Questions about this pairing

Which panel is better: Peimar OR10H450MNDB (FB) or AIKO AIKO-A495-MCE54Mw?
According to our database: AIKO AIKO-A495-MCE54Mw has higher module efficiency (24.80% vs 23.04%); AIKO AIKO-A495-MCE54Mw tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Peimar OR10H450MNDB (FB) and AIKO AIKO-A495-MCE54Mw?
Peimar OR10H450MNDB (FB) has a module efficiency of 23.04%, while AIKO AIKO-A495-MCE54Mw is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Peimar OR10H450MNDB (FB) use vs AIKO AIKO-A495-MCE54Mw?
Peimar OR10H450MNDB (FB) uses TOPCon cells; AIKO AIKO-A495-MCE54Mw uses Back Contact. 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 OR10H450MNDB (FB) and AIKO AIKO-A495-MCE54Mw?
Peimar OR10H450MNDB (FB) has a 30 years power warranty; AIKO AIKO-A495-MCE54Mw 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 OR10H450MNDB (FB) and AIKO AIKO-A495-MCE54Mw bifacial panels?
Peimar OR10H450MNDB (FB) is bifacial (captures light from both faces); AIKO AIKO-A495-MCE54Mw is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
