Questions about this pairing
Which panel is better: MY Solar MS730N-HJTGB or AIKO AIKO-A805-GRH78Dw?
According to our database: AIKO AIKO-A805-GRH78Dw has higher module efficiency (25.10% vs 23.50%); MY Solar MS730N-HJTGB tolerates heat better (temp coeff -0.240%/°C vs -0.260%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of MY Solar MS730N-HJTGB and AIKO AIKO-A805-GRH78Dw?
MY Solar MS730N-HJTGB has a module efficiency of 23.50%, while AIKO AIKO-A805-GRH78Dw is 25.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does MY Solar MS730N-HJTGB use vs AIKO AIKO-A805-GRH78Dw?
MY Solar MS730N-HJTGB uses HJT cells; AIKO AIKO-A805-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.
What is the warranty on MY Solar MS730N-HJTGB and AIKO AIKO-A805-GRH78Dw?
MY Solar MS730N-HJTGB has a 30 years power warranty; AIKO AIKO-A805-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.
Are MY Solar MS730N-HJTGB and AIKO AIKO-A805-GRH78Dw bifacial panels?
Both MY Solar MS730N-HJTGB and AIKO AIKO-A805-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.
