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-700MH-132 or Phono Solar NS-670MH-132?
According to our database: Phono Solar NS-700MH-132 has higher module efficiency (22.53% vs 21.56%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Phono Solar NS-700MH-132 and Phono Solar NS-670MH-132?
Phono Solar NS-700MH-132 has a module efficiency of 22.53%, while Phono Solar NS-670MH-132 is 21.56%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Phono Solar NS-700MH-132 use vs Phono Solar NS-670MH-132?
Phono Solar NS-700MH-132 uses N-type cells; Phono Solar NS-670MH-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-700MH-132 and Phono Solar NS-670MH-132?
Phono Solar NS-700MH-132 has a 25 years power warranty; Phono Solar NS-670MH-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.
