Which panel is better: Adani Solar ASM-M12-132-635 or Adani Solar ASB-M12-132-650?
According to our database: Adani Solar ASB-M12-132-650 has higher module efficiency (20.87% vs 20.39%); Adani Solar ASM-M12-132-635 tolerates heat better (temp coeff -0.340%/°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 ASM-M12-132-635 and Adani Solar ASB-M12-132-650?
Adani Solar ASM-M12-132-635 has a module efficiency of 20.39%, while Adani Solar ASB-M12-132-650 is 20.87%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Adani Solar ASM-M12-132-635 use vs Adani Solar ASB-M12-132-650?
Adani Solar ASM-M12-132-635 uses PERC cells; Adani Solar ASB-M12-132-650 uses PERC. 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-M12-132-635 and Adani Solar ASB-M12-132-650?
Adani Solar ASM-M12-132-635 has a 30 years power warranty; Adani Solar ASB-M12-132-650 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-M12-132-635 and Adani Solar ASB-M12-132-650 bifacial panels?
Adani Solar ASB-M12-132-650 is bifacial (captures light from both faces); Adani Solar ASM-M12-132-635 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
