Questions about this pairing

Which panel is better: Adani Solar ASB-M12-132-640 or Adani Solar AB-G12R-132-610?
According to our database: Adani Solar AB-G12R-132-610 has higher module efficiency (22.60% vs 20.55%); Adani Solar AB-G12R-132-610 tolerates heat better (temp coeff -0.280%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Adani Solar ASB-M12-132-640 and Adani Solar AB-G12R-132-610?
Adani Solar ASB-M12-132-640 has a module efficiency of 20.55%, 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 ASB-M12-132-640 use vs Adani Solar AB-G12R-132-610?
Adani Solar ASB-M12-132-640 uses PERC 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 ASB-M12-132-640 and Adani Solar AB-G12R-132-610?
Adani Solar ASB-M12-132-640 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 ASB-M12-132-640 and Adani Solar AB-G12R-132-610 bifacial panels?
Both Adani Solar ASB-M12-132-640 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
