRO M and REC REC630AA Pro MG bifacial panels?
Both REC REC630AA PRO M and REC REC630AA Pro MG 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.
