According to our database: **Jinko Solar JKM735N-66HL5-BDV-Z3-EU** has higher module efficiency (**23.66%** 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 JKM625N-66HL4M-BDV and Jinko Solar JKM735N-66HL5-BDV-Z3-EU? **Jinko Solar JKM625N-66HL4M-BDV** has a module efficiency of **23.14%**, while **Jinko Solar JKM735N-66HL5-BDV-Z3-EU** is **23.66%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM625N-66HL4M-BDV use vs Jinko Solar JKM735N-66HL5-BDV-Z3-EU? **Jinko Solar JKM625N-66HL4M-BDV** uses **N-type** cells; **Jinko Solar JKM735N-66HL5-BDV-Z3-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 JKM625N-66HL4M-BDV and Jinko Solar JKM735N-66HL5-BDV-Z3-EU? **Jinko Solar JKM625N-66HL4M-BDV** has a **30 years** power warranty; **Jinko Solar JKM735N-66HL5-BDV-Z3-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 JKM625N-66HL4M-BDV and Jinko Solar JKM735N-66HL5-BDV-Z3-EU bifacial panels? Both **Jinko Solar JKM625N-66HL4M-BDV** and **Jinko Solar JKM735N-66HL5-BDV-Z3-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 JKM625N-66HL4M-BDV vs Jinko Solar JKM640N-66HL4M-BDV](https://comparepv.com/compare/jinko-solar-jkm625n-66hl4m-bdv/jinko-solar-jkm640n-66hl4m-bdv) - 3 differences, the largest is module efficiency - [Jinko Solar JKM625N-66HL4M-BDV vs Jinko Solar JKM635N-66HL4M-BDV](https://comparepv.com/compare/jinko-solar-jkm625n-66hl4m-bdv/jinko-solar-jkm635n-66hl4m-bdv) - 3 differences, the largest is module efficiency - [Jinko Solar JKM625N-66HL4M-BDV vs Jinko Solar JKM630N-66HL4M-BDV](https://comparepv.com/compare/jinko-solar-jkm625n-66hl4m-bdv/jinko-solar-jkm630n-66hl4m-bdv) - The same specification on paper - [Jinko Solar JKM625N-66HL4M-BDV vs Jinko Solar JKM620N-66HL4M-BDV](https://comparepv.com/compare/jinko-solar-jkm625n-66hl4m-bdv/jinko-solar-jkm620n-66hl4m-bdv) - The same specification on paper - [Jinko Solar JKM625N-66HL4M-BDV vs Jinko Solar JKM615N-66HL4M-BDV](https://comparepv.com/compare/jinko-solar-jkm625n-66hl4m-bdv/jinko-solar-jkm615n-66hl4m-bdv) - 3 differences, the largest is module efficiency - [Jinko Solar JKM735N-66HL5-BDV-Z3-EU vs Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)](https://comparepv.com/compare/jinko-solar-jkm735n-66hl5-bdv-z3-eu/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-735w-bin) - The same specification on paper --- Source: https://comparepv.com/compare/jinko-solar-jkm625n-66hl4m-bdv/jinko-solar-jkm735n-66hl5-bdv-z3-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.
