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-DG-695 or Resun Solar RS9H-M-DG-720?
According to our database: Resun Solar RS9H-M-DG-720 has higher module efficiency (23.18% vs 22.37%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Resun Solar RS9H-M-DG-695 and Resun Solar RS9H-M-DG-720?
Resun Solar RS9H-M-DG-695 has a module efficiency of 22.37%, while Resun Solar RS9H-M-DG-720 is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Resun Solar RS9H-M-DG-695 use vs Resun Solar RS9H-M-DG-720?
Resun Solar RS9H-M-DG-695 uses TOPCon cells; Resun Solar RS9H-M-DG-720 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-DG-695 and Resun Solar RS9H-M-DG-720?
Resun Solar RS9H-M-DG-695 has a 30 years power warranty; Resun Solar RS9H-M-DG-720 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 Resun Solar RS9H-M-DG-695 and Resun Solar RS9H-M-DG-720 bifacial panels?
Both Resun Solar RS9H-M-DG-695 and Resun Solar RS9H-M-DG-720 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.
