According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sun Earth DXM8-72H-580 and Sun Earth DXM8-72HBG 580W? **Sun Earth DXM8-72H-580** has a module efficiency of **22.50%**, while **Sun Earth DXM8-72HBG **580 W**** is **22.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sun Earth DXM8-72H-580 use vs Sun Earth DXM8-72HBG 580W? **Sun Earth DXM8-72H-580** uses **TOPCon** cells; **Sun Earth DXM8-72HBG **580 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 DXM8-72H-580 and Sun Earth DXM8-72HBG 580W? **Sun Earth DXM8-72H-580** has a **30 years** power warranty; **Sun Earth DXM8-72HBG **580 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 DXM8-72H-580 and Sun Earth DXM8-72HBG 580W bifacial panels? Both **Sun Earth DXM8-72H-580** and **Sun Earth DXM8-72HBG **580 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 DXM8-72H-580 vs Sun Earth DXM8-72HBG 610W](https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72hbg-610w) - 7 differences, the largest is module efficiency - [Sun Earth DXM8-72H-580 vs Sun Earth DXM8-72H-610](https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72h-610) - 6 differences, the largest is module efficiency - [Sun Earth DXM8-72H-580 vs Sun Earth DXM8-72HBG 600W](https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72hbg-600w) - 5 differences, the largest is module efficiency - [Sun Earth DXM8-72H-580 vs Sun Earth DXM8-72H-600](https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72h-600) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-72H-580 vs Sun Earth DXM8-72HBG 590W](https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72hbg-590w) - 5 differences, the largest is weight - [Sun Earth DXM8-72H-580 vs Sun Earth DXM8-72H-590](https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72h-590) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sun-earth-dxm8-72h-580/sun-earth-dxm8-72hbg-580w 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.
