According to our database: **IBC Solar YH**720 W**-33MHD/MH** has higher module efficiency (**23.18%** vs **23.17%**); **MY Solar MS720N-HJTGB** tolerates heat better (temp coeff **-0.260%/°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 YH720W-33MHD/MH and MY Solar MS720N-HJTGB? **IBC Solar YH**720 W**-33MHD/MH** has a module efficiency of **23.18%**, while **MY Solar MS720N-HJTGB** is **23.17%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does IBC Solar YH720W-33MHD/MH use vs MY Solar MS720N-HJTGB? **IBC Solar YH**720 W**-33MHD/MH** uses **TOPCon** cells; **MY Solar MS720N-HJTGB** uses **HJT**. 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 YH720W-33MHD/MH and MY Solar MS720N-HJTGB? **IBC Solar YH**720 W**-33MHD/MH** has a **30 years** power warranty; **MY Solar MS720N-HJTGB** 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 YH720W-33MHD/MH and MY Solar MS720N-HJTGB bifacial panels? Both **IBC Solar YH**720 W**-33MHD/MH** and **MY Solar MS720N-HJTGB** 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 - [IBC Solar YH720W-33MHD/MH vs IBC Solar YH715W-33MHD/MH](https://comparepv.com/compare/ibc-solar-yh720w-33mhd-mh/ibc-solar-yh715w-33mhd-mh) - The same specification on paper - [IBC Solar YH720W-33MHD/MH vs IBC Solar YH710W-33MHD/MH](https://comparepv.com/compare/ibc-solar-yh720w-33mhd-mh/ibc-solar-yh710w-33mhd-mh) - 3 differences, the largest is module efficiency - [MY Solar MS720N-HJTGB vs MY Solar MS740N-HJTGB](https://comparepv.com/compare/my-solar-ms720n-hjtgb/my-solar-ms740n-hjtgb) - 5 differences, the largest is module efficiency - [MY Solar MS720N-HJTGB vs MY Solar MS735N-HJTGB](https://comparepv.com/compare/my-solar-ms720n-hjtgb/my-solar-ms735n-hjtgb) - 4 differences, the largest is module efficiency - [MY Solar MS720N-HJTGB vs MY Solar MS730N-HJTGB](https://comparepv.com/compare/my-solar-ms720n-hjtgb/my-solar-ms730n-hjtgb) - 4 differences, the largest is temperature coefficient - [MY Solar MS720N-HJTGB vs MY Solar MS725N-HJTGB](https://comparepv.com/compare/my-solar-ms720n-hjtgb/my-solar-ms725n-hjtgb) - One difference: temperature coefficient --- Source: https://comparepv.com/compare/ibc-solar-yh720w-33mhd-mh/my-solar-ms720n-hjtgb 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.
