The verdict
Identical on every published parameter
All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

What it means on a roof
Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.340 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: Amerisolar AS-8M132-HC-655W or Amerisolar AS-8M132-HC-660W?
According to our database: Amerisolar AS-8M132-HC-660 W has higher module efficiency (21.25% vs 21.09%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Amerisolar AS-8M132-HC-655W and Amerisolar AS-8M132-HC-660W?
Amerisolar AS-8M132-HC-655 W has a module efficiency of 21.09%, while Amerisolar AS-8M132-HC-660 W is 21.25%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Amerisolar AS-8M132-HC-655W use vs Amerisolar AS-8M132-HC-660W?
Amerisolar AS-8M132-HC-655 W uses PERC cells; Amerisolar AS-8M132-HC-660 W 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 Amerisolar AS-8M132-HC-655W and Amerisolar AS-8M132-HC-660W?
Amerisolar AS-8M132-HC-655 W has a 30 years power warranty; Amerisolar AS-8M132-HC-660 W 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.
