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: Runergy HY-DH108N8-450 or Runergy HY-DH108N11-505?
According to our database: Runergy HY-DH108N8-450 has higher module efficiency (23.00% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Runergy HY-DH108N8-450 and Runergy HY-DH108N11-505?
Runergy HY-DH108N8-450 has a module efficiency of 23.00%, while Runergy HY-DH108N11-505 is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Runergy HY-DH108N8-450 use vs Runergy HY-DH108N11-505?
Runergy HY-DH108N8-450 uses N-type cells; Runergy HY-DH108N11-505 uses N-type. 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 Runergy HY-DH108N8-450 and Runergy HY-DH108N11-505?
Runergy HY-DH108N8-450 has a 30 years power warranty; Runergy HY-DH108N11-505 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 Runergy HY-DH108N8-450 and Runergy HY-DH108N11-505 bifacial panels?
Both Runergy HY-DH108N8-450 and Runergy HY-DH108N11-505 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.
