Questions about this pairing

Which panel is better: Peimar SG330P or Peimar OR10H450MNDB (FB)?
According to our database: Peimar OR10H450MNDB (FB) has higher module efficiency (23.04% vs 17.00%); Peimar OR10H450MNDB (FB) tolerates heat better (temp coeff -0.290%/°C vs -0.430%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Peimar SG330P and Peimar OR10H450MNDB (FB)?
Peimar SG330P has a module efficiency of 17.00%, while Peimar OR10H450MNDB (FB) is 23.04%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Peimar SG330P use vs Peimar OR10H450MNDB (FB)?
Peimar SG330P uses PERC cells; Peimar OR10H450MNDB (FB) 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 Peimar SG330P and Peimar OR10H450MNDB (FB)?
Peimar SG330P has a 30 years power warranty; Peimar OR10H450MNDB (FB) 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 Peimar SG330P and Peimar OR10H450MNDB (FB) bifacial panels?
Peimar OR10H450MNDB (FB) is bifacial (captures light from both faces); Peimar SG330P is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
