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 (-0.350 %/°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: Exiom EX535MB-144BF or Exiom EX530MB-144BF?
According to our database: Exiom EX535MB-144BF has higher module efficiency (20.70% vs 20.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Exiom EX535MB-144BF and Exiom EX530MB-144BF?
Exiom EX535MB-144BF has a module efficiency of 20.70%, while Exiom EX530MB-144BF is 20.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Exiom EX535MB-144BF use vs Exiom EX530MB-144BF?
Exiom EX535MB-144BF uses PERC cells; Exiom EX530MB-144BF uses PERC. 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 Exiom EX535MB-144BF and Exiom EX530MB-144BF?
Exiom EX535MB-144BF has a 30 years power warranty; Exiom EX530MB-144BF 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 Exiom EX535MB-144BF and Exiom EX530MB-144BF bifacial panels?
Both Exiom EX535MB-144BF and Exiom EX530MB-144BF 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.
