According to our database: **Sun Earth DXM8-54HBG-450** has higher module efficiency (**23.00%** vs **22.00%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sun Earth DXM8-54HBG-430 and Sun Earth DXM8-54HBG-450? **Sun Earth DXM8-54HBG-430** has a module efficiency of **22.00%**, while **Sun Earth DXM8-54HBG-450** is **23.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sun Earth DXM8-54HBG-430 use vs Sun Earth DXM8-54HBG-450? **Sun Earth DXM8-54HBG-430** uses **TOPCon** cells; **Sun Earth DXM8-54HBG-450** 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-430 and Sun Earth DXM8-54HBG-450? **Sun Earth DXM8-54HBG-430** has a **40 years** power warranty; **Sun Earth DXM8-54HBG-450** has a **40 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-430 and Sun Earth DXM8-54HBG-450 bifacial panels? Both **Sun Earth DXM8-54HBG-430** and **Sun Earth DXM8-54HBG-450** 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-430 vs Sun Earth DXM8-54HBG-455](https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-54hbg-455) - 6 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-430 vs Sun Earth DXM8-54HBG-440](https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-54hbg-440) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-430 vs Sun Earth DXM8-54HBG-435](https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-54hbg-435) - One difference: module efficiency - [Sun Earth DXM8-54HBG-430 vs Sun Earth DXM8-54HBG-420](https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-54hbg-420) - 3 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-430 vs Sun Earth DXM8-72HBG 610W](https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-72hbg-610w) - 13 differences, the largest is module efficiency - [Sun Earth DXM8-54HBG-430 vs Sun Earth DXM8-72H-610](https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-72h-610) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sun-earth-dxm8-54hbg-430/sun-earth-dxm8-54hbg-450 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.
