According to our database: **Sun Earth DXM8-60HBG **490 W**** has higher module efficiency (**22.60%** vs **21.70%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sun Earth DXM8-60HBG 470W and Sun Earth DXM8-60HBG 490W? **Sun Earth DXM8-60HBG **470 W**** has a module efficiency of **21.70%**, while **Sun Earth DXM8-60HBG **490 W**** is **22.60%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sun Earth DXM8-60HBG 470W use vs Sun Earth DXM8-60HBG 490W? **Sun Earth DXM8-60HBG **470 W**** uses **TOPCon** cells; **Sun Earth DXM8-60HBG **490 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 DXM8-60HBG 470W and Sun Earth DXM8-60HBG 490W? **Sun Earth DXM8-60HBG **470 W**** has a **30 years** power warranty; **Sun Earth DXM8-60HBG **490 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 DXM8-60HBG 470W and Sun Earth DXM8-60HBG 490W bifacial panels? Both **Sun Earth DXM8-60HBG **470 W**** and **Sun Earth DXM8-60HBG **490 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 DXM8-60HBG 470W vs Sun Earth DXM8-60HBG 505W](https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-60hbg-505w) - 7 differences, the largest is module efficiency - [Sun Earth DXM8-60HBG 470W vs Sun Earth DXM8-60HBG 500W](https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-60hbg-500w) - 6 differences, the largest is module efficiency - [Sun Earth DXM8-60HBG 470W vs Sun Earth DXM8-60HBG 480W](https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-60hbg-480w) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-60HBG 470W vs Sun Earth DXM8-60HBG 460W](https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-60hbg-460w) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-60HBG 470W vs Sun Earth DXM8-72HBG 610W](https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-72hbg-610w) - 12 differences, the largest is module efficiency - [Sun Earth DXM8-60HBG 470W vs Sun Earth DXM8-72H-610](https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-72h-610) - 11 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sun-earth-dxm8-60hbg-470w/sun-earth-dxm8-60hbg-490w 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.
