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 JT790SXt(B) and Jetion JT795SXt(B)? **Jetion JT790SXt(B)** has a module efficiency of **23.40%**, while **Jetion JT795SXt(B)** is **23.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jetion JT790SXt(B) use vs Jetion JT795SXt(B)? **Jetion JT790SXt(B)** uses **TOPCon** cells; **Jetion JT795SXt(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 JT790SXt(B) and Jetion JT795SXt(B)? **Jetion JT790SXt(B)** has a **30 years** power warranty; **Jetion JT795SXt(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 JT790SXt(B) and Jetion JT795SXt(B) bifacial panels? Both **Jetion JT790SXt(B)** and **Jetion JT795SXt(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. ## Related comparisons - [Jetion JT790SXt(B) vs Jetion JT800SXt(B)](https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt800sxt-b) - 2 differences, the largest is module efficiency - [Jetion JT790SXt(B) vs Jetion JT785SXt(B)](https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt785sxt-b) - One difference: module efficiency - [Jetion JT790SXt(B) vs Jetion JT780SXt(B)](https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt780sxt-b) - 2 differences, the largest is module efficiency - [Jetion JT790SXt(B) vs Jetion JT775SXt(B)](https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt775sxt-b) - 3 differences, the largest is module efficiency - [Jetion JT790SXt(B) vs Jetion JT755SLk(B)](https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt755slk-b) - 14 differences, the largest is module efficiency - [Jetion JT790SXt(B) vs Jetion JT750SLk(B)](https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt750slk-b) - 14 differences, the largest is temperature coefficient --- Source: https://comparepv.com/compare/jetion-jt790sxt-b/jetion-jt795sxt-b Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
