According to our database: **Jinko Solar JKM570N-72HL4-BDV** has higher module efficiency (**22.07%** vs **22.00%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Jinko Solar JKM570N-72HL4-BDV and Jinko Solar JKM615N-78HL4-BDV? **Jinko Solar JKM570N-72HL4-BDV** has a module efficiency of **22.07%**, while **Jinko Solar JKM615N-78HL4-BDV** is **22.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM570N-72HL4-BDV use vs Jinko Solar JKM615N-78HL4-BDV? **Jinko Solar JKM570N-72HL4-BDV** uses **N-type** cells; **Jinko Solar JKM615N-78HL4-BDV** uses **N-type**. 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 JKM570N-72HL4-BDV and Jinko Solar JKM615N-78HL4-BDV? **Jinko Solar JKM570N-72HL4-BDV** has a **30 years** power warranty; **Jinko Solar JKM615N-78HL4-BDV** 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 JKM570N-72HL4-BDV and Jinko Solar JKM615N-78HL4-BDV bifacial panels? Both **Jinko Solar JKM570N-72HL4-BDV** and **Jinko Solar JKM615N-78HL4-BDV** 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 JKM570N-72HL4-BDV vs Jinko Solar JKM620N-78HL4-BDV](https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm620n-78hl4-bdv) - 7 differences, the largest is rated power - [Jinko Solar JKM570N-72HL4-BDV vs Jinko Solar JKM610N-78HL4-BDV](https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm610n-78hl4-bdv) - 8 differences, the largest is rated power - [Jinko Solar JKM570N-72HL4-BDV vs Jinko Solar JKM605N-78HL4-BDV](https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm605n-78hl4-bdv) - 9 differences, the largest is rated power - [Jinko Solar JKM570N-72HL4-BDV vs Jinko Solar JKM580N-72HL4-BDV](https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm580n-72hl4-bdv) - 3 differences, the largest is module efficiency - [Jinko Solar JKM570N-72HL4-BDV vs Jinko Solar JKM575N-72HL4-BDV](https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm575n-72hl4-bdv) - The same specification on paper - [Jinko Solar JKM570N-72HL4-BDV vs Jinko Solar JKM565N-72HL4-BDV](https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm565n-72hl4-bdv) - One difference: module efficiency --- Source: https://comparepv.com/compare/jinko-solar-jkm570n-72hl4-bdv/jinko-solar-jkm615n-78hl4-bdv 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.
