Questions about this pairing
Which panel is better: Jinko Solar JKM650-670N-66QL6-BDV (650W class) or Seraphim SRP-630-BTZ-BG?
According to our database: Jinko Solar JKM650-670N-66QL6-BDV (650 W class) has higher module efficiency (24.06% vs 22.54%); Jinko Solar JKM650-670N-66QL6-BDV (650 W class) 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 JKM650-670N-66QL6-BDV (650W class) and Seraphim SRP-630-BTZ-BG?
Jinko Solar JKM650-670N-66QL6-BDV (650 W class) has a module efficiency of 24.06%, while Seraphim SRP-630-BTZ-BG is 22.54%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM650-670N-66QL6-BDV (650W class) use vs Seraphim SRP-630-BTZ-BG?
Jinko Solar JKM650-670N-66QL6-BDV (650 W class) uses TOPCon cells; Seraphim SRP-630-BTZ-BG 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 JKM650-670N-66QL6-BDV (650W class) and Seraphim SRP-630-BTZ-BG?
Jinko Solar JKM650-670N-66QL6-BDV (650 W class) has a 30 years power warranty; Seraphim SRP-630-BTZ-BG 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 JKM650-670N-66QL6-BDV (650W class) and Seraphim SRP-630-BTZ-BG bifacial panels?
Both Jinko Solar JKM650-670N-66QL6-BDV (650 W class) and Seraphim SRP-630-BTZ-BG 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.
