Questions about this pairing

Which panel is better: Adani Solar ASB-M10-144-555 or Adani Solar AB-G12R-132-640?
According to our database: Adani Solar AB-G12R-132-640 has higher module efficiency (23.71% vs 21.50%); Adani Solar AB-G12R-132-640 tolerates heat better (temp coeff -0.280%/°C vs -0.320%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Adani Solar ASB-M10-144-555 and Adani Solar AB-G12R-132-640?
Adani Solar ASB-M10-144-555 has a module efficiency of 21.50%, while Adani Solar AB-G12R-132-640 is 23.71%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Adani Solar ASB-M10-144-555 use vs Adani Solar AB-G12R-132-640?
Adani Solar ASB-M10-144-555 uses TOPCon cells; Adani Solar AB-G12R-132-640 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-M10-144-555 and Adani Solar AB-G12R-132-640?
Adani Solar ASB-M10-144-555 has a 30 years power warranty; Adani Solar AB-G12R-132-640 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-M10-144-555 and Adani Solar AB-G12R-132-640 bifacial panels?
Both Adani Solar ASB-M10-144-555 and Adani Solar AB-G12R-132-640 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.
