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-48Z16/DG(BW)-430 or DAH Solar DHN-48Z16/DG(BW)-435?
According to our database: DAH Solar DHN-48Z16/DG(BW)-435 has higher module efficiency (21.77% vs 21.52%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of DAH Solar DHN-48Z16/DG(BW)-430 and DAH Solar DHN-48Z16/DG(BW)-435?
DAH Solar DHN-48Z16/DG(BW)-430 has a module efficiency of 21.52%, while DAH Solar DHN-48Z16/DG(BW)-435 is 21.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does DAH Solar DHN-48Z16/DG(BW)-430 use vs DAH Solar DHN-48Z16/DG(BW)-435?
DAH Solar DHN-48Z16/DG(BW)-430 uses TOPCon cells; DAH Solar DHN-48Z16/DG(BW)-435 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-48Z16/DG(BW)-430 and DAH Solar DHN-48Z16/DG(BW)-435?
DAH Solar DHN-48Z16/DG(BW)-430 has a 30 years power warranty; DAH Solar DHN-48Z16/DG(BW)-435 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-48Z16/DG(BW)-430 and DAH Solar DHN-48Z16/DG(BW)-435 bifacial panels?
Both DAH Solar DHN-48Z16/DG(BW)-430 and DAH Solar DHN-48Z16/DG(BW)-435 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.
