What it means on a roof

Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.292 %/°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: Renewsys DESERV Extreme 144X-575 or Renewsys DESERV Extreme 144X-610?
According to our database: Renewsys DESERV Extreme 144X-610 has higher module efficiency (23.64% vs 22.29%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Renewsys DESERV Extreme 144X-575 and Renewsys DESERV Extreme 144X-610?
Renewsys DESERV Extreme 144X-575 has a module efficiency of 22.29%, while Renewsys DESERV Extreme 144X-610 is 23.64%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Renewsys DESERV Extreme 144X-575 use vs Renewsys DESERV Extreme 144X-610?
Renewsys DESERV Extreme 144X-575 uses TOPCon cells; Renewsys DESERV Extreme 144X-610 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 Renewsys DESERV Extreme 144X-575 and Renewsys DESERV Extreme 144X-610?
Renewsys DESERV Extreme 144X-575 has a 30 years power warranty; Renewsys DESERV Extreme 144X-610 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 Renewsys DESERV Extreme 144X-575 and Renewsys DESERV Extreme 144X-610 bifacial panels?
Both Renewsys DESERV Extreme 144X-575 and Renewsys DESERV Extreme 144X-610 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.
