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 CHSM48RN(DG)(BLH)/F-BH-465 or Astronergy CHSM48RN(DG)(BLH)/F-BH-455?
According to our database: Astronergy CHSM48RN(DG)(BLH)/F-BH-465 has higher module efficiency (23.30% vs 22.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Astronergy CHSM48RN(DG)(BLH)/F-BH-465 and Astronergy CHSM48RN(DG)(BLH)/F-BH-455?
Astronergy CHSM48RN(DG)(BLH)/F-BH-465 has a module efficiency of 23.30%, while Astronergy CHSM48RN(DG)(BLH)/F-BH-455 is 22.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Astronergy CHSM48RN(DG)(BLH)/F-BH-465 use vs Astronergy CHSM48RN(DG)(BLH)/F-BH-455?
Astronergy CHSM48RN(DG)(BLH)/F-BH-465 uses TOPCon cells; Astronergy CHSM48RN(DG)(BLH)/F-BH-455 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 CHSM48RN(DG)(BLH)/F-BH-465 and Astronergy CHSM48RN(DG)(BLH)/F-BH-455?
Astronergy CHSM48RN(DG)(BLH)/F-BH-465 has a 30 years power warranty; Astronergy CHSM48RN(DG)(BLH)/F-BH-455 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 CHSM48RN(DG)(BLH)/F-BH-465 and Astronergy CHSM48RN(DG)(BLH)/F-BH-455 bifacial panels?
Both Astronergy CHSM48RN(DG)(BLH)/F-BH-465 and Astronergy CHSM48RN(DG)(BLH)/F-BH-455 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.
