According to our database: **JA Solar JAM54D40-465/LB** has higher module efficiency (**23.30%** vs **23.00%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Canadian Solar CS6.2-48TD-460 and JA Solar JAM54D40-465/LB? **Canadian Solar CS6.2-48TD-460** has a module efficiency of **23.00%**, while **JA Solar JAM54D40-465/LB** is **23.30%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Canadian Solar CS6.2-48TD-460 use vs JA Solar JAM54D40-465/LB? **Canadian Solar CS6.2-48TD-460** uses **TOPCon** cells; **JA Solar JAM54D40-465/LB** 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 CS6.2-48TD-460 and JA Solar JAM54D40-465/LB? **Canadian Solar CS6.2-48TD-460** has a **30 years** power warranty; **JA Solar JAM54D40-465/LB** 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 CS6.2-48TD-460 and JA Solar JAM54D40-465/LB bifacial panels? Both **Canadian Solar CS6.2-48TD-460** and **JA Solar JAM54D40-465/LB** 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 CS6.2-48TD-460 vs Canadian Solar CS6.2-66TM-635](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/csi-solar-co-ltd-canadian-solar-cs6-2-66tm-635) - 14 differences, the largest is rated power - [Canadian Solar CS6.2-48TD-460 vs Canadian Solar CS6.2-66TM-630](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/csi-solar-co-ltd-canadian-solar-cs6-2-66tm-630) - 14 differences, the largest is rated power - [Canadian Solar CS6.2-48TD-460 vs Canadian Solar CS6.2-66TM-625](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/csi-solar-co-ltd-canadian-solar-cs6-2-66tm-625) - 12 differences, the largest is rated power - [Canadian Solar CS6.2-48TD-460 vs Canadian Solar CS6.2-66TM-620](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/csi-solar-co-ltd-canadian-solar-cs6-2-66tm-620) - 12 differences, the largest is rated power - [Canadian Solar CS6.2-48TD-460 vs Canadian Solar CS6.2-66TM-615](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/csi-solar-co-ltd-canadian-solar-cs6-2-66tm-615) - 13 differences, the largest is rated power - [Canadian Solar CS6.2-48TD-460 vs Canadian Solar CS6.2-66TM-610](https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/csi-solar-co-ltd-canadian-solar-cs6-2-66tm-610) - 14 differences, the largest is rated power --- Source: https://comparepv.com/compare/csi-solar-co-ltd-canadian-solar-cs6-2-48td-460/ja-solar-jam54d40-465-lb 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.
