According to our database: **DMEGC DM460M10RT-B54HBW** has higher module efficiency (**23.00%** vs **22.50%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of DMEGC DM450M10RT-B54HBB and DMEGC DM460M10RT-B54HBW? **DMEGC DM450M10RT-B54HBB** has a module efficiency of **22.50%**, while **DMEGC DM460M10RT-B54HBW** is **23.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does DMEGC DM450M10RT-B54HBB use vs DMEGC DM460M10RT-B54HBW? **DMEGC DM450M10RT-B54HBB** uses **TOPCon** cells; **DMEGC DM460M10RT-B54HBW** 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 DMEGC DM450M10RT-B54HBB and DMEGC DM460M10RT-B54HBW? **DMEGC DM450M10RT-B54HBB** has a **30 years** power warranty; **DMEGC DM460M10RT-B54HBW** 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 DMEGC DM450M10RT-B54HBB and DMEGC DM460M10RT-B54HBW bifacial panels? Both **DMEGC DM450M10RT-B54HBB** and **DMEGC DM460M10RT-B54HBW** 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 - [DMEGC DM450M10RT-B54HBB vs DMEGC DM465M10RT-B54HBW](https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-solar-hengdian-group-dm465m10rt-b54hbw) - 3 differences, the largest is module efficiency - [DMEGC DM450M10RT-B54HBB vs DMEGC DM460M10RT-B54HBB](https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-hengdian-group-dm460m10rt-b54hbb) - 3 differences, the largest is module efficiency - [DMEGC DM450M10RT-B54HBB vs DMEGC DM460M10RT-B54HBT](https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-solar-hengdian-group-dmegc-magnetics-co-ltd-dm460m10rt-b54hbt) - 3 differences, the largest is module efficiency - [DMEGC DM450M10RT-B54HBB vs DMEGC DM455M10RT-B54HBB](https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-hengdian-group-dm455m10rt-b54hbb) - One difference: module efficiency - [DMEGC DM450M10RT-B54HBB vs DMEGC DM455M10RT-B54HBW](https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-solar-hengdian-group-dm455m10rt-b54hbw) - One difference: module efficiency - [DMEGC DM450M10RT-B54HBB vs DMEGC DM455M10RT-B54HBT](https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-solar-hengdian-group-dmegc-magnetics-co-ltd-dm455m10rt-b54hbt) - One difference: module efficiency --- Source: https://comparepv.com/compare/dmegc-hengdian-group-dm450m10rt-b54hbb/dmegc-solar-hengdian-group-dm460m10rt-b54hbw 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.
