MY Solar MS730N-HJTGB vs MY Solar MS725N-HJTGB
VS
The verdict
Identical on every published parameter
All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

What it means on a roof
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
Same temp coeff. for both panels (-0.240 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: MY Solar MS730N-HJTGB or MY Solar MS725N-HJTGB?
According to our database: MY Solar MS730N-HJTGB has higher module efficiency (23.50% vs 23.34%). 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 MY Solar MS725N-HJTGB?
MY Solar MS730N-HJTGB has a module efficiency of 23.50%, while MY Solar MS725N-HJTGB is 23.34%. 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 MY Solar MS725N-HJTGB?
MY Solar MS730N-HJTGB uses HJT cells; MY Solar MS725N-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 MS730N-HJTGB and MY Solar MS725N-HJTGB?
MY Solar MS730N-HJTGB has a 30 years power warranty; MY Solar MS725N-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 MS730N-HJTGB and MY Solar MS725N-HJTGB bifacial panels?
Both MY Solar MS730N-HJTGB and MY Solar MS725N-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.
Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
