Phono Solar NS-665MH-132 vs Phono Solar NS-660MH-132
VS
The verdict
Identical on every published parameter
All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. 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
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°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: Phono Solar NS-665MH-132 or Phono Solar NS-660MH-132?
According to our database: Phono Solar NS-665MH-132 has higher module efficiency (21.40% vs 21.24%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Phono Solar NS-665MH-132 and Phono Solar NS-660MH-132?
Phono Solar NS-665MH-132 has a module efficiency of 21.40%, while Phono Solar NS-660MH-132 is 21.24%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Phono Solar NS-665MH-132 use vs Phono Solar NS-660MH-132?
Phono Solar NS-665MH-132 uses TOPCon cells; Phono Solar NS-660MH-132 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 Phono Solar NS-665MH-132 and Phono Solar NS-660MH-132?
Phono Solar NS-665MH-132 has a 30 years power warranty; Phono Solar NS-660MH-132 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.
