According to our database: **Canadian Solar CS7N-705TB-AG** has higher module efficiency (**22.70%** vs **22.50%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Canadian Solar CS7N-700TB-AG and Canadian Solar CS7N-705TB-AG? **Canadian Solar CS7N-700TB-AG** has a module efficiency of **22.50%**, while **Canadian Solar CS7N-705TB-AG** is **22.70%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Canadian Solar CS7N-700TB-AG use vs Canadian Solar CS7N-705TB-AG? **Canadian Solar CS7N-700TB-AG** uses **TOPCon** cells; **Canadian Solar CS7N-705TB-AG** 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 Canadian Solar CS7N-700TB-AG and Canadian Solar CS7N-705TB-AG? **Canadian Solar CS7N-700TB-AG** has a **30 years** power warranty; **Canadian Solar CS7N-705TB-AG** 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 Canadian Solar CS7N-700TB-AG and Canadian Solar CS7N-705TB-AG bifacial panels? Both **Canadian Solar CS7N-700TB-AG** and **Canadian Solar CS7N-705TB-AG** 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 - [Canadian Solar CS7N-700TB-AG vs Canadian Solar CS7N-730TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-730tb-ag) - 6 differences, the largest is module efficiency - [Canadian Solar CS7N-700TB-AG vs Canadian Solar CS7N-725TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-725tb-ag) - 5 differences, the largest is module efficiency - [Canadian Solar CS7N-700TB-AG vs Canadian Solar CS7N-720TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-720tb-ag) - 3 differences, the largest is module efficiency - [Canadian Solar CS7N-700TB-AG vs Canadian Solar CS7N-715TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-715tb-ag) - 3 differences, the largest is module efficiency - [Canadian Solar CS7N-700TB-AG vs Canadian Solar CS7N-710TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-710tb-ag) - 3 differences, the largest is module efficiency - [Canadian Solar CS7N-700TB-AG vs Canadian Solar CS7N-695TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-695tb-ag) - The same specification on paper --- Source: https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-700tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-705tb-ag 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.
