Leapton LP210210-M-66-NH-705W vs Leapton LP210210-M-66-NB-720W

Q: Which panel is better: Leapton LP210*210-M-66-NH-705W or Leapton LP210*210-M-66-NB-720W?

According to our database: Leapton LP210*210-M-66-NB-720W has higher module efficiency (23.18% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Leapton LP210*210-M-66-NH-705W and Leapton LP210*210-M-66-NB-720W?

Leapton LP210*210-M-66-NH-705W has a module efficiency of 22.70%, while Leapton LP210*210-M-66-NB-720W is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Leapton LP210*210-M-66-NH-705W use vs Leapton LP210*210-M-66-NB-720W?

Leapton LP210*210-M-66-NH-705W uses TOPCon cells; Leapton LP210*210-M-66-NB-720W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Leapton LP210*210-M-66-NH-705W and Leapton LP210*210-M-66-NB-720W?

Leapton LP210*210-M-66-NH-705W has a 30 years power warranty; Leapton LP210*210-M-66-NB-720W 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.

Q: Are Leapton LP210*210-M-66-NH-705W and Leapton LP210*210-M-66-NB-720W bifacial panels?

Leapton LP210*210-M-66-NB-720W is bifacial (captures light from both faces); Leapton LP210*210-M-66-NH-705W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

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

Cell temperature

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.
