MY Solar MS720N-HJTGB vs MY Solar MS705N-HJTGB

Q: Which panel is better: MY Solar MS720N-HJTGB or MY Solar MS705N-HJTGB?

According to our database: MY Solar MS720N-HJTGB has higher module efficiency (23.17% vs 22.69%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of MY Solar MS720N-HJTGB and MY Solar MS705N-HJTGB?

MY Solar MS720N-HJTGB has a module efficiency of 23.17%, while MY Solar MS705N-HJTGB is 22.69%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does MY Solar MS720N-HJTGB use vs MY Solar MS705N-HJTGB?

MY Solar MS720N-HJTGB uses HJT cells; MY Solar MS705N-HJTGB uses HJT. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on MY Solar MS720N-HJTGB and MY Solar MS705N-HJTGB?

MY Solar MS720N-HJTGB has a 30 years power warranty; MY Solar MS705N-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.

Q: Are MY Solar MS720N-HJTGB and MY Solar MS705N-HJTGB bifacial panels?

Both MY Solar MS720N-HJTGB and MY Solar MS705N-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.
