Questions about this pairing
Which panel is better: Seraphim SEG-480-BTB-BG or Seraphim SRP-730-BHC-BG?
According to our database: Seraphim SRP-730-BHC-BG has higher module efficiency (23.50% vs 22.17%); Seraphim SRP-730-BHC-BG tolerates heat better (temp coeff -0.258%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Seraphim SEG-480-BTB-BG and Seraphim SRP-730-BHC-BG?
Seraphim SEG-480-BTB-BG has a module efficiency of 22.17%, while Seraphim SRP-730-BHC-BG is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Seraphim SEG-480-BTB-BG use vs Seraphim SRP-730-BHC-BG?
Seraphim SEG-480-BTB-BG uses N-type cells; Seraphim SRP-730-BHC-BG uses HJT. 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 Seraphim SEG-480-BTB-BG and Seraphim SRP-730-BHC-BG?
Seraphim SEG-480-BTB-BG has a 30 years power warranty; Seraphim SRP-730-BHC-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 Seraphim SEG-480-BTB-BG and Seraphim SRP-730-BHC-BG bifacial panels?
Both Seraphim SEG-480-BTB-BG and Seraphim SRP-730-BHC-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.
