According to our database: **Aptos Solar DNA-120-MF10-**455 W**** has higher module efficiency (**21.03%** vs **20.90%**); **Aptos Solar DNA-144-BF10-**540 W**-DG** tolerates heat better (temp coeff **-0.335%/°C** vs **-0.350%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Aptos Solar DNA-120-MF10-455W and Aptos Solar DNA-144-BF10-540W-DG? **Aptos Solar DNA-120-MF10-**455 W**** has a module efficiency of **21.03%**, while **Aptos Solar DNA-144-BF10-**540 W**-DG** is **20.90%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Aptos Solar DNA-120-MF10-455W use vs Aptos Solar DNA-144-BF10-540W-DG? **Aptos Solar DNA-120-MF10-**455 W**** uses **PERC** cells; **Aptos Solar DNA-144-BF10-**540 W**-DG** uses **PERC**. 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 Aptos Solar DNA-120-MF10-455W and Aptos Solar DNA-144-BF10-540W-DG? **Aptos Solar DNA-120-MF10-**455 W**** has a **30 years** power warranty; **Aptos Solar DNA-144-BF10-**540 W**-DG** 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 Aptos Solar DNA-120-MF10-455W and Aptos Solar DNA-144-BF10-540W-DG bifacial panels? **Aptos Solar DNA-144-BF10-**540 W**-DG** is bifacial (captures light from both faces); **Aptos Solar DNA-120-MF10-**455 W**** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Aptos Solar DNA-120-MF10-455W vs Aptos Solar DNA-120-MF10-460W](https://comparepv.com/compare/aptos-solar-dna-120-mf10-455w/aptos-solar-dna-120-mf10-460w) - One difference: module efficiency - [Aptos Solar DNA-120-MF10-455W vs Aptos Solar DNA-120-MF10-450W](https://comparepv.com/compare/aptos-solar-dna-120-mf10-455w/aptos-solar-dna-120-mf10-450w) - One difference: module efficiency - [Aptos Solar DNA-120-MF10-455W vs Aptos Solar DNA-120-MF10-445W](https://comparepv.com/compare/aptos-solar-dna-120-mf10-455w/aptos-solar-dna-120-mf10-445w) - 3 differences, the largest is module efficiency - [Aptos Solar DNA-144-BF10-540W-DG vs Aptos Solar DNA-144-BF10-550W-DG](https://comparepv.com/compare/aptos-solar-dna-144-bf10-540w-dg/aptos-solar-dna-144-bf10-550w-dg) - 3 differences, the largest is module efficiency - [Aptos Solar DNA-144-BF10-540W-DG vs Aptos Solar DNA-144-BF10-545W-DG](https://comparepv.com/compare/aptos-solar-dna-144-bf10-540w-dg/aptos-solar-dna-144-bf10-545w-dg) - The same specification on paper - [Aptos Solar DNA-120-MF10-455W vs Aptos Solar DNA-120-BF10-460W](https://comparepv.com/compare/aptos-solar-dna-120-mf10-455w/aptos-solar-dna-120-bf10-460w) - 4 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/aptos-solar-dna-120-mf10-455w/aptos-solar-dna-144-bf10-540w-dg 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.
