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 (-0.420 %/°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: Jinko Solar JS320P or Jinko Solar JS325P?
According to our database: Jinko Solar JS325P has higher module efficiency (16.70% vs 16.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JS320P and Jinko Solar JS325P?
Jinko Solar JS320P has a module efficiency of 16.40%, while Jinko Solar JS325P is 16.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JS320P use vs Jinko Solar JS325P?
Jinko Solar JS320P uses PERC cells; Jinko Solar JS325P 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 Jinko Solar JS320P and Jinko Solar JS325P?
Jinko Solar JS320P has a 25 years power warranty; Jinko Solar JS325P has a 25 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.
