According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of MY Solar MS720N-HJTGB and Mysolar USA MS720N-HJTGB? **MY Solar MS720N-HJTGB** has a module efficiency of **23.17%**, while **Mysolar USA MS720N-HJTGB** is **23.17%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does MY Solar MS720N-HJTGB use vs Mysolar USA MS720N-HJTGB? **MY Solar MS720N-HJTGB** uses **HJT** cells; **Mysolar USA 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 MY Solar MS720N-HJTGB and Mysolar USA MS720N-HJTGB? **MY Solar MS720N-HJTGB** has a **30 years** power warranty; **Mysolar USA 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 MY Solar MS720N-HJTGB and Mysolar USA MS720N-HJTGB bifacial panels? Both **MY Solar MS720N-HJTGB** and **Mysolar USA 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 - [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 - [MY Solar MS720N-HJTGB vs MY Solar MS715N-HJTGB](https://comparepv.com/compare/my-solar-ms720n-hjtgb/my-solar-ms715n-hjtgb) - The same specification on paper - [MY Solar MS720N-HJTGB vs MY Solar MS710N-HJTGB](https://comparepv.com/compare/my-solar-ms720n-hjtgb/my-solar-ms710n-hjtgb) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/my-solar-ms720n-hjtgb/mysolar-usa-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.
