According to our database: **Jinko Solar JKM625-650N-78HL4-BDV (**645 W**)** has higher module efficiency (**23.07%** vs **22.45%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Jinko Solar JKM575-600N-72HL4-BDV (580W) and Jinko Solar JKM625-650N-78HL4-BDV (645W)? **Jinko Solar JKM575-600N-72HL4-BDV (**580 W**)** has a module efficiency of **22.45%**, while **Jinko Solar JKM625-650N-78HL4-BDV (**645 W**)** is **23.07%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM575-600N-72HL4-BDV (580W) use vs Jinko Solar JKM625-650N-78HL4-BDV (645W)? **Jinko Solar JKM575-600N-72HL4-BDV (**580 W**)** uses **TOPCon** cells; **Jinko Solar JKM625-650N-78HL4-BDV (**645 W**)** 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 Jinko Solar JKM575-600N-72HL4-BDV (580W) and Jinko Solar JKM625-650N-78HL4-BDV (645W)? **Jinko Solar JKM575-600N-72HL4-BDV (**580 W**)** has a **30 years** power warranty; **Jinko Solar JKM625-650N-78HL4-BDV (**645 W**)** 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 Jinko Solar JKM575-600N-72HL4-BDV (580W) and Jinko Solar JKM625-650N-78HL4-BDV (645W) bifacial panels? Both **Jinko Solar JKM575-600N-72HL4-BDV (**580 W**)** and **Jinko Solar JKM625-650N-78HL4-BDV (**645 W**)** 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 - [Jinko Solar JKM575-600N-72HL4-BDV (580W) vs Jinko Solar JKM625-650N-78HL4-BDV (650W)](https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-co-ltd-jkm625-650n-78hl4-bdv-650w) - 9 differences, the largest is module efficiency - [Jinko Solar JKM575-600N-72HL4-BDV (580W) vs Jinko Solar JKM625-650N-78HL4-BDV](https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-co-ltd-jkm625-650n-78hl4-bdv) - 9 differences, the largest is module efficiency - [Jinko Solar JKM575-600N-72HL4-BDV (580W) vs Jinko Solar JKM650N-78HL4-BDV-F9-EU](https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-co-ltd-jkm650n-78hl4-bdv-f9-eu) - 9 differences, the largest is module efficiency - [Jinko Solar JKM575-600N-72HL4-BDV (580W) vs Jinko Solar JKM650N-78HL4-BDV](https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-jkm650n-78hl4-bdv) - 9 differences, the largest is module efficiency - [Jinko Solar JKM575-600N-72HL4-BDV (580W) vs Jinko Solar JKM645N-78HL4-BDV-F9-EU](https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-co-ltd-jkm645n-78hl4-bdv-f9-eu) - 9 differences, the largest is rated power - [Jinko Solar JKM575-600N-72HL4-BDV (580W) vs Jinko Solar JKM645N-78HL4-BDV](https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-jkm645n-78hl4-bdv) - 9 differences, the largest is rated power --- Source: https://comparepv.com/compare/jinko-solar-co-ltd-jkm575-600n-72hl4-bdv-580w/jinko-solar-co-ltd-jkm625-650n-78hl4-bdv-645w 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.
