According to our database: **Leapton LP182\*210-M-54-NB-**510 W**** has higher module efficiency (**22.93%** vs **22.48%**). 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-500W and Leapton LP182\*210-M-54-NB-510W? **Leapton LP182\*210-M-54-NB-**500 W**** has a module efficiency of **22.48%**, while **Leapton LP182\*210-M-54-NB-**510 W**** is **22.93%**. 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-500W use vs Leapton LP182\*210-M-54-NB-510W? **Leapton LP182\*210-M-54-NB-**500 W**** uses **TOPCon** cells; **Leapton LP182\*210-M-54-NB-**510 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-500W and Leapton LP182\*210-M-54-NB-510W? **Leapton LP182\*210-M-54-NB-**500 W**** has a **30 years** power warranty; **Leapton LP182\*210-M-54-NB-**510 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-500W and Leapton LP182\*210-M-54-NB-510W bifacial panels? Both **Leapton LP182\*210-M-54-NB-**500 W**** and **Leapton LP182\*210-M-54-NB-**510 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. ## Related comparisons - [Leapton LP182\*210-M-54-NB-500W vs Leapton LP182\*210-M-54-NB-505W](https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp182-210-m-54-nb-505w) - One difference: module efficiency - [Leapton LP182\*210-M-54-NB-500W vs Leapton LP182\*210-M-54-NB-495W](https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp182-210-m-54-nb-495w) - One difference: module efficiency - [Leapton LP182\*210-M-54-NB-500W vs Leapton LP182\*210-M-54-NB-490W](https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp182-210-m-54-nb-490w) - 3 differences, the largest is module efficiency - [Leapton LP182\*210-M-54-NB-500W vs Leapton LP210\*210-M-66-NH-720W](https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp210-210-m-66-nh-720w) - 13 differences, the largest is module efficiency - [Leapton LP182\*210-M-54-NB-500W vs Leapton LP210\*210-M-66-NB-720W](https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp210-210-m-66-nb-720w) - 12 differences, the largest is module efficiency - [Leapton LP182\*210-M-54-NB-500W vs Leapton LP210\*210-M-66-NH-715W](https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp210-210-m-66-nh-715w) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/leapton-lp182-210-m-54-nb-500w/leapton-lp182-210-m-54-nb-510w Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
