What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, 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 LP182*210-M-54-NB-510W or Leapton LP182*182-M-54-NB-440W?
According to our database: Leapton LP182*210-M-54-NB-510 W has higher module efficiency (22.93% vs 22.02%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Leapton LP182*210-M-54-NB-510W and Leapton LP182*182-M-54-NB-440W?
Leapton LP182*210-M-54-NB-510 W has a module efficiency of 22.93%, while Leapton LP182*182-M-54-NB-440 W is 22.02%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Leapton LP182*210-M-54-NB-510W use vs Leapton LP182*182-M-54-NB-440W?
Leapton LP182*210-M-54-NB-510 W uses TOPCon cells; Leapton LP182*182-M-54-NB-440 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 LP182*210-M-54-NB-510W and Leapton LP182*182-M-54-NB-440W?
Leapton LP182*210-M-54-NB-510 W has a 30 years power warranty; Leapton LP182*182-M-54-NB-440 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 LP182*210-M-54-NB-510W and Leapton LP182*182-M-54-NB-440W bifacial panels?
Both Leapton LP182*210-M-54-NB-510 W and Leapton LP182*182-M-54-NB-440 W 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.
