Questions about this pairing
Which panel is better: Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505W) or Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
According to our database: Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) has higher module efficiency (23.66% vs 23.36%); Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505 W) tolerates heat better (temp coeff -0.260%/°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 JKM495-520N-51QL6-BDV-F2-EU (505W) and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505 W) has a module efficiency of 23.36%, while Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) is 23.66%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505W) use vs Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505 W) uses TOPCon cells; Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) 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 JKM495-520N-51QL6-BDV-F2-EU (505W) and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505 W) has a 30 years power warranty; Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) 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 JKM495-520N-51QL6-BDV-F2-EU (505W) and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin) bifacial panels?
Both Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (505 W) and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) 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.
