According to our database: **Canadian Solar CS7N-730TB-AG** has higher module efficiency (**23.50%** vs **23.10%**); **Canadian Solar CS6.2-66HB-625** tolerates heat better (temp coeff **-0.240%/°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 Canadian Solar CS6.2-66HB-625 and Canadian Solar CS7N-730TB-AG? **Canadian Solar CS6.2-66HB-625** has a module efficiency of **23.10%**, while **Canadian Solar CS7N-730TB-AG** is **23.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Canadian Solar CS6.2-66HB-625 use vs Canadian Solar CS7N-730TB-AG? **Canadian Solar CS6.2-66HB-625** uses **HJT** cells; **Canadian Solar CS7N-730TB-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 CS6.2-66HB-625 and Canadian Solar CS7N-730TB-AG? **Canadian Solar CS6.2-66HB-625** has a **30 years** power warranty; **Canadian Solar CS7N-730TB-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 CS6.2-66HB-625 and Canadian Solar CS7N-730TB-AG bifacial panels? Both **Canadian Solar CS6.2-66HB-625** and **Canadian Solar CS7N-730TB-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 CS6.2-66HB-625 vs Canadian Solar CS6.2-66HB-645](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-625/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-645) - 3 differences, the largest is module efficiency - [Canadian Solar CS6.2-66HB-625 vs Canadian Solar CS6.2-66HB-640](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-625/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-640) - 3 differences, the largest is module efficiency - [Canadian Solar CS6.2-66HB-625 vs Canadian Solar CS6.2-66HB-635](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-625/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-635) - 3 differences, the largest is module efficiency - [Canadian Solar CS6.2-66HB-625 vs Canadian Solar CS6.2-66HB-630](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-625/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-630) - One difference: module efficiency - [Canadian Solar CS6.2-66HB-625 vs Canadian Solar CS6.2-66HB-620](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-625/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-620) - The same specification on paper - [Canadian Solar CS7N-730TB-AG vs Canadian Solar CS7N-725TB-AG](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs7n-730tb-ag/csi-solar-co-ltd-canadian-solar-cs7n-725tb-ag) - One difference: module efficiency --- Source: https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-66hb-625/csi-solar-co-ltd-canadian-solar-cs7n-730tb-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.
