According to our database: **Sun Earth DXM8-72HBG **610 W**** has higher module efficiency (**23.60%** vs **23.00%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sun Earth DXM8-54HBG-450 and Sun Earth DXM8-72HBG 610W? **Sun Earth DXM8-54HBG-450** has a module efficiency of **23.00%**, while **Sun Earth DXM8-72HBG **610 W**** is **23.60%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sun Earth DXM8-54HBG-450 use vs Sun Earth DXM8-72HBG 610W? **Sun Earth DXM8-54HBG-450** uses **TOPCon** cells; **Sun Earth DXM8-72HBG **610 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 Sun Earth DXM8-54HBG-450 and Sun Earth DXM8-72HBG 610W? **Sun Earth DXM8-54HBG-450** has a **40 years** power warranty; **Sun Earth DXM8-72HBG **610 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 Sun Earth DXM8-54HBG-450 and Sun Earth DXM8-72HBG 610W bifacial panels? Both **Sun Earth DXM8-54HBG-450** and **Sun Earth DXM8-72HBG **610 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 - [Sun Earth DXM8-54HBG-450 vs Sun Earth DXM8-54HBG-455](https://comparepv.com/compare/sun-earth-dxm8-54hbg-450/sun-earth-dxm8-54hbg-455) - One difference: module efficiency - [Sun Earth DXM8-54HBG-450 vs Sun Earth DXM8-54HBG-440](https://comparepv.com/compare/sun-earth-dxm8-54hbg-450/sun-earth-dxm8-54hbg-440) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-450 vs Sun Earth DXM8-54HBG-435](https://comparepv.com/compare/sun-earth-dxm8-54hbg-450/sun-earth-dxm8-54hbg-435) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-450 vs Sun Earth DXM8-54HBG-430](https://comparepv.com/compare/sun-earth-dxm8-54hbg-450/sun-earth-dxm8-54hbg-430) - 4 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-450 vs Sun Earth DXM8-54HBG-420](https://comparepv.com/compare/sun-earth-dxm8-54hbg-450/sun-earth-dxm8-54hbg-420) - 7 differences, the largest is module efficiency - [Sun Earth DXM8-72HBG 610W vs Sun Earth DXM8-72HBG 600W](https://comparepv.com/compare/sun-earth-dxm8-72hbg-610w/sun-earth-dxm8-72hbg-600w) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sun-earth-dxm8-54hbg-450/sun-earth-dxm8-72hbg-610w 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.
