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 (-0.290 %/°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: Jetion JT795SXt(B) or Jetion JT790SXt(B)?
According to our database: Jetion JT795SXt(B) has higher module efficiency (23.50% vs 23.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jetion JT795SXt(B) and Jetion JT790SXt(B)?
Jetion JT795SXt(B) has a module efficiency of 23.50%, while Jetion JT790SXt(B) is 23.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jetion JT795SXt(B) use vs Jetion JT790SXt(B)?
Jetion JT795SXt(B) uses TOPCon cells; Jetion JT790SXt(B) 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 Jetion JT795SXt(B) and Jetion JT790SXt(B)?
Jetion JT795SXt(B) has a 30 years power warranty; Jetion JT790SXt(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 JT795SXt(B) and Jetion JT790SXt(B) bifacial panels?
Both Jetion JT795SXt(B) and Jetion JT790SXt(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.
