According to our database: **Leapton LP210\*210-M-66-NB-**720 W**** has higher module efficiency (**23.18%** vs **22.86%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Leapton LP210\*210-M-66-NB-720W and Leapton LP210\*210-M-66-NH-710W? **Leapton LP210\*210-M-66-NB-**720 W**** has a module efficiency of **23.18%**, while **Leapton LP210\*210-M-66-NH-**710 W**** is **22.86%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Leapton LP210\*210-M-66-NB-720W use vs Leapton LP210\*210-M-66-NH-710W? **Leapton LP210\*210-M-66-NB-**720 W**** uses **TOPCon** cells; **Leapton LP210\*210-M-66-NH-**710 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 LP210\*210-M-66-NB-720W and Leapton LP210\*210-M-66-NH-710W? **Leapton LP210\*210-M-66-NB-**720 W**** has a **30 years** power warranty; **Leapton LP210\*210-M-66-NH-**710 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 LP210\*210-M-66-NB-720W and Leapton LP210\*210-M-66-NH-710W bifacial panels? **Leapton LP210\*210-M-66-NB-**720 W**** is bifacial (captures light from both faces); **Leapton LP210\*210-M-66-NH-**710 W**** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Leapton LP210\*210-M-66-NB-720W vs Leapton LP210\*210-M-66-NB-715W](https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nb-715w) - The same specification on paper - [Leapton LP210\*210-M-66-NB-720W vs Leapton LP210\*210-M-66-NB-710W](https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nb-710w) - 3 differences, the largest is module efficiency - [Leapton LP210\*210-M-66-NB-720W vs Leapton LP210\*210-M-66-NB-705W](https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nb-705w) - 3 differences, the largest is module efficiency - [Leapton LP210\*210-M-66-NB-720W vs Leapton LP210\*210-M-66-NB-700W](https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nb-700w) - 3 differences, the largest is module efficiency - [Leapton LP210\*210-M-66-NB-720W vs Leapton LP210\*210-M-66-NB-695W](https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nb-695w) - 5 differences, the largest is module efficiency - [Leapton LP210\*210-M-66-NB-720W vs Leapton LP210\*210-M-66-NB-690W](https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nb-690w) - 6 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/leapton-lp210-210-m-66-nb-720w/leapton-lp210-210-m-66-nh-710w 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.
