Questions about this pairing

Which panel is better: Astronergy CHSM48RN(DG)(BLH)/F-BH-450 or Jinko Solar JS182MHC120-455?
According to our database: Astronergy CHSM48RN(DG)(BLH)/F-BH-450 has higher module efficiency (22.50% vs 21.02%); Astronergy CHSM48RN(DG)(BLH)/F-BH-450 tolerates heat better (temp coeff -0.290%/°C vs -0.340%/°C). 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-450 and Jinko Solar JS182MHC120-455?
Astronergy CHSM48RN(DG)(BLH)/F-BH-450 has a module efficiency of 22.50%, while Jinko Solar JS182MHC120-455 is 21.02%. 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-450 use vs Jinko Solar JS182MHC120-455?
Astronergy CHSM48RN(DG)(BLH)/F-BH-450 uses TOPCon cells; Jinko Solar JS182MHC120-455 uses PERC. 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-450 and Jinko Solar JS182MHC120-455?
Astronergy CHSM48RN(DG)(BLH)/F-BH-450 has a 30 years power warranty; Jinko Solar JS182MHC120-455 has a 25 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-450 and Jinko Solar JS182MHC120-455 bifacial panels?
Astronergy CHSM48RN(DG)(BLH)/F-BH-450 is bifacial (captures light from both faces); Jinko Solar JS182MHC120-455 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
