The verdict

Identical on every published parameter

All 19 comparable parameters agree. 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
Declared annual degradation, with a 1.0% first-year loss assumed for both panels because at least one datasheet omits it, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.300 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Which panel is better: Resun Solar RS9H-M TOPCON-725 or Resun Solar RS9H-M TOPCON-730?
According to our database: Resun Solar RS9H-M TOPCON-730 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 Resun Solar RS9H-M TOPCON-725 and Resun Solar RS9H-M TOPCON-730?
Resun Solar RS9H-M TOPCON-725 has a module efficiency of 23.34%, while Resun Solar RS9H-M TOPCON-730 is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Resun Solar RS9H-M TOPCON-725 use vs Resun Solar RS9H-M TOPCON-730?
Resun Solar RS9H-M TOPCON-725 uses TOPCon cells; Resun Solar RS9H-M TOPCON-730 uses TOPCon. 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 Resun Solar RS9H-M TOPCON-725 and Resun Solar RS9H-M TOPCON-730?
Resun Solar RS9H-M TOPCON-725 has a 30 years power warranty; Resun Solar RS9H-M TOPCON-730 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.

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.
