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 (-0.260 %/°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: Longi Solar LR7-54HVB-495M or Phono Solar PS475L7GFH-18/VBH?
According to our database: Longi Solar LR7-54HVB-495M has higher module efficiency (24.30% vs 23.27%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR7-54HVB-495M and Phono Solar PS475L7GFH-18/VBH?
Longi Solar LR7-54HVB-495M has a module efficiency of 24.30%, while Phono Solar PS475L7GFH-18/VBH is 23.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR7-54HVB-495M use vs Phono Solar PS475L7GFH-18/VBH?
Longi Solar LR7-54HVB-495M uses N-type cells; Phono Solar PS475L7GFH-18/VBH uses Back Contact. 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 Longi Solar LR7-54HVB-495M and Phono Solar PS475L7GFH-18/VBH?
Longi Solar LR7-54HVB-495M has a 30 years power warranty; Phono Solar PS475L7GFH-18/VBH 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 Longi Solar LR7-54HVB-495M and Phono Solar PS475L7GFH-18/VBH bifacial panels?
Phono Solar PS475L7GFH-18/VBH is bifacial (captures light from both faces); Longi Solar LR7-54HVB-495M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
