According to our database: **Jinko Solar JKM650N-66HL4M-BDV-Z4-EU** has higher module efficiency (**24.06%** vs **23.14%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) and Jinko Solar JKM650N-66HL4M-BDV-Z4-EU? **Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (**625 W** column)** has a module efficiency of **23.14%**, while **Jinko Solar JKM650N-66HL4M-BDV-Z4-EU** is **24.06%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) use vs Jinko Solar JKM650N-66HL4M-BDV-Z4-EU? **Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (**625 W** column)** uses **N-type** cells; **Jinko Solar JKM650N-66HL4M-BDV-Z4-EU** 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 JKM605-630N-66HL4M-BDV-F3-EN (625W column) and Jinko Solar JKM650N-66HL4M-BDV-Z4-EU? **Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (**625 W** column)** has a **30 years** power warranty; **Jinko Solar JKM650N-66HL4M-BDV-Z4-EU** 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 JKM605-630N-66HL4M-BDV-F3-EN (625W column) and Jinko Solar JKM650N-66HL4M-BDV-Z4-EU bifacial panels? Both **Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (**625 W** column)** and **Jinko Solar JKM650N-66HL4M-BDV-Z4-EU** 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 JKM605-630N-66HL4M-BDV-F3-EN (625W column) vs Jinko Solar JKM625-650N-66HL4M-BDV-Z1-EN (650W)](https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-co-ltd-jkm625-650n-66hl4m-bdv-z1-en-650w) - 5 differences, the largest is module efficiency - [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) vs Jinko Solar JKM625-650N-66HL4M-BDV-Z1-EN (645W)](https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-co-ltd-jkm625-650n-66hl4m-bdv-z1-en-645w) - 4 differences, the largest is module efficiency - [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) vs Jinko Solar JKM645N-66HL4M-BDV-Z4-EU](https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-jkm645n-66hl4m-bdv-z4-eu) - 4 differences, the largest is module efficiency - [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) vs Jinko Solar JKM625-650N-66HL4M-BDV-Z1-EN (640W)](https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-co-ltd-jkm625-650n-66hl4m-bdv-z1-en-640w) - 4 differences, the largest is module efficiency - [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) vs Jinko Solar JKM640N-66HL4M-BDV-Z4-EU](https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-jkm640n-66hl4m-bdv-z4-eu) - 4 differences, the largest is module efficiency - [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (625W column) vs Jinko Solar JKM625-650N-66HL4M-BDV-Z1-EN (635W)](https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-co-ltd-jkm625-650n-66hl4m-bdv-z1-en-635w) - 4 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-625w-column/jinko-solar-jkm650n-66hl4m-bdv-z4-eu 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.
