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 REC600AA Pro MG or REC REC630AA PRO M?
According to our database: REC REC630AA PRO M has higher module efficiency (22.20% vs 21.10%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of REC REC600AA Pro MG and REC REC630AA PRO M?
REC REC600AA Pro MG has a module efficiency of 21.10%, while REC REC630AA PRO M is 22.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does REC REC600AA Pro MG use vs REC REC630AA PRO M?
REC REC600AA Pro MG uses HJT cells; REC REC630AA PRO M 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 REC600AA Pro MG and REC REC630AA PRO M?
REC REC600AA Pro MG has a 30 years power warranty; REC REC630AA PRO M 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 REC600AA Pro MG and REC REC630AA PRO M bifacial panels?
Both REC REC600AA Pro MG and REC REC630AA PRO M 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.
