What it means on a roof

Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°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: Peimar OR10H595MNDB or Peimar OR10H450MNDB (FB)?
According to our database: Peimar OR10H450MNDB (FB) has higher module efficiency (23.04% vs 23.03%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Peimar OR10H595MNDB and Peimar OR10H450MNDB (FB)?
Peimar OR10H595MNDB has a module efficiency of 23.03%, 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 OR10H595MNDB use vs Peimar OR10H450MNDB (FB)?
Peimar OR10H595MNDB uses TOPCon 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 OR10H595MNDB and Peimar OR10H450MNDB (FB)?
Peimar OR10H595MNDB 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 OR10H595MNDB and Peimar OR10H450MNDB (FB) bifacial panels?
Both Peimar OR10H595MNDB and Peimar OR10H450MNDB (FB) 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.
