According to our database: **Canadian Solar CS6.2-66TB-605** has higher module efficiency (**22.40%** vs **22.20%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Canadian Solar CS6.2-66TB-600 and Canadian Solar CS6.2-66TB-605? **Canadian Solar CS6.2-66TB-600** has a module efficiency of **22.20%**, while **Canadian Solar CS6.2-66TB-605** is **22.40%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Canadian Solar CS6.2-66TB-600 use vs Canadian Solar CS6.2-66TB-605? **Canadian Solar CS6.2-66TB-600** uses **TOPCon** cells; **Canadian Solar CS6.2-66TB-605** 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 CS6.2-66TB-600 and Canadian Solar CS6.2-66TB-605? **Canadian Solar CS6.2-66TB-600** has a **30 years** power warranty; **Canadian Solar CS6.2-66TB-605** 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 CS6.2-66TB-600 and Canadian Solar CS6.2-66TB-605 bifacial panels? Both **Canadian Solar CS6.2-66TB-600** and **Canadian Solar CS6.2-66TB-605** 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 CS6.2-66TB-600 vs Canadian Solar CS6.2-66TB-630](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-630) - 6 differences, the largest is module efficiency - [Canadian Solar CS6.2-66TB-600 vs Canadian Solar CS6.2-66TB-625](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-625) - 6 differences, the largest is module efficiency - [Canadian Solar CS6.2-66TB-600 vs Canadian Solar CS6.2-66TB-620](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-620) - 3 differences, the largest is module efficiency - [Canadian Solar CS6.2-66TB-600 vs Canadian Solar CS6.2-66TB-615](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-615) - 3 differences, the largest is module efficiency - [Canadian Solar CS6.2-66TB-600 vs Canadian Solar CS6.2-66TB-610](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-610) - 3 differences, the largest is module efficiency - [Canadian Solar CS6.2-66TB-600 vs Canadian Solar CS7N-730TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs7n-730tb-ag) - 10 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-600/csi-solar-co-ltd-canadian-solar-cs6-2-66tb-605 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.
