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)(BLH)/F-BH-460 or JA Solar JAM54D40-465/LR?
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 Astronergy CHSM48RN(DG)(BLH)/F-BH-460 and JA Solar JAM54D40-465/LR?
Astronergy CHSM48RN(DG)(BLH)/F-BH-460 has a module efficiency of 23.00%, while JA Solar JAM54D40-465/LR is 23.30%. 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-460 use vs JA Solar JAM54D40-465/LR?
Astronergy CHSM48RN(DG)(BLH)/F-BH-460 uses TOPCon cells; JA Solar JAM54D40-465/LR uses N-type. 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-460 and JA Solar JAM54D40-465/LR?
Astronergy CHSM48RN(DG)(BLH)/F-BH-460 has a 30 years power warranty; JA Solar JAM54D40-465/LR 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)(BLH)/F-BH-460 and JA Solar JAM54D40-465/LR 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.
