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: Astronergy CHSM54N-HC-435 or Astronergy ASTRO N5s CHSM54N-HC-430W?
According to our database: Astronergy CHSM54N-HC-435 has higher module efficiency (22.30% vs 22.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Astronergy CHSM54N-HC-435 and Astronergy ASTRO N5s CHSM54N-HC-430W?
Astronergy CHSM54N-HC-435 has a module efficiency of 22.30%, while Astronergy ASTRO N5s CHSM54N-HC-430 W is 22.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Astronergy CHSM54N-HC-435 use vs Astronergy ASTRO N5s CHSM54N-HC-430W?
Astronergy CHSM54N-HC-435 uses N-type cells; Astronergy ASTRO N5s CHSM54N-HC-430 W 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 Astronergy CHSM54N-HC-435 and Astronergy ASTRO N5s CHSM54N-HC-430W?
Astronergy CHSM54N-HC-435 has a 30 years power warranty; Astronergy ASTRO N5s CHSM54N-HC-430 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.
