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 (-0.280 %/°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: Adani Solar AB-G12R-132-640 or Adani Solar AB-G12R-132-610?
According to our database: Adani Solar AB-G12R-132-640 has higher module efficiency (23.71% vs 22.60%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Adani Solar AB-G12R-132-640 and Adani Solar AB-G12R-132-610?
Adani Solar AB-G12R-132-640 has a module efficiency of 23.71%, while Adani Solar AB-G12R-132-610 is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Adani Solar AB-G12R-132-640 use vs Adani Solar AB-G12R-132-610?
Adani Solar AB-G12R-132-640 uses TOPCon cells; Adani Solar AB-G12R-132-610 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 Adani Solar AB-G12R-132-640 and Adani Solar AB-G12R-132-610?
Adani Solar AB-G12R-132-640 has a 30 years power warranty; Adani Solar AB-G12R-132-610 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 Adani Solar AB-G12R-132-640 and Adani Solar AB-G12R-132-610 bifacial panels?
Both Adani Solar AB-G12R-132-640 and Adani Solar AB-G12R-132-610 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.
