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 (-0.300 %/°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: VSUN VSUN460N-120BMH-DG-BB or VSUN VSUN475N-120BMH-DG-BB?
According to our database: VSUN VSUN475N-120BMH-DG-BB has higher module efficiency (21.95% vs 21.26%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of VSUN VSUN460N-120BMH-DG-BB and VSUN VSUN475N-120BMH-DG-BB?
VSUN VSUN460N-120BMH-DG-BB has a module efficiency of 21.26%, while VSUN VSUN475N-120BMH-DG-BB is 21.95%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does VSUN VSUN460N-120BMH-DG-BB use vs VSUN VSUN475N-120BMH-DG-BB?
VSUN VSUN460N-120BMH-DG-BB uses TOPCon cells; VSUN VSUN475N-120BMH-DG-BB 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 VSUN VSUN460N-120BMH-DG-BB and VSUN VSUN475N-120BMH-DG-BB?
VSUN VSUN460N-120BMH-DG-BB has a 30 years power warranty; VSUN VSUN475N-120BMH-DG-BB 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 VSUN VSUN460N-120BMH-DG-BB and VSUN VSUN475N-120BMH-DG-BB bifacial panels?
Both VSUN VSUN460N-120BMH-DG-BB and VSUN VSUN475N-120BMH-DG-BB 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.
