What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°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: DAH Solar DHN-66Y18/DG-725 or DAH Solar DHN-66Y18/DG-700?
According to our database: DAH Solar DHN-66Y18/DG-725 has higher module efficiency (23.34% vs 22.53%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of DAH Solar DHN-66Y18/DG-725 and DAH Solar DHN-66Y18/DG-700?
DAH Solar DHN-66Y18/DG-725 has a module efficiency of 23.34%, while DAH Solar DHN-66Y18/DG-700 is 22.53%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DAH Solar DHN-66Y18/DG-725 use vs DAH Solar DHN-66Y18/DG-700?
DAH Solar DHN-66Y18/DG-725 uses TOPCon cells; DAH Solar DHN-66Y18/DG-700 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 DAH Solar DHN-66Y18/DG-725 and DAH Solar DHN-66Y18/DG-700?
DAH Solar DHN-66Y18/DG-725 has a 30 years power warranty; DAH Solar DHN-66Y18/DG-700 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 DAH Solar DHN-66Y18/DG-725 and DAH Solar DHN-66Y18/DG-700 bifacial panels?
Both DAH Solar DHN-66Y18/DG-725 and DAH Solar DHN-66Y18/DG-700 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.
