Questions about this pairing

Which panel is better: Avaada AVN66G12G or Adani Solar ASM-M12-132-630?
According to our database: Avaada AVN66G12G has higher module efficiency (23.18% vs 20.23%); Avaada AVN66G12G tolerates heat better (temp coeff -0.300%/°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 Avaada AVN66G12G and Adani Solar ASM-M12-132-630?
Avaada AVN66G12G has a module efficiency of 23.18%, while Adani Solar ASM-M12-132-630 is 20.23%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Avaada AVN66G12G use vs Adani Solar ASM-M12-132-630?
Avaada AVN66G12G uses TOPCon cells; Adani Solar ASM-M12-132-630 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 Avaada AVN66G12G and Adani Solar ASM-M12-132-630?
Avaada AVN66G12G has a 30 years power warranty; Adani Solar ASM-M12-132-630 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 Avaada AVN66G12G and Adani Solar ASM-M12-132-630 bifacial panels?
Avaada AVN66G12G is bifacial (captures light from both faces); Adani Solar ASM-M12-132-630 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
