According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Jinko Solar JKM450-475N-48HL4M-DV and Jinko Solar JKM450-475N-48HL4M-DV (475W class)? **Jinko Solar JKM450-475N-48HL4M-DV** has a module efficiency of **23.77%**, while **Jinko Solar **JKM450-475N-48HL4M-DV** (**475 W** class)** is **23.77%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM450-475N-48HL4M-DV use vs Jinko Solar JKM450-475N-48HL4M-DV (475W class)? **Jinko Solar JKM450-475N-48HL4M-DV** uses **TOPCon** cells; **Jinko Solar **JKM450-475N-48HL4M-DV** (**475 W** class)** 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 JKM450-475N-48HL4M-DV and Jinko Solar JKM450-475N-48HL4M-DV (475W class)? **Jinko Solar JKM450-475N-48HL4M-DV** has a **30 years** power warranty; **Jinko Solar **JKM450-475N-48HL4M-DV** (**475 W** class)** 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. ## Related comparisons - [Jinko Solar JKM450-475N-48HL4M-DV (475W class) vs Jinko Solar JKM450-475N-48HL4M-DV (470W class)](https://comparepv.com/compare/jinko-solar-jkm450-475n-48hl4m-dv-475w-class/jinko-solar-jkm450-475n-48hl4m-dv-470w-class) - One difference: module efficiency - [Jinko Solar JKM450-475N-48HL4M-DV (475W class) vs Jinko Solar JKM450-475N-48HL4M-DV (465W class)](https://comparepv.com/compare/jinko-solar-jkm450-475n-48hl4m-dv-475w-class/jinko-solar-jkm450-475n-48hl4m-dv-465w-class) - 3 differences, the largest is module efficiency - [Jinko Solar JKM450-475N-48HL4M-DV (475W class) vs Jinko Solar JKM450-475N-48HL4M-DV (460W class)](https://comparepv.com/compare/jinko-solar-jkm450-475n-48hl4m-dv-475w-class/jinko-solar-jkm450-475n-48hl4m-dv-460w-class) - 3 differences, the largest is module efficiency - [Jinko Solar JKM450-475N-48HL4M-DV (475W class) vs Jinko Solar JKM450-475N-48HL4M-DV (455W class)](https://comparepv.com/compare/jinko-solar-jkm450-475n-48hl4m-dv-475w-class/jinko-solar-jkm450-475n-48hl4m-dv-455w-class) - 4 differences, the largest is module efficiency - [Jinko Solar JKM450-475N-48HL4M-DV (475W class) vs Jinko Solar JKM450-475N-48HL4M-DV (450W class)](https://comparepv.com/compare/jinko-solar-jkm450-475n-48hl4m-dv-475w-class/jinko-solar-jkm450-475n-48hl4m-dv-450w-class) - 5 differences, the largest is module efficiency - [Jinko Solar JKM450-475N-48HL4M-DV vs Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)](https://comparepv.com/compare/jinko-solar-co-ltd-jkm450-475n-48hl4m-dv/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-735w-bin) - 11 differences, the largest is rated power --- Source: https://comparepv.com/compare/jinko-solar-co-ltd-jkm450-475n-48hl4m-dv/jinko-solar-jkm450-475n-48hl4m-dv-475w-class 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.
