According to our database: **Leapton LP210\*210-M-66-NH-**715 W**** has higher module efficiency (**23.12%** vs **22.83%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Leapton LP182\*199-M-66-NB 590W and Leapton LP210\*210-M-66-NH-715W? **Leapton LP182\*199-M-66-NB **590 W**** has a module efficiency of **22.83%**, 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 LP182\*199-M-66-NB 590W use vs Leapton LP210\*210-M-66-NH-715W? **Leapton LP182\*199-M-66-NB **590 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 LP182\*199-M-66-NB 590W and Leapton LP210\*210-M-66-NH-715W? **Leapton LP182\*199-M-66-NB **590 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 LP182\*199-M-66-NB 590W and Leapton LP210\*210-M-66-NH-715W bifacial panels? **Leapton LP182\*199-M-66-NB **590 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. ## Related comparisons - [Leapton LP182\*199-M-66-NB 590W vs Leapton LP182\*199-M-66-NB 585W](https://comparepv.com/compare/leapton-lp182-199-m-66-nb-590w/leapton-lp182-199-m-66-nb-585w) - The same specification on paper - [Leapton LP182\*199-M-66-NB 590W vs Leapton LP182\*199-M-66-NB 580W](https://comparepv.com/compare/leapton-lp182-199-m-66-nb-590w/leapton-lp182-199-m-66-nb-580w) - 3 differences, the largest is module efficiency - [Leapton LP182\*199-M-66-NB 590W vs Leapton LP182\*199-M-66-NB 575W](https://comparepv.com/compare/leapton-lp182-199-m-66-nb-590w/leapton-lp182-199-m-66-nb-575w) - 3 differences, the largest is module efficiency - [Leapton LP182\*199-M-66-NB 590W vs Leapton LP182\*199-M-66-NB 570W](https://comparepv.com/compare/leapton-lp182-199-m-66-nb-590w/leapton-lp182-199-m-66-nb-570w) - 3 differences, the largest is module efficiency - [Leapton LP210\*210-M-66-NH-715W vs Leapton LP210\*210-M-66-NH-720W](https://comparepv.com/compare/leapton-lp210-210-m-66-nh-715w/leapton-lp210-210-m-66-nh-720w) - The same specification on paper - [Leapton LP210\*210-M-66-NH-715W vs Leapton LP210\*210-M-66-NH-710W](https://comparepv.com/compare/leapton-lp210-210-m-66-nh-715w/leapton-lp210-210-m-66-nh-710w) - One difference: module efficiency --- Source: https://comparepv.com/compare/leapton-lp182-199-m-66-nb-590w/leapton-lp210-210-m-66-nh-715w 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.
