According to our database: **IBC Solar YH**720 W**-33MHD/MH** has higher module efficiency (**23.18%** vs **22.77%**); **IBC Solar White 455 MS-TA1** tolerates heat better (temp coeff **-0.300%/°C** vs **-0.350%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of IBC Solar White 455 MS-TA1 and IBC Solar YH720W-33MHD/MH? **IBC Solar White 455 MS-TA1** has a module efficiency of **22.77%**, while **IBC Solar YH**720 W**-33MHD/MH** is **23.18%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does IBC Solar White 455 MS-TA1 use vs IBC Solar YH720W-33MHD/MH? **IBC Solar White 455 MS-TA1** uses **Back Contact** cells; **IBC Solar YH**720 W**-33MHD/MH** 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 IBC Solar White 455 MS-TA1 and IBC Solar YH720W-33MHD/MH? **IBC Solar White 455 MS-TA1** has a **30 years** power warranty; **IBC Solar YH**720 W**-33MHD/MH** 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 IBC Solar White 455 MS-TA1 and IBC Solar YH720W-33MHD/MH bifacial panels? **IBC Solar YH**720 W**-33MHD/MH** is bifacial (captures light from both faces); **IBC Solar White 455 MS-TA1** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [IBC Solar White 455 MS-TA1 vs IBC Solar IBC Module White 455 MS-TA1](https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-ibc-module-white-455-ms-ta1) - One difference: cell technology - [IBC Solar White 455 MS-TA1 vs IBC Solar IBC Module White 450 MS-TA1](https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-ibc-module-white-450-ms-ta1) - 2 differences, the largest is module efficiency - [IBC Solar White 455 MS-TA1 vs IBC Solar White 450 MS-TA1](https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-white-450-ms-ta1) - One difference: module efficiency - [IBC Solar White 455 MS-TA1 vs IBC Solar IBC Module White 445 MS-TA1](https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-ibc-module-white-445-ms-ta1) - 4 differences, the largest is module efficiency - [IBC Solar White 455 MS-TA1 vs IBC Solar White 445 MS-TA1](https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-white-445-ms-ta1) - 3 differences, the largest is module efficiency - [IBC Solar White 455 MS-TA1 vs IBC Solar IBC Module White 440 MS-TA1](https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-ibc-module-white-440-ms-ta1) - 4 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ibc-solar-white-455-ms-ta1/ibc-solar-yh720w-33mhd-mh 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.
