According to our database: **DAH Solar DHN-66Y18/DG-720** has higher module efficiency (**23.18%** vs **22.40%**); **DAH Solar DAS-DH132NC-695** tolerates heat better (temp coeff **-0.280%/°C** vs **-0.290%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of DAH Solar DHN-66Y18/DG-720 and DAH Solar DAS-DH132NC-695? **DAH Solar DHN-66Y18/DG-720** has a module efficiency of **23.18%**, while **DAH Solar DAS-DH132NC-695** is **22.40%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does DAH Solar DHN-66Y18/DG-720 use vs DAH Solar DAS-DH132NC-695? **DAH Solar DHN-66Y18/DG-720** uses **TOPCon** cells; **DAH Solar DAS-DH132NC-695** 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 DAH Solar DHN-66Y18/DG-720 and DAH Solar DAS-DH132NC-695? **DAH Solar DHN-66Y18/DG-720** has a **30 years** power warranty; **DAH Solar DAS-DH132NC-695** 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 DAH Solar DHN-66Y18/DG-720 and DAH Solar DAS-DH132NC-695 bifacial panels? Both **DAH Solar DHN-66Y18/DG-720** and **DAH Solar DAS-DH132NC-695** 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 - [DAH Solar DHN-66Y18/DG-720 vs DAH Solar DHN-66Y18/DG-725](https://comparepv.com/compare/dah-dhn-66y18-dg-720/dah-dhn-66y18-dg-725) - The same specification on paper - [DAH Solar DHN-66Y18/DG-720 vs DAH Solar DHN-66Y18/DG-715](https://comparepv.com/compare/dah-dhn-66y18-dg-720/dah-dhn-66y18-dg-715) - The same specification on paper - [DAH Solar DHN-66Y18/DG-720 vs DAH Solar DHN-66Y18/DG-710](https://comparepv.com/compare/dah-dhn-66y18-dg-720/dah-dhn-66y18-dg-710) - 3 differences, the largest is module efficiency - [DAH Solar DHN-66Y18/DG-720 vs DAH Solar DHN-66Y18/DG-705](https://comparepv.com/compare/dah-dhn-66y18-dg-720/dah-dhn-66y18-dg-705) - 3 differences, the largest is module efficiency - [DAH Solar DHN-66Y18/DG-720 vs DAH Solar DHN-66Y18/DG-700](https://comparepv.com/compare/dah-dhn-66y18-dg-720/dah-dhn-66y18-dg-700) - 3 differences, the largest is module efficiency - [DAH Solar DAS-DH132NC-695 vs DAH Solar DAS-DH132NC-715](https://comparepv.com/compare/dah-solar-das-dh132nc-695/dah-solar-das-dh132nc-715) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/dah-dhn-66y18-dg-720/dah-solar-das-dh132nc-695 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.
