According to our database: **DAS Solar DAS-DH120NA-485** has higher module efficiency (**22.50%** vs **22.10%**); **DAS Solar DAS-DH120ND-**500 W**** tolerates heat better (temp coeff **-0.280%/°C** vs **-0.300%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W? **DAS Solar DAS-DH120NA-485** has a module efficiency of **22.50%**, while **DAS Solar DAS-DH120ND-**500 W**** is **22.10%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does DAS Solar DAS-DH120NA-485 use vs DAS Solar DAS-DH120ND-500W? **DAS Solar DAS-DH120NA-485** uses **TOPCon** cells; **DAS Solar DAS-DH120ND-**500 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 DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W? **DAS Solar DAS-DH120NA-485** has a **30 years** power warranty; **DAS Solar DAS-DH120ND-**500 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 DAS Solar DAS-DH120NA-485 and DAS Solar DAS-DH120ND-500W bifacial panels? Both **DAS Solar DAS-DH120NA-485** and **DAS Solar DAS-DH120ND-**500 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 - [DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120ND-515W](https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120nd-515w) - 9 differences, the largest is rated power - [DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120ND-510W](https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120nd-510w) - 7 differences, the largest is rated power - [DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120ND-505W](https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120nd-505w) - 8 differences, the largest is temperature coefficient - [DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120ND-495W](https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120nd-495w) - 10 differences, the largest is module efficiency - [DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120NA-490](https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120na-490) - One difference: module efficiency - [DAS Solar DAS-DH120NA-485 vs DAS Solar DAS-DH120ND-490W](https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120nd-490w) - 10 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/das-solar-das-dh120na-485/das-solar-das-dh120nd-500w 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.
