Questions about this pairing

Which panel is better: Astronergy CHSM66RN(DG)/F-BQ-670 or Astronergy CHSM66N(DG)/F-BH-725?
According to our database: Astronergy CHSM66RN(DG)/F-BQ-670 has higher module efficiency (24.80% vs 23.30%); Astronergy CHSM66RN(DG)/F-BQ-670 tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Astronergy CHSM66RN(DG)/F-BQ-670 and Astronergy CHSM66N(DG)/F-BH-725?
Astronergy CHSM66RN(DG)/F-BQ-670 has a module efficiency of 24.80%, while Astronergy CHSM66N(DG)/F-BH-725 is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Astronergy CHSM66RN(DG)/F-BQ-670 use vs Astronergy CHSM66N(DG)/F-BH-725?
Astronergy CHSM66RN(DG)/F-BQ-670 uses TOPCon cells; Astronergy CHSM66N(DG)/F-BH-725 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 CHSM66RN(DG)/F-BQ-670 and Astronergy CHSM66N(DG)/F-BH-725?
Astronergy CHSM66RN(DG)/F-BQ-670 has a 30 years power warranty; Astronergy CHSM66N(DG)/F-BH-725 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 CHSM66RN(DG)/F-BQ-670 and Astronergy CHSM66N(DG)/F-BH-725 bifacial panels?
Both Astronergy CHSM66RN(DG)/F-BQ-670 and Astronergy CHSM66N(DG)/F-BH-725 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.
