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: JA Solar JAM54D40-465/LR or Astronergy CHSM48RN(DG)(BLH)/F-BH-460?
According to our database: JA Solar JAM54D40-465/LR has higher module efficiency (23.30% vs 23.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of JA Solar JAM54D40-465/LR and Astronergy CHSM48RN(DG)(BLH)/F-BH-460?
JA Solar JAM54D40-465/LR has a module efficiency of 23.30%, while Astronergy CHSM48RN(DG)(BLH)/F-BH-460 is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does JA Solar JAM54D40-465/LR use vs Astronergy CHSM48RN(DG)(BLH)/F-BH-460?
JA Solar JAM54D40-465/LR uses N-type cells; Astronergy CHSM48RN(DG)(BLH)/F-BH-460 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 JA Solar JAM54D40-465/LR and Astronergy CHSM48RN(DG)(BLH)/F-BH-460?
JA Solar JAM54D40-465/LR has a 30 years power warranty; Astronergy CHSM48RN(DG)(BLH)/F-BH-460 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 JA Solar JAM54D40-465/LR and Astronergy CHSM48RN(DG)(BLH)/F-BH-460 bifacial panels?
Astronergy CHSM48RN(DG)(BLH)/F-BH-460 is bifacial (captures light from both faces); JA Solar JAM54D40-465/LR is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
