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.

Questions about this pairing

Which panel is better: Resun Solar RS9H-M TOPCON-725 or Resun Solar RS9H-M-715?
According to our database: Resun Solar RS9H-M TOPCON-725 has higher module efficiency (23.34% vs 23.02%). 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-715?
Resun Solar RS9H-M TOPCON-725 has a module efficiency of 23.34%, while Resun Solar RS9H-M-715 is 23.02%. 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-715?
Resun Solar RS9H-M TOPCON-725 uses TOPCon cells; Resun Solar RS9H-M-715 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-715?
Resun Solar RS9H-M TOPCON-725 has a 30 years power warranty; Resun Solar RS9H-M-715 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.
