According to our database: **DAH Solar DHM-60X10/FS(BW)-460** has higher module efficiency (**21.32%** vs **21.08%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of DAH Solar DHM-60X10/FS(BW)-455W and DAH Solar DHM-60X10/FS(BW)-460? **DAH Solar DHM-60X10/FS(BW)-**455 W**** has a module efficiency of **21.08%**, while **DAH Solar DHM-60X10/FS(BW)-460** is **21.32%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does DAH Solar DHM-60X10/FS(BW)-455W use vs DAH Solar DHM-60X10/FS(BW)-460? **DAH Solar DHM-60X10/FS(BW)-**455 W**** uses **PERC** cells; **DAH Solar DHM-60X10/FS(BW)-460** 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 DAH Solar DHM-60X10/FS(BW)-455W and DAH Solar DHM-60X10/FS(BW)-460? **DAH Solar DHM-60X10/FS(BW)-**455 W**** has a **25 years** power warranty; **DAH Solar DHM-60X10/FS(BW)-460** has a **25 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. ## Related comparisons - [DAH Solar DHM-60X10/FS(BW)-455W vs DAH Solar DHM-60X10/FS(BW)-460W](https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-460w) - One difference: module efficiency - [DAH Solar DHM-60X10/FS(BW)-455W vs DAH Solar DHM-60X10/FS(BW)-455](https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-455) - The same specification on paper - [DAH Solar DHM-60X10/FS(BW)-455W vs DAH Solar DHM-60X10/FS(BW)-450W](https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-450w) - One difference: module efficiency - [DAH Solar DHM-60X10/FS(BW)-455W vs DAH Solar DHM-60X10/FS(BW)-450](https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-450) - One difference: module efficiency - [DAH Solar DHM-60X10/FS(BW)-455W vs DAH Solar DHM-60X10/FS(BW)-445W](https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-445w) - 3 differences, the largest is module efficiency - [DAH Solar DHM-60X10/FS(BW)-455W vs DAH Solar DHM-60X10/FS(BW)-445](https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-445) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/dah-dhm-60x10-fs-bw-455w/dah-dhm-60x10-fs-bw-460 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.
