According to our database: **Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (**725 W** bin)** has higher module efficiency (**23.34%** vs **23.30%**); **Tongwei TWMNF-66HD725** tolerates heat better (temp coeff **-0.280%/°C** vs **-0.290%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) and Tongwei TWMNF-66HD725? **Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (**725 W** bin)** has a module efficiency of **23.34%**, while **Tongwei TWMNF-66HD725** is **23.30%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) use vs Tongwei TWMNF-66HD725? **Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (**725 W** bin)** uses **TOPCon** cells; **Tongwei TWMNF-66HD725** 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 JKM710-735N-66HL5-BDV-Z3-EU (725W bin) and Tongwei TWMNF-66HD725? **Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (**725 W** bin)** has a **30 years** power warranty; **Tongwei TWMNF-66HD725** 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 JKM710-735N-66HL5-BDV-Z3-EU (725W bin) and Tongwei TWMNF-66HD725 bifacial panels? Both **Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (**725 W** bin)** and **Tongwei TWMNF-66HD725** 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 JKM710-735N-66HL5-BDV-Z3-EU (725W bin) vs Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)](https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-735w-bin) - 3 differences, the largest is module efficiency - [Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) vs Jinko Solar JKM735N-66HL5-BDV-Z3-EU](https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/jinko-solar-jkm735n-66hl5-bdv-z3-eu) - 3 differences, the largest is module efficiency - [Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) vs Jinko Solar JKM735N-66HL5-BDV-Z6-EU](https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/jinko-solar-jkm735n-66hl5-bdv-z6-eu) - 3 differences, the largest is module efficiency - [Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) vs Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (730W bin)](https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-730w-bin) - The same specification on paper - [Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) vs Jinko Solar JKM730N-66HL5-BDV-Z3-EU](https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/jinko-solar-jkm730n-66hl5-bdv-z3-eu) - The same specification on paper - [Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (725W bin) vs Jinko Solar JKM730N-66HL5-BDV-Z6-EU](https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/jinko-solar-jkm730n-66hl5-bdv-z6-eu) - The same specification on paper --- Source: https://comparepv.com/compare/jinkosolar-jkm710-735n-66hl5-bdv-z3-eu-725w-bin/tongwei-solar-twmnf-66hd725 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.
