Questions about this pairing

Which panel is better: Adani Solar ASM-M12-132-650 or Adani Solar AB-G12R-132-630?
According to our database: Adani Solar AB-G12R-132-630 has higher module efficiency (23.34% vs 20.87%); Adani Solar AB-G12R-132-630 tolerates heat better (temp coeff -0.280%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Adani Solar ASM-M12-132-650 and Adani Solar AB-G12R-132-630?
Adani Solar ASM-M12-132-650 has a module efficiency of 20.87%, while Adani Solar AB-G12R-132-630 is 23.34%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Adani Solar ASM-M12-132-650 use vs Adani Solar AB-G12R-132-630?
Adani Solar ASM-M12-132-650 uses PERC cells; Adani Solar AB-G12R-132-630 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 ASM-M12-132-650 and Adani Solar AB-G12R-132-630?
Adani Solar ASM-M12-132-650 has a 30 years power warranty; Adani Solar AB-G12R-132-630 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 ASM-M12-132-650 and Adani Solar AB-G12R-132-630 bifacial panels?
Adani Solar AB-G12R-132-630 is bifacial (captures light from both faces); Adani Solar ASM-M12-132-650 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

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.
