Questions about this pairing

Which panel is better: Jinko Solar JS182MHC120-455 or Astronergy CHSM48RN(DG)(BLH)/F-BH-450?
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 Jinko Solar JS182MHC120-455 and Astronergy CHSM48RN(DG)(BLH)/F-BH-450?
Jinko Solar JS182MHC120-455 has a module efficiency of 21.02%, while Astronergy CHSM48RN(DG)(BLH)/F-BH-450 is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JS182MHC120-455 use vs Astronergy CHSM48RN(DG)(BLH)/F-BH-450?
Jinko Solar JS182MHC120-455 uses PERC cells; Astronergy CHSM48RN(DG)(BLH)/F-BH-450 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 Jinko Solar JS182MHC120-455 and Astronergy CHSM48RN(DG)(BLH)/F-BH-450?
Jinko Solar JS182MHC120-455 has a 25 years power warranty; Astronergy CHSM48RN(DG)(BLH)/F-BH-450 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 Jinko Solar JS182MHC120-455 and Astronergy CHSM48RN(DG)(BLH)/F-BH-450 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.
