According to our database: **Jinko Solar JKM670N-66QL6-BDX** has higher module efficiency (**24.80%** vs **24.02%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Jinko Solar JKM480N-48QL6-DB-F4-EU and Jinko Solar JKM670N-66QL6-BDX? **Jinko Solar JKM480N-48QL6-DB-F4-EU** has a module efficiency of **24.02%**, while **Jinko Solar JKM670N-66QL6-BDX** is **24.80%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM480N-48QL6-DB-F4-EU use vs Jinko Solar JKM670N-66QL6-BDX? **Jinko Solar JKM480N-48QL6-DB-F4-EU** uses **N-type** cells; **Jinko Solar JKM670N-66QL6-BDX** 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 JKM480N-48QL6-DB-F4-EU and Jinko Solar JKM670N-66QL6-BDX? **Jinko Solar JKM480N-48QL6-DB-F4-EU** has a **30 years** power warranty; **Jinko Solar JKM670N-66QL6-BDX** 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 JKM480N-48QL6-DB-F4-EU and Jinko Solar JKM670N-66QL6-BDX bifacial panels? **Jinko Solar JKM670N-66QL6-BDX** is bifacial (captures light from both faces); **Jinko Solar JKM480N-48QL6-DB-F4-EU** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Jinko Solar JKM480N-48QL6-DB-F4-EU vs Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) - 12 differences, the largest is module efficiency - [Jinko Solar JKM480N-48QL6-DB-F4-EU vs Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W)](https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm650-670n-66ql6-bdv-f2-eu-670w) - 12 differences, the largest is module efficiency - [Jinko Solar JKM480N-48QL6-DB-F4-EU vs Jinko Solar JKM645-670N-66QL6-BDV-L](https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm645-670n-66ql6-bdv-l) - 12 differences, the largest is module efficiency - [Jinko Solar JKM480N-48QL6-DB-F4-EU vs Jinko Solar JKM670N-66QL6-BDV-F4-EU](https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm670n-66ql6-bdv-f4-eu) - 12 differences, the largest is module efficiency - [Jinko Solar JKM480N-48QL6-DB-F4-EU vs Jinko Solar JKM650-670N-66QL6-BDV (665W class)](https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm650-670n-66ql6-bdv-665w-class) - 11 differences, the largest is rated power - [Jinko Solar JKM480N-48QL6-DB-F4-EU vs Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (665W)](https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm650-670n-66ql6-bdv-f2-eu-665w) - 11 differences, the largest is rated power --- Source: https://comparepv.com/compare/jinko-solar-jkm480n-48ql6-db-f4-eu/jinko-solar-jkm670n-66ql6-bdx 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.
