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 (-0.300 %/°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: Leapton LP210*210-M-66-NB-720W or Leapton LP210*210-M-66-NH-715W?
According to our database: Leapton LP210*210-M-66-NB-720 W has higher module efficiency (23.18% vs 23.12%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Leapton LP210*210-M-66-NB-720W and Leapton LP210*210-M-66-NH-715W?
Leapton LP210*210-M-66-NB-720 W has a module efficiency of 23.18%, while Leapton LP210*210-M-66-NH-715 W is 23.12%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Leapton LP210*210-M-66-NB-720W use vs Leapton LP210*210-M-66-NH-715W?
Leapton LP210*210-M-66-NB-720 W uses TOPCon cells; Leapton LP210*210-M-66-NH-715 W 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 Leapton LP210*210-M-66-NB-720W and Leapton LP210*210-M-66-NH-715W?
Leapton LP210*210-M-66-NB-720 W has a 30 years power warranty; Leapton LP210*210-M-66-NH-715 W 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 Leapton LP210*210-M-66-NB-720W and Leapton LP210*210-M-66-NH-715W bifacial panels?
Leapton LP210*210-M-66-NB-720 W is bifacial (captures light from both faces); Leapton LP210*210-M-66-NH-715 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
