Questions about this pairing

Which panel is better: Seraphim SRP-730-BHC-BG or Seraphim SEG-490-BTB-BG?
According to our database: Seraphim SRP-730-BHC-BG has higher module efficiency (23.50% vs 22.63%); 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 SRP-730-BHC-BG and Seraphim SEG-490-BTB-BG?
Seraphim SRP-730-BHC-BG has a module efficiency of 23.50%, while Seraphim SEG-490-BTB-BG is 22.63%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Seraphim SRP-730-BHC-BG use vs Seraphim SEG-490-BTB-BG?
Seraphim SRP-730-BHC-BG uses HJT cells; Seraphim SEG-490-BTB-BG uses N-type. 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 SRP-730-BHC-BG and Seraphim SEG-490-BTB-BG?
Seraphim SRP-730-BHC-BG has a 30 years power warranty; Seraphim SEG-490-BTB-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 SRP-730-BHC-BG and Seraphim SEG-490-BTB-BG bifacial panels?
Both Seraphim SRP-730-BHC-BG and Seraphim SEG-490-BTB-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.
