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 (-0.260 %/°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: Hanersun HN18RB-54HT485W or Hanersun HN18RB-54HTB495W?
According to our database: Hanersun HN18RB-54HTB495 W has higher module efficiency (24.30% vs 23.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hanersun HN18RB-54HT485W and Hanersun HN18RB-54HTB495W?
Hanersun HN18RB-54HT485 W has a module efficiency of 23.80%, while Hanersun HN18RB-54HTB495 W is 24.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hanersun HN18RB-54HT485W use vs Hanersun HN18RB-54HTB495W?
Hanersun HN18RB-54HT485 W uses Back Contact cells; Hanersun HN18RB-54HTB495 W uses Back Contact. 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 Hanersun HN18RB-54HT485W and Hanersun HN18RB-54HTB495W?
Hanersun HN18RB-54HT485 W has a 30 years power warranty; Hanersun HN18RB-54HTB495 W 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 Hanersun HN18RB-54HT485W and Hanersun HN18RB-54HTB495W bifacial panels?
Both Hanersun HN18RB-54HT485 W and Hanersun HN18RB-54HTB495 W 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.
