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 CHSM72N(DG)/F-BH 600 or Astronergy ASTRO N5s CHSM54N-HC-435W?
According to our database: Astronergy CHSM72N(DG)/F-BH 600 has higher module efficiency (23.20% vs 22.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Astronergy CHSM72N(DG)/F-BH 600 and Astronergy ASTRO N5s CHSM54N-HC-435W?
Astronergy CHSM72N(DG)/F-BH 600 has a module efficiency of 23.20%, while Astronergy ASTRO N5s CHSM54N-HC-435 W is 22.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Astronergy CHSM72N(DG)/F-BH 600 use vs Astronergy ASTRO N5s CHSM54N-HC-435W?
Astronergy CHSM72N(DG)/F-BH 600 uses TOPCon cells; Astronergy ASTRO N5s CHSM54N-HC-435 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 CHSM72N(DG)/F-BH 600 and Astronergy ASTRO N5s CHSM54N-HC-435W?
Astronergy CHSM72N(DG)/F-BH 600 has a 30 years power warranty; Astronergy ASTRO N5s CHSM54N-HC-435 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 Astronergy CHSM72N(DG)/F-BH 600 and Astronergy ASTRO N5s CHSM54N-HC-435W bifacial panels?
Astronergy CHSM72N(DG)/F-BH 600 is bifacial (captures light from both faces); Astronergy ASTRO N5s CHSM54N-HC-435 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
