Leapton LP182182-M-54-NB-450W vs Leapton LP182210-M-54-NB-500W

Q: Which panel is better: Leapton LP182*182-M-54-NB-450W or Leapton LP182*210-M-54-NB-500W?

According to our database: Leapton LP182*182-M-54-NB-450W has higher module efficiency (22.52% vs 22.48%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Leapton LP182*182-M-54-NB-450W and Leapton LP182*210-M-54-NB-500W?

Leapton LP182*182-M-54-NB-450W has a module efficiency of 22.52%, while Leapton LP182*210-M-54-NB-500W is 22.48%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Leapton LP182*182-M-54-NB-450W use vs Leapton LP182*210-M-54-NB-500W?

Leapton LP182*182-M-54-NB-450W uses TOPCon cells; Leapton LP182*210-M-54-NB-500W 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 LP182*182-M-54-NB-450W and Leapton LP182*210-M-54-NB-500W?

Leapton LP182*182-M-54-NB-450W has a 30 years power warranty; Leapton LP182*210-M-54-NB-500W 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 LP182*182-M-54-NB-450W and Leapton LP182*210-M-54-NB-500W bifacial panels?

Both Leapton LP182*182-M-54-NB-450W and Leapton LP182*210-M-54-NB-500W 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.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, 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.
