The verdict
Identical on every published parameter
All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

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)/F-BH-470 or Astronergy CHSM48RN(DG)(BLH)/F-BH-470?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Astronergy CHSM48RN(DG)/F-BH-470 and Astronergy CHSM48RN(DG)(BLH)/F-BH-470?
Astronergy CHSM48RN(DG)/F-BH-470 has a module efficiency of 23.50%, while Astronergy CHSM48RN(DG)(BLH)/F-BH-470 is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Astronergy CHSM48RN(DG)/F-BH-470 use vs Astronergy CHSM48RN(DG)(BLH)/F-BH-470?
Astronergy CHSM48RN(DG)/F-BH-470 uses TOPCon cells; Astronergy CHSM48RN(DG)(BLH)/F-BH-470 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)/F-BH-470 and Astronergy CHSM48RN(DG)(BLH)/F-BH-470?
Astronergy CHSM48RN(DG)/F-BH-470 has a 30 years power warranty; Astronergy CHSM48RN(DG)(BLH)/F-BH-470 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)/F-BH-470 and Astronergy CHSM48RN(DG)(BLH)/F-BH-470 bifacial panels?
Both Astronergy CHSM48RN(DG)/F-BH-470 and Astronergy CHSM48RN(DG)(BLH)/F-BH-470 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.
