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 (-0.240 %/°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: Jetion JT735SLk(B) or Jetion JT740SLk(B)?
According to our database: Jetion JT740SLk(B) has higher module efficiency (23.80% vs 23.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jetion JT735SLk(B) and Jetion JT740SLk(B)?
Jetion JT735SLk(B) has a module efficiency of 23.70%, while Jetion JT740SLk(B) is 23.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jetion JT735SLk(B) use vs Jetion JT740SLk(B)?
Jetion JT735SLk(B) uses HJT cells; Jetion JT740SLk(B) uses HJT. 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 Jetion JT735SLk(B) and Jetion JT740SLk(B)?
Jetion JT735SLk(B) has a 30 years power warranty; Jetion JT740SLk(B) 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 Jetion JT735SLk(B) and Jetion JT740SLk(B) bifacial panels?
Both Jetion JT735SLk(B) and Jetion JT740SLk(B) are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
