What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.258 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: Seraphim SRP-710-BHC-BG or Seraphim SRP-705-BHC-BG?
According to our database: Seraphim SRP-710-BHC-BG has higher module efficiency (22.86% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Seraphim SRP-710-BHC-BG and Seraphim SRP-705-BHC-BG?
Seraphim SRP-710-BHC-BG has a module efficiency of 22.86%, while Seraphim SRP-705-BHC-BG is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Seraphim SRP-710-BHC-BG use vs Seraphim SRP-705-BHC-BG?
Seraphim SRP-710-BHC-BG uses HJT cells; Seraphim SRP-705-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 SRP-710-BHC-BG and Seraphim SRP-705-BHC-BG?
Seraphim SRP-710-BHC-BG has a 30 years power warranty; Seraphim SRP-705-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 SRP-710-BHC-BG and Seraphim SRP-705-BHC-BG bifacial panels?
Both Seraphim SRP-710-BHC-BG and Seraphim SRP-705-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.
