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.
