MY Solar MS720N-HJTGB vs AIKO AIKO-A785-GRH78Dw

Q: Which panel is better: MY Solar MS720N-HJTGB or AIKO AIKO-A785-GRH78Dw?

According to our database: AIKO AIKO-A785-GRH78Dw has higher module efficiency (24.40% vs 23.17%). 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 AIKO AIKO-A785-GRH78Dw?

MY Solar MS720N-HJTGB has a module efficiency of 23.17%, while AIKO AIKO-A785-GRH78Dw is 24.40%. 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 AIKO AIKO-A785-GRH78Dw?

MY Solar MS720N-HJTGB uses HJT cells; AIKO AIKO-A785-GRH78Dw uses Back Contact. 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 AIKO AIKO-A785-GRH78Dw?

MY Solar MS720N-HJTGB has a 30 years power warranty; AIKO AIKO-A785-GRH78Dw 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 AIKO AIKO-A785-GRH78Dw bifacial panels?

Both MY Solar MS720N-HJTGB and AIKO AIKO-A785-GRH78Dw 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.

Thirty years of production

A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.260 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
